TITLE: The Investigation of the Exchange of Tungsten Isotopes in Some
Isopolywolframates (Izueheniye izotopnogo obmena vollframa v

ABSTRACT: Previous papersby the authors (Refs 1,2) point to the different
2-
linkage of the second sulphur atom in 3 0 . The mobility of
2 7
the S-atoms decreases with increasing diameter of the cation.
In this paper a parallel investigation of isopolywolframates
is carried out. In this connection it is assumed that due to
the longer diameter of the tungsten atom the linkage in the
anion is less covalent and more ion-like. Mercury salt was sep-
arated from Na 2W04 with W185(Tj - 73.2dd4s).,by annealing it was

transformed into marked anhydride of tungstic acid and the
distribution of radioactive tungsten was investigated after

(Radiatsionnyy metod polucheniya platinovogo katalizatora)
PERIODICAL: Zhurnal fizicheskoy khimