A study of the composition and stability of complex ions of tri-
and quadri-valent plutonium in oxalate solutions. If the potassiuja.
oxalate solutions have a pH of 3.5 to 6, the complexes Pu (C2%4"
(predominant quantity) and Pu (C204)4_5 are formed. Under these con-
ditions'Pu+4 gives a clearly-pronounced reversible reaction wave,
suitable for quantitative polarogmphic determination of the plutonium.
The oxidation-reduction potential of this reaction-in one mole of po-
tassium oxalate is 0.205 v. At a pH of 6 t 8, there simultaneously
exist in the solutions two complexes of W4.

ABSTRACT: Experiments with SO 42- ions were carried out to determine the
stability constant of thorium; these experiments supplied the
distribution coefficients of thorium between the aqueous phase;
containing the ions H + and NO3 , and the solvent tributyl phos-
phate in benzene. The ionic force in the aqueous solution being
in equilibrium is kept constant in all experiments (1,7). The
experiments demonstrated that sulfuric acid is not extracted
by tributyl phosphates The experiments carried out to determine
the distribution coefficient of thorium were carried out at the

ABSTRACT: The chlorination of plutonium at increased CCl 4 pressure was
investigated. When chlorinating micro-quantities of thorium and
plutonium, it was ascertained that the sublimation of the de-
veloped plutonium chloride in a CCI 4 current at low temperature
proceeds like that of thorium. In the chlorination of UO 2 and
PuO2 by carbon-tetrachloride vapors uranium dioxide at a temper-
ature of 350-4500t is transformed into uranium tetrachloride.
At about 5000C plutonium oxide is transformed into plutonium-
III-chloride. The specific weight of FuCl 3 is 5,33 g/cm3. In

ABSTRACT: The dependence of the distribution coefficient in the extraction
of plutonium-IV compounds with tributyl phosphate was invest.4-
gated. In the calculation of the distribution coefficient the
term "true distribution coefficient" was introduced. The
distribution coefficient for n-experiments is given in the case
of subsequent extractions taking into account the apparent and
the true distribution coefficient by the equation (11):

ABSTRACT: The spectra of absorption of solid plutonium tribromide were
taken at the temperature of liquid nitrogen. A method was de-
scribed according to which plutonium tribromide can be produced
by acting HBr on plutonium (IV)-oxalate at a temperature of
50000. The specific weight of plutonium tribromide thus pro-
duced is 5,54 � 0,02. The density of plutonium 'Cribromide depends
on the composition of the compounds which are treated with HBr.
The values vary between 5,0 91CM3 and 5,8 g1cm 3. The hygroscopic
properties of plutonium tribromide were analyzed and it was
found that the bromide does not show a perceptible moisture
absorption after it has been kept over sulfuric acid for 7 hours.
The existence of two crystal hydrates of PuBr 3 was found and

TITLE: On the Ultraviolet Absorption Spectra of Plutonium Compounds
PERIODICAL: Fiz, ab. L'vovsk. un-t, 1958, Nr 4(g), PP 175 - 180
ABSTRACT: The spectrum of solutions of Pu (VI) and Pu (IV) in 2 n. perchloric and
hydrochloric acids in the 200 to 400 m 1A, region consists of one intensive
band which is apparently caused by transitions of the 5f-6d type. Its
position and absorption coefficient C (mole-1.1-cm-1) in HC10 and M
are respectively 210, 50,000,and 3,600 m ~& for Pu (VI) and 2A, 2,65o and
2,550 m w for Pu (IV) . Two bands of 236 and ^j 216 m A& are observed in
the spectrum of the hydrochloric acid solution of ni (III). When nitric
acid is added to the Pu (IV) solution, the band maximum shifts toward the
greater wavelengths (a shift of 48 m dw in 1 n. HN03), its intensity de-
creases, and a new band with a maximum of rv 320 m 4 and an C of e-1 500
emerges. In 2 n. H2SO4, on the other hand, as a result of the formation
Card 1/2 of a sulfatic complex, the 213 m ~v band shifts to 209 m and its

intensity increases. In addition, absorption appears in the 250 to 260 m It region.
When the Pu (IV)/ C204 ratio changes from 1 : 0 to 1 : 1 (the concentration of PU
remaining constan~t, C increases linearly from 2,650 to 4,500. The constant of the
Pu (IV)+HC204 - --* PuC204 2+ + reaction is equal to (3.0�1.8)- lo5. (Khim.-tekhn.

PERIODICAL: Atomnaya energiya, 1958, Vol- 5, Nr i, pp. 24-28 (USSR)
ABSTRACT: By means of a reoording pyrometer developed by Kurnakovv the
process of thermal dissociation (pyrolysis) of various types of
plutonium was investigated. The state of intermediate product'i
was determined in the Berg type gas pyrette, by potentiometrio
titration as well as by the method developed by Penfield
(Penf ill d). It was f ouna that the freshly precipitated ojaLlate
of PU (IV) loses 3 molecules of water at 1001 C. From oxalates
which had been stored for 3-4 dava 1,5 to 297% CO+CO are in
addition separated at 1000 C as a result of diBBociaiion caused
by the affect of the plutonium (k-rays. At the same time partial
reduction to trivalent plutonium takes place. Within the temper-
ature ringe of from 170-2000 0 2 molecules of water and 13%
CO+COp are, in addition,. separated. The plutonium is reduced to

At 3800 0 the oxalate is tmnsformea into plutonium dioxide. At
!400 0 the oxalate of Pu (III) is completely freed from water and
goes over into plutonium oxide at 2700 C in the air. In an inert
meaium dissociation of the oxalate takes place at 3300 C &or,-=-
panied by the formation of an oxalate carbonate. At 4600 C the
oxalate carbonate is dissooiatea and the trivalent plutonium is
oxidized to quadrivalent plutonium, while, at the same time, a di-
oxide is formed. There are 4 figures, 4 tablesq and 6 references~

It was proved that (Ref 1) the presence of ions forcing

called distribution coefficient, with the analytic.Ll concentra-
tion determined experimentally being su'hstituted for the

in dependence on the concentration of the complex forming ion
points to the existence of complex ions in the solution
(examples are given in references 2,3). It can be proved that
the change D is entirely determined by the chani~e of the
activity. The authors su~,,)-eoted a method of calculation as

TITLE: Extraction of Iron Chloride by Means of Dibutyl Ether
PERIODICAL: Zhurnal neorganicheskoy khimii, 1959, Vol 4, Nr 10,
pp 2276-2286 (USSRi'
ABSTRACT: The extraction of J?eC13 from hydrochloric acid solutions by
means of organic solvents was discussed frequently (Re-As 1-16),
but no paper gave --.he strLicture of the solvates which FeCl3
forms there in the organic phase. On passing HC1 through a
solution of FeCl 3 :.n anhydrous isopropyl ether Lorin at al
(Ref 9) obtained an insoluble precipitate of the composition
HFeCl 46 2E (E - ethiir), which dissolved on addition of water.
There are no indicutions available with respect to thet solvatim
of the compound diiisolved. In order to investigate tho com-
position of such solvatesp the dependence oftho, partition coef-
fioient, on the conoentration of the extracting agent on di-
lution with an ine:?t solvent and maintenance of all other con-
Card 1/3 ditions was invest:-gated. This method in based on the fact that

BOV/78-4-10-17/40
,Ext:raotion of Iron Chloride by Means of Dibutyl Ether
the extraction is considered a chemical reaction:
Fe3+ + H + + XE YH O.',,-HFeCl xE.yH 0 (org-organic
aqu aqu org 2 4* 2 org
phase)i If the concentration of the ions H+ and Cl- is kept
constant and no polymerization occurs the logarithm of the
partition coefficient must be a line:rl function of the equi-
librium concentration of the ether. In order to be able to
maintain the concentration of H+ and Cl-, it must be knownp how
far the acid is extracted by the ether. Therefore the first
part of this paper deals with the extraction of HU by dibutyl
ether (DBE) and ~y mixtures of DBE and CC11 and DBE and benzene
(Tables 1-3, Figs 1-3). The results indica, e that in the organic
phase the compound HC1.DBE occurs which is also confirmed by
cryoscopy. Then, t1.e extraction of FeCl3 with the same solvents
is investigated (Tibles 6-7, Fig 4)- On extraction from 10-n
HU the trisolvate FeCl 3' xHOl.3DBE.yH 20 is formed in the or-
ganic phase. If DBE is diluted with benzene, the partition coef-
ficient is directly proportional to the third power of the DBE
activity, whereas t)n dilution with CCl 4 the partition coef-

whether the resultant constants held also for the extraction

change in the composition of the solution does not affect
the values of the constants at constant ionic strength. The

TITLEs Extraction by Means of a Binary Extracting Mixture
PERIODICALs Zhurnal neorganicheskoy khimii, 1960, Vol 5v Nr 19
pp 233-234 (USSR)
ABSTRACTs In the present paper the authors investigated the extraction
of UO2 (NO 3)2 and HNO 3by means of cyclohexanone, methyl-iso-
butyl ket-,ne (hexone) and their mixture as well as the ex-
traction of FeCl by means of ethers and their mixtures.
Figure I shows 3 the dependence of the logarithm of the distri-
bution'coefficient O(on the logarithm of concentration S of
the extracting agent. The determination was carried out at
20+0.20. It was attempted to extraot PeCl 3 by means of-diiso-
propyl other (DPE) and diisoamyl other (DAE). In the extraction
of uranyl nitrate and nitric acid there is a linear dependence
of the logarithm of o~ on the logarithm of concentration of the
ketones (Kt) with a concentration of up t3 4 moles/l of the
latter. For the straight section it holds that c~= KSn

formation of the solvates HNO 3* 2Kt, U02(NO 3)2-4Kt may be seen
from the slope of the straight. The solvate HPeCl 404DPE results
in the extraotion of FeC: I whereas In the case of DAE (n.2.5)
either the formation rif t~o solvates (11FOCI 4' 2DAE and HFeCl 4*

the organic phase is assumed. Figure 2 illustrates the dependence
of the distribution coefficient upen the composition of the or-
ganic phases for the extraction with the benzene solution of
two extraoting agents. In all cases this distribution coef-
ficient was greater than the sum of distribution coefficients of
the individual components wherefrom the formation of mixed sol-
vates was concluded. There are 2 figures and 2 Soviet references.

ABSTRACT: The symposium on theory of extraction processes was
held on December 3-4, 1959, at the0stitute of
Geochemistry and Analytical Chemistry Imeni V. I.
Vernadskiy AS USSR (Institut geokhimit I analiticheskcy
khimil imeni V. I. Vernadskly AN S33R). The aim was to
evaluate the most important problems of the extraction
theory. There were five papers on questions of chemistry
and thermodynamics of extraction equilibria, on the
influence of the nature of extragents and salting-out
agents, on the composition of the extracted compounds
and their Interaction with molecules of water and the
extragent. V. I. Kuznetsov reported on "The Chemistry
of Extraction Processes," based on the theory of action

K. B. Yatsimirskiy and M. M. Senyavin were critical of
such an oversimplified approach. V. V_-Fomin presen-
ted a paper on "Extraction EquilibrTa_,T' in which the
Investigated those chemical reactions in which the
extragent participates in both phases. He notes that
an element during the extraction process need not
lose, its hydrophilic nature. A. A. Lipovskiy and
V. A. Mikhaylov together with the author discussed
the merits of the accepted view of the oxonium mecha-
nism of extraction of elements. The paper by A. V.
Nikolayev, N. M. Sinitsyn, and A. M. Shubina, "Donor-
Acceptor Properties of Extragents," dealt with the
influence of the nature of organic solvent on extrac-
tion. According to their data, an increase In dipole
moments augments the degree of element extraction.
N. N. Basargin pointed out In the discussion that-in
the case of elements having a tendency to build
covalent bonds, the result may be just the opposite.

V. G. Timoshev discussed the decisive role of donor-

The salting out in extraction processes was investigated
In the paper by 0. Ya. Samoylov and V. 1. Tikhomirov
using statistical inquiry into the thermal motion of
molecules. Basically, the explanation given took into
account the dehydrating properties of salting-out cathions.
A. A. Nemodruk pointed out during discussion that one
should take into account also the anion concentration
of the salting-out agent and other factors. A. M. Rozen
presented in his paper the use of thermodynamics In
describing the extraction equilibria. Tt was noted
dqring discussion that many thermodynamic quantities
should be measured In tests at different temperatures.
V. M. Vdovenko, A. K. Babko, D. D. Suglobqv, 1. R.
Krichevskiy, and A. A. Chaykhorskly participated also
in the general discussion. The symposium determined

recommended the establishment of a permanent seminar

The main difficulty in calculating the number of theoretical
stages lies in the reaction forming .4olvates of nitric acid and
uranyl nitrate witli TBP. Because of the large errors involved.,
the constants for the acid were assumed to remain unchanged.
Calculated values were found to be in good agreement with experi-
mental results, viz. for initial uranium and acio concentrations
of 1.26 and 2 M, respectively. An appendix is included giving
a working example for calculating a theoretical stage. There

deliend on the acidity of the aqueous solution. The number of water
molecules bound in the .4olvate (h) was determined for undiluted
ethers and for ether-benzene mixtures. The degree of hydration of
U02(NO3)2 falls with decreasing concentration of ethers in the
original benzene-ether mixture. Comparing n and h for
U02(N03)2 it was established that trisolvate8 are formed with EPE
and DPE. The value of h changes from about 3 for undiluted EPE
to 2.5 for the equimolar mixture of EPE and benzene. The values of
2 < h 4 3 are explained by the existence of di- and trihydrate* of
U02(NO3)2- In general, for the mixtures of aliphatic ethers with
benzene containing excess other, the hydratosolvates contain equal
numbers of molecules of water and ether. Dilution with benzene
gives less hydrated solvates. For undiluted MBE, n~~'4 and h S'~3-
Dilution reduces h to 2-3 and n to 3.3. The dependence of

PURPOSE AND COVERAGE: This book, which summarizes the result of studies
conducted at the Murmansk Higher Naval School, is intended for desigi
and productlon engineers, and for research workers studying the
resistance o:f metals and alloys to hydroerosion. The author dis-
cusses hydrberosion in metals and alloys and methods of increasing
the contact strength and service life of machine parts operating at
high speed in liquid media. The effect of metal and alloy structure
on their erosion resistance is shown, and the effect of a variety
of factors on the process of metal erosion are analyzed. The
mechanism and general law governing this type of deterioration in
metals, the,principles governing the proper selection of construc-
tion materials. and methods of improving the erocion resistance of
metal parts reviewed. The book contains a considerable amount of

TITLE: Energy spectra of group cignnIs In multichwinel pulse systems
PERIODICAL: Elektrosvyaz , no, 2, 1963, 3 - 10
TEXT., The theory of the energy spectra or random pulse processes with a
determined cadence -interval Is applied to sequenccu of pulsp groups. The pulses
in the group can be of dIfferent kinds. The analysis is limited to pulse group
processes where the statIstical charaoteristics of pulse groups are independent
of their number 04 In the sequence, and the utatistiloal characteristics of the
it ensemblo" of pulse groups depend only on their reciprocal position. Using the
method evolved by one of them Kevin, Teorlya sluchaynykh protsessov i yeye pri-
meneniye v radiotekhnike (Theory of randoin processes and Its application in radio
engineering), second edition, Sovetokoye Radio, 19601, the authors deduce a gen-
eval expression (consisting of a continuous and a discrete part) for the energy
spectrum F (w) of a random sequence of groups of pulses witJi a determined ca-
dence Anterval. They use thin expresslon for tho dtitermination of tha energy

of the group signal in a synchronous multiclituinel system with time-separation of
channels, under the assumption that the signal consists of m identical channel
pulses (n'1 to n*m) and one synchronizing pulse (WO), the analysis beinS limit-
ed to the case where all -the channels have Identical statistical and physioal
characteristics. The authors next deduce three separate formulae giving the
group energy spectrum in multichannel systems with pulse -amplitude, pulse-time
and pulse-duration modulation, respectively, account taken of both the useful and
parasitic modulation of pulses. There are 3 figures.

SOURCE: Radiotekhnika. v. 19, no. 1, 1964, 13-17
TOPIC TAGS: communication theory, signal plus noise envelope, normal
stationary noise, peak duration distribution
ABSTRACT: This is a continuation of a previous work (Radiotekhnika, v. 18,
no. 5. 1963) based on S. 0. Rica's findings (BSTJ, v. 37, no. 3. 1958). The
unknown probability density and integral ifunction of peak-duration distribution
are represented analytically by an approkimation method which involves these
considerations: (1) In the region of short-duration peaks, the distribution
function can be evaluated with sufficient accuracy by its first approximation;
coid"i 1/2

ACCESSION NR: AP4014671
(2) In the long-duration regiori, ihe function decreases exponentially; (3) The
area under the distribution curve is equal to 1; (4) The first moment of the
probability density is equal to a known value of the mean peak duration.
Approximation formulas are presented. A "satisfactory agreement" is claimed
between the data estimated by the above method and that experimentally obtained
by V. I. Tikhonov (UFN, v. 78, no. 3, 1962). Orig. art, has: 3 figures and
12 formulas.

ABSTRACT: S. 0. Rice (BSTJ. 1958, v. 37, no. 3) and other researchers solved

characteristics are taken as approximate probabilistic characteristics of the
Initial process. In the article, formulas are derived for independent and singly-
connected approximations to the spike-duration distribution, the between-spikes
interval distribution, and the average duration and dispersion of spikes and
intervals. The use of formulas is illustrated by an example involving a narrow-
band stationary normal process with a correlation coefficient expressed as a
Gaussian curve. Good agreement between the theoretical stepwise distribLtion
and experimental points obtained by a Soviet researcher is noted. Orig. art. has:
