TITIR: The\Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR (Vtoraya vsesoyuznaya konferentsiya MVO SSSR po radioelektronike) - News Item PERIODICAL: Radiotekhnika i Elektronika, 1958, Vol 3, Nr 3, pp 440 - 444 (USSR) ABSTRACT: The conference took place during September 23 - 29, 1957, at Saratovqkiy gosudarstvennyy universitet imeni N.G. Chernyshevskogo (Saratov State University imeni N.G. Chernyshevskiy). Apart from the universities, the conference was attended by the representatives of some scientific research institutes of the Soviet and Ukrainian Academies of Science, various industrial establishments and the interested ministries- This arrangement stimulated the discussion and evaluation of the papers presented and permitted the determinatian of plans for the future research to be carried. out by the universities in the field of radioelectronics. In view of a large number of papers and communications (over 150), the majority of these were read in various Cardl/16 sections (electrodynamics, electronics, radiowave SOV109-3-3-22~/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR t- . propagation, radio-astronomy and radiospectroscopy, semi- conductors alid their application in radio equipment). Daring the plenary session on September 23, two papers wDre read: "Development Trends of W~Y~ Electronics in the Soviet Union!' by N.D. Devyatkov and "Electromagnetic Waves in the System of Vari-directional Electron Beams" by V.M. Lopukhin. N.D. Devyatkov presented numerous- factual data illustrating the rapid development of the U.H.F. electronics in the Soviet Union and the vast contribution of tbe Soviet scientists to the theoretical foundations of this science; he also discussed the development trends of U.H.F. electronics in the immediate future. The paper described a number of original Soviet U.H.F. devices. The work of V.M. Lopukhin was concerned with the theoretical investigation of the phenomena taking place in multi-ray devices whose electron beams have different directions. The author showed that the presence of the electron beams which are perpendicular to the axis x facilitates the appearance of the solutions which are increasing functions of x for the case of n rays Card2/16 directed along the axis x ; it also leads to the SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR appearance of exponentially increasing solutions in the presence of one beam in the above direction. The Electronics Section comprised 50 papers; more than one-third of these were concerned with the theoretical and experimental investi- gation of wide-band electronic devices for U.H.F. The lecture by V.N. Shevchik, L.Ya. Mayofis and L.D.Pokrovskiy dealt with the extension of the known theories of travelling- wave tubes and backward-wave tubes to the practically import-ant cases when the delay structure necessitated the taking into account of the discrete character of the interaction of the electron beam with the high-frequency field. The lecture by V.C. Stallmakhov, V.N. Shevchik and Yu.D. Zharkov was devoted to the simplified analysis of the operation of a backward-wave tube by employing the cosinusoidal. approximation of the given field. The papers by V.B. Braginskiy, A.S. Gorshkov, A.I. Kostiyenko, G.P. Lyubimov, I.T. Trofimenko and V.V. Anisimov were concerned with the detailed experimental and theoretical investigation of the4~ossibility (first indicated by V.N. Shevchik in 195 of expanding the bandwidth of Card3/16 the electronic trimming of reflex klystrons by means of the SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR miitual synchronisation of several klystron tubes. The operation of reflex klystrons with multi-circuit resonant systems was also investigated. The results of experimental and theoretical investigation of two-ray amplifying and multiplying tubes were given in the communication by L.Z. Aitova, V.M. Lopukhin, L.A. Shkudova and in the communication of V.I. Kanavets. Some of the papers in the Electronics Section dealt with the investigations which were concerned with the development of novel U.H.F. devices, suitable for the generation and amplification of the wave- forms in the millimetre and sub-millimetre ranges. The papers of great interest were: "Experimental Investigations of the Radiation of the Electron Bunches in the Vicinity of Non-homogeneities" by V.B. Braginskiy and Ye.P. Mustell, "Comparison of the Efficiency of Certain Method:; of the Generation of Millimetre Waves" by A.S. Tager and "Applicat!.on of the Higher Spatial Harmonics of the Electro- magnetic Field in Slowing-down Systems" by A.S. Tager and V.A. Solntsev. The problems dealing with various fluctuation phenomena in electron and gas-discharge devices Ca,rd4/16and with the physics and applications of gas discharges at SOV/109-3-3-22/23 The Second All-Union Conference on RadioelectroniCB of the Ministry of Higher Education of the USSR U.H.F. were discussed in the papers by S.A.Akhmanov, I.T. Trofimenko, G.F. Antonov and N.G. Tikhomirova, who investigated the phenomena in certain oscillatory U.H.F. systems; the problem was also discussed in the papers: "The Electron Velocity Distribution in a Disintegrating Plasma" by A.M. Aleskovskiy; "Frequency and Amplitude Fluctuations of the Oscillations of a 3-cm Klystron Oscillator" by V.N. Nikonov; "De-electronisation of Gas in a 10-dm Antenna Switch" by U.V. Gorokhov and I'Detuning of Cavity Resonators by Means of Gas Discharges" by U.V. Gorokhov and I.T. B.7zova. The lecture of S.A. Kornilov entitled "Reflex Klystron as a Regenerative U.H.F. Amplifier" was of Lreat practical interest. The simplicity of the amplifier permits the application of this device in the whole range of equipment where the comparatively high level of noise is not important. The Section of Electrodynamics had six sessions, during which over 30 papers and communications were read. A considerable part of these was devoted to the theoretical and experimental investigations of the propagation of Card5/16 electromagnetic waves in various delay systems. The SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR paper by V.M. Dashenkov entitled "Scattering Properties of Certain Rod-type Delay Systems" gave the scattering equation for a structure consisting of a number of arbitrarily-loaded rods (stubs). The equation was employed to analyse single-stage stub systems and the author found that the theory was in agreement with the experimental results. The communication by V.I. Bespalov and E.Ya. Daume entitled "Propagation of Electromagnetic Waves in a Non-uniform Helix" gave the results of a perturbation-method investigation of the effect of random longitudinal and radial displacements of the helix conductor on the characteristic of the delay system. The results obtained by the authors permit the evaluation of the tolerances in the helices employed in backward-wave tubes. The paper "Generalisation of the Circuit Theory Including the Helical Delay Systems" was concerned with the possibility of the application of small perturbing objects to the measurement of the coupling impedance in a wide range of delay systems. Apart from the theoretical justification of the above method of measuring the Card6 16 coupling impedance, the paper gave some experimental results. SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR A.I. Shtyrov proposed (and proved by means of the reciprocity theorem) an interference method of the "cold" investigation of delay systemg. The method permits the measurement-of electrical non-homogeneities of delay systems, gives a high accuracy and requires comparatively little effort. The paper "Production of Periodic Structures by Mean of Ultrasonics" by Ye.M. Gershenzon was devoted to the experimental investigations of an interesting modifi- cation of a periodic structure, i.e. a regular waveguide filled with a liquid in which an ultrasonic standing wave was excited. V.P. Sazco&4v described the results of an investigation of the distribution of electric fields in a number of important delay systems (combs, stub systems, etc.) by means of two methods (probes with a high-resistance input) and small perturbing objects). The author also obtained the distributions of tangential components of the electric fields along certain boundary surfaces, which are of considerable interest. In a number of cases, the author also measured the coupling impedance. Some of the lectures were devoted to the problems of diffraction Card?/16which are important in the analysis of the directional SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the MinistrY of Higher Education of the USSR patterns of antennae. Here one should mention the papers by Ye.N. Vasil'yev and S.M. Verevkin, dealing with the excitation of the solids of revolution. The analysis of the oscillations in iT -type and tor dal volume resonators and in jr-type and cross-shaped wave~ides was given in the papers by V.L. Patrushev and V.M. Sedykh, respectively. A number of the papers in the Blectrodynamics Section dealt with the complex phenomena appearing at the junctions of waveguides. Here, it is necessary to mention the papers: "The Calculation of Junctions" by Ya.M. Turover; "The Problem of Construction of Certain Wideband Matching Device8n by Ye.V. Anisimov and V.D. Luchinin and "Measurement of the Parameters of the Energy Outputs in U.H.F. Devices by Means of a Symmetrical Transformer" by I.A. Dukhovnikova and M.M. Rayner. The behavioiir of various substances in electromagnetic fields at U.H.F. was discussed in the papers of O.V. Karpova, U.P. Radin, I.A. Shekhtman, A.I. Pilshchikov, A.L. Levinson, N.S. Sedletskaya and A.A. Kuznetsov. In the Radio- Card8/lEspectroseopy and Radio-astronomy Section, the most important papers were delivered by N.G. Basov, I.D. Murin, A.P.Petrov, SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR A.M. Prokhorov, I.V. Shta~anikh, K.K.Svidzinskiy, A.N. Orayevskiy, U.L.Klimontovich, R.V. Khokhlov, G.H. Vasneva, V.V. Grigorlyants, M.Ye. Zhabotinskiy, D.N. Klyshko, V.L. Sverdlov, Ye.I. Sverchlov, and V.V. Nikitin which dealt with the results of the theoretical and experimental investigations of various types of molecular oscillators (masers). 'The paper of N.G. Basov and his collaborators described the principle of operation of a molecular 'ilock having an accuracy of 10-9. The results of a theoretical investigation of the molecular radiation in high-frequency fields were given in the papers of V.M. Fayn, entitled "Radiation of the Molecules in Strong High-frequency Fields" and "The Spontaneous Radiation of Molecules at Ultra-high Frequencies". In the second of the above papers, the author came to the con- clusion that the width of the spectral line of the spon- taneous radiation at U.H.F. is finite. The author also proposed a classical analogy for the phenomenon of coherence in the spontaneous radiation. I.A. Deryugin Card9/16 investigated in his paper the revolution of the plane of SOV/109-3-3 T2?Z;~ 3 The Second All-Union Conference on Radioelectron-ics o e Jnstry of Higher Education of the USSR polarisation and the ferromagnetic resonance in colloidal iron nickel, cobalt and permallol. The experiments were carried out over a wide band of frequencies and showed a strong dependence of the above effects on the losses in the samples. The works of A. M. Prokhorov, V.N. Zverev and 'U.S. Korniyenko were devoted to the investigation of the fine and ultra-fine structure of the spectrum of the electron par&magnetic resonance of the ions of chromium and iron in the lattice of aluminium. oxide. The radio- spectroscope, constructed by the first two authors, made it possible to reveal the signal from a sample containing 3 X 10-11 mol of the paramagnetic ions of Cr3+ . The paper by V.V. Zheleznyakov, in which the author suggested a hypothesis concerning the origin of the sporadic radiation of Jupiter, aroused a considerable interest and lively discussion. According to the hypothesis, the bursts of the radiation from Jupiter are due to the plasma oscillations in its ionosphere. The author found a close correspondence between the parameters of the ionosphere of CardlO/16ftiter and those of the layer F2 of the Earth ionosphere. SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR The paper contained also a hypothesis dealing with the analogous mechanism of the recently discovered sporadic radiation of Venus. The work of G.G. Getmantsev entitled: "The Theory of Magnetic Braking Mechanism of the Non- thermal Cosmic radiowave Radiation" eliminates the theoretical difficulties which are encountered when an attempt is made to consider the galactic plane as being the source of cosmic electrons. The author considered that the electrons are formed as a result of uon-el .c collisions between the relativistic protons 81; ONI6 stellar medium. I.G. Moiseyev described a 10-cm radio telescope, having a mobile (vibrating) directional pattern. The movement of the pattern is secured by periodically switching the input of the receiver from one antenna radiator to another, the radiators being situated in the vicinity of the focus of a parabolic reflector. G.G. Getmantsev described a simple modulator (switch) which was constructed for the above equipment at the Gorlkiy University by N.N. Kholodilov and A.V. Zakharov. The Radiowave Propagation Section had Cardll/16nine papers and communications. The paper by B.N.Gersham SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR entitled "The Theory of Large-scale Non-uniformities" proposed a theory analogous to that of the cellular Martin waves, which also took into account the effect -of the magnetic field of the Earth. N.G. DeALsov gave a theoretical analysis of the propagation of radiowaves through that region of the non-uniform magnetically- active plasma in which a partial absorption -of the electro- magnetic waves takes place due to the vicinity of the frequency of the external field and the natural frequency of the plasma. The author calculated the reflection coefficients and the propagation and absorption coefficients of the extraordinary wave for the transverse propagation and investigated the absorption of the ordinary and the extraordina~ry waves for the quasi- longitudinal propagation. The influence of the solar activity on the ionosphere was investigated in the papers by N.N.Yeryushev and N.A. Savich. As a result of the systematic measurement of the overall intensity of atmospherics at frequencies tW 13-42 kc/s the various properties of the radiowaves were studied. Some con- Cardl2/lEclusions relating to the influence of the chromospheric SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR explosions on the sun on the ionosphere were also arrived at. The paper by A.A. Semenov and G.A. Karneyev entitled: "The Problems of the Statistical Evaluation of the Results of Measurements in the Investigation of the Rapid Fluctua- tions of Ultra-shortwave Radio Signals" aroused considerable interesti similarly, the paper by A.A. Semenov and Ch.Ts. Tsydypov under the title "Investigation of the Variations of the Dir-ect Radio Signal Propagation in the Non-uniform Troposphere over a Ground Path" was of con- siderable interest. The latter paper gave some results of an experimental investigation of the fading of the direct ray over a medium-distance ground path. The statistical characteristics of the amplitude fluctuation of the signal were investigated and an attempt was made to clarify the mechanism of the signal variations. During the ensuring discussion, the great practical value of the above works was emphasised and it was suggested that the work should be extended -in order to attain a greater accuracy. Twelve papers and cominuidcations were read at the Semi-conductor Section. L.C. Berman gave an approximate method of Cardl3/16'ealculating the transients in a transistor operating with SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR large signals. The method was based on a quasi-linear approximation and the transientwas regarded as a switch- over from a conducting state (with constant equivalent parameters of the circuit) to a nonQbnducting state with zero-value parameters. The switch-over point was taken as the instant when the charge and the voltage on the base- emitter capacitance is zero. The author showed that the method is in good agreement with the experiment. "The Detector Crystals of Pressed Germanium" by Z.I. Kirlyashkina, described the technology of the prep- aration of germanium wafers for press-method diodes, whose main advantage is an almost complete absence of the loss of germanium. The results of an investigation of samples of p-n junction diodes showed that the method was promising for industrial applications. The influence of adsorption and illumination on the change of the contact potentials in.the films of selenium and tellurium was investigated in the work of V.F. Bogolyubov, U.F. Lushkin and I.A. Nakrap. A paper of V.V.Pasynkov and Ya.I.Panova described the experiments on the development of semi- Cardl4/lEconductor loads for waveguides. The basic material was SOV/109-3-3-22/23 The Second All-Union Conference on Radioelectronics of the Ministry of Higher Education of the USSR made of ultra-china clay (binder) and of of nt5rains silicone carbide (the absorbing compone . The investi- gation showed that the samples produced had satisfactory characteristics. The development or non-linear semi- conductor resistances was described in a paper of V.V. Pasynkov and L.K. Chirkin; resistance elements for powers of 10-15W were produced and their applications were studied. A method of calculating an inverse peak current in p-n diodes was given in the paper of' L.I. Baranov and M.C. Bekbulatov. The formulae obtained made it possible to explain various forms of the peaks observed in the experiments. The paper by Yu.N. Azlyan, G.N. Berestovskiy, L.N. Kaptsov, V.V. Migulin, K.S. Rzhevkin, K.Ya. Senatorov and T.N. Yastrebtseva contained a survey of the works dealing with the appli- cations of transistors in various radio circuits. The transient processes in the base of the transistors were thoroughly investigated. The delay between the input and the output signals in a transistor was thought to Cardl5/16 provide the possibility of designing an oscillator without V.OV~10 -gf '~ff/JLstry Lr '2 The Second All-Union Conference on Radioelec r0 c e of Higher Education of the USSR reactive elements and such oscillators were actually constructed. Some important engineering methods of designing various transistor circuits were developed. G.N. Berestovskiy read a paper in which he gave the analysis of the operation of a transistor AC-DC converter. The experimental data corroborated the accuracy of the foxmulae proposed by the author and showed that a high conversion efficiency could be obtained with a number of Soviet trarasistors. During the conf erence, a number of trips were arranged to various industrial establishments of the town of Saratov. During the closing plenary session of the conference, on September 28, a unanimous resolution summarising the work of the conference and containing recommendations with regard to the subject matter and,the plans for the future work was adopted. It was also decided that the third All-Union conference of the Ministry of Higher Education of the USSR on radioelectrons would be held in Khar1kov in September, 1959.

Sh__Ye u" TITLE: A Variational Method for Designing the Waveguides Having Periodic Inhomo- geneities - Part I (Variatsionnyy metod rasoheta volnz)vcdov a periodiche- skimi noodnorodnostyami - Chast' I ) PERIODIOAL: Radlotekhnikit I Elektronika, 1-357, '"Vol 2, Nr 1, pp 3-14 (UWR) ABSTRAUT: Pri3pagation. of electromagnetic wwres in a periodically corrugated waveguide with ideal-conductor walls and with less-free inside medium is examined. It is pointed out that the square of the wave number of propagating wave can be determined as a stationary value of the functional (12). It is found that, for the variational problem Involved, bakndary conditions are natural. In other wo::ds, permissible funotions that minimize the functional (12) should not necessarily satisfy the boundary conditions. Theoretical investigations of propagation in periodic wavegaides use three fundamental methods: the perturbance method, the jolaing method, and the varia- tional method. The first method Is rarely used in praotioe. The joining method JLB Ofter, succe3sfully u3ad when the =mbsr of inhomogeneitles per one wavelength Is great. In the case of spatial-harmon-io TW tubea, however, the inhomogeneity length is comparable to the waveleneh. It is vary difficult to apply the joining method in such cases. The variational m6thod is applicable to delay systems. It permits evaluating the absolute -7alue of ex-.-)r in determination of fields and phase velocity. The last two methrds are appli,,~able only in those cases Card 1/3 109-2-1-1/17 A Variational Method for Designing the WaveguideE.(,Cont.) when a waveguide call can be subdivided into a number of ranges for which Maxwell's equations, Sat4efying the boundary conditions at the waveguide walls, are known. If the corrugation shape does not satisfy the above condition, both methods become Inapplicable. Yet, such waveguides may conceivably be used for correction of dispersion characteristics or for optimum field distribution in an interaction space. An attempt is made in the artiale to apply the well- known Ritz variational method to the calculation of fields In and dispersioa chara,,ateristics of a corrugated waveguids. The vector equatia.; for a field rot rot H = k2l~'(wh6re I is field vector, k is wave r~umber) is based on the classic Maxwel.19s equattions. Starting from it and using a number of integral transformations. and also the Ostrogradsk-j--Gena6 -theorem, the author proves that the rot rot operator is self-adjo In', and t1hat the bcandary conditions are natuial. In principle, the variational method permits determining the disper- sion characteristics and field pattern of a periodical],7 corrugated vaveguide of any shape, and als6 determining of natural frequencies of cavities and criticol wavelengths of regular waveguides. On the other hand, the method is Inapplicable for description of the field pattern in rejection band when the walls and the interral medium of the gaide are not ideal or when a periodic guide contains an electron beam. The variational method is illustrated by an example: an approximate calculation of a dispersion equation for two parallel planes, one of which has rectangalar goffers of arbitrary size. Card 2/3 A Variational Method for Designing the Wavegaides . (Cont.) 109-2-1-1/117 The following conclusions are offered: The dispersion relation - propagating-wave phase-velocity / frequency can be determined by means of Ritz' variational method. The square of the wave number of a wave propagating in a corrugated waveguide having calls of any shape can be determined as a mininum of the definite functional (12) spread over the range of one cell and having natural boundary conditions. A similar variational method can be used for determination of fields and natural frequencies of any resonatora because the boundary conditions are natural also in cases of variation of mag- netic field intensity. The same method can be used for determination of field patterns and critical W~avelengths of a regular waveguide of any cross-section (this Is a particular case of the corrugated -waveguide). The basic disadvantage of the method lies in the tundamental difficulty of allowing for an electron beam or for finite conductance of the guide walls and internal medium. A dispersion equation for a delay system comprising two parallel sheets with rectangular goffers is a higher-order approximation as compared to Kleen's and Ruppel's Ref 7 dispersion equations, Acknowledgomentri go to ProfesnoT P.V.

The variational method, developed in the first part of this article (RadJ.otekhnika i Elektronika, January 1957, Page 3) is extended to in- clude the case when the geometry of the periodic waveguide (resonant cavity) admits~of the use of the partial-region method. A theory is derived for the determination of a pair of dispersion curves (and of natural frequencies respectively), located on both sides of the true dispersion curve, a fact of great importance in the estimate of the accuracy of the results. As an example., the procedure developed was used to obtain the disper- sion equation for a decelerating rectangular corrugations of finite thickness, and various dispersion curves are calculated for several va- lues of dimensions of this system.

This was expressed by equations (1) and (2), where 0 is the volume of I cell of a periodic wave-guide and vectors 12 and # should satisfy a relationship of the Floquet type following from the periodicity of the wave-guide, as given by equation (3). It is also shown (the derivation is given in the appendix, p. 985) that the variational method can be given in terms of an alternative rule, from which it followo that,ifft agiven tangential component of the magnetic field H t over a surface 8 (where the meaning of S and other symbols referred to later can be seen from Fig.1): k2 . min J1 (10) Cardl/4 then for a given tangential electric field: 109-8-4/i/ Vuriational Method of CalculatinG the Wave-guides with Periodic DI sccj.,AU i nul t i. e 2.

Turbulent mixing is achieved by use of E- and O-type electromagnets. The electromagnetic forces lead to very strong mixing especially when the metal trough is not completely fil- led.,- metal C .-Yransparent channels were used to observe the behavior of a test - MOL-- cury)r~n the mixing chamber. The efficiency of energy,transfer reaches about 90% and does not'depend strongly on the wall thickness, thus making this method suit- able for high temperature operation. Experiments with single phase mixers did not,--- Card, 1/2 L 1391-66 I-ACCESSION NR: AP5016662 0 permit any wide variation of parameters. A new magnetodynamic device has been constructed and studied to mix mercury and water or powder-like substances. Var- ious mixing regimes were observed by changing relative phases between the mixer magnets. The main advantages of the new system, which is suitable for admixing any material, Are the small electric losses. Heat losses during the flow through the mixer are compensated and some additional heating may occur due to currents flowing in the mixed metals. Orig. art. has: 4 figures.

TITLE: Use of single-phase electromagnetic pumps in foundry practice PERIODICAL: Liteynoye proizvodstvo, no. 8, 1962, 9 TEXT: In foundry practice, two types of induction pumps show the greatest prospects -~ three-phase and single-phase pumps. Three-phase pumps are more ex- pediently employed in the continuous pumping of considerable meta '1 quantities over a long distance, while single-phase pumps are more suitable for the intermittent pumping of smaller amounts of metal at low pressure. The mqtal filling a ring- -shaped crucible constitutes the second winding of a single-phase transformer with the primary winding under the crucible. When the primary winding isalitched on, currents are induced in the liquid metal that are interacting with-the magnetic field of the transformer, while forces are originating in the metal striving for moving it upwards relative to the coil. During long-time standstills the pump can operate op a reduced voltage which keeps the metal in a liquid state. Single-phase pumps are applicable-for proportioning and feeding the metal into pressure casting, Card 1/2 S112C~,1621GG01908100 1"-,3 Use of single-phase .....

TITLE: Production of Technical Py'rene PERIODICAL: Koks i khimiya, 1961, No. 1, PP. 52-55 TEXT: Pyrene is one of the important raw materials for the production of dyes and for this reason, the authors carried out an investigation of the potential resources, methods of separation and treatment of narrow pyrene fraction suitable for the prepar- ation of products of various qualities from coal tar. In the USSR the coal tar is treated mainly on continuous plants for the production of a standard medium temperature pitch. The production of a high temperature pitch is done not by steam distillation, but by oxidation with air. Therefore, the raw materials for the production of pyrene are not "steam" but "air" pitch distillates. The pitch distillates (from the Zaporozhlye Coking Works) taken for the investigation had the following properties: s.g 1.120 at - 200C, pyrene content 4.856%; begimaing of boiling 140*, iVlo at 280*, 19% at 3000, 300% at 3360; 400%, a+- 3550, 52% at 3820, 660% at 3930, 72% at 410*, 8011o at 421*C. Th( istillates were fractionated on a Card 1/4 3/068/61/000/001/001/001 E071/E235 Production of Technical Pyrene laboratory colilmn equivalent to 13-15 theoretical plates. On distillation, two narrow g,,_ rene fractions were collected: 1) 384-388*C amounting to 6-5% of the initial pitch distillate containing 33.0% of pyrene and 2) 388-395'C amounting to R., and containing 48.2% of pyrene. The raw pyrene fractions were sub- mitted to recrystallisation from various solvents. Optimim resultc were obtained from 3001o aqueous pyridine and 3051b alcoholic solution of solvent naphtha. The crystallisation conditions and results obtained are tabulated. It was found that recrystallisation of raw pyrene fractions containing less than 4051c of pyrene give a mixture of pyrene with fluoranthen, which cannot be further enriched by this method and repeated recrystallisations lead only to losses of pure products, e.g., after four recrystallisations of fraction containing 2?% of pyrene a product containing about 450% of pyrene was obtained with pyrene recovery of 58.4%. Subsequent recrystallisations were ineffective. Fractions containing 407a and more of pyrene can be easily enriched to ?5-80%. The more concentrated is the initial pyrene fraction, the more concentrated Card 2/ 4 S/068/61/000/001/001/001 E071/E235 Production of Technical Pyrene a recrystallisation product can be obtained, e.g., a fraction containing 52.6% of pyrene after double recrystallisation yielded 96-97% technical pyrene (from a mixture of petrol and solvent naphtha in a ratio of 1:1). In addition to pitch distillates, anthracene oil II was tested as a possible source of pyrene. Properties of the oil: beginning of boiling 251*C, at 308'C - 1CO/c, at 3180C - 20%, at 327*0 - 307p, at 3340G - 407p, at 3420C - 50%, at 349*C - 601c, at 365*C - 75%; pyrene content 1.32%. A narrow pyrene fraction obtained from this oil contained 29% of pyrene and about 701% of fluoranthen. This fraction could not be suff- iciently enriched by recrystallisation they-efore, anthracene oil II can be used for the production of fluoranthene and not of pyrene. It is concluded that technical pyrene of 96-97% purity can be obtained from pitch distillates with a recovery of pyrene of about 70% and of 70-807t, purity with a recovery of pyrene about W15. The head fraction obtained on rectification of pitch distillates after the removal of crystals can bb-used as an impregnation oil for sleepers and in the raw state as a material Card 3/4
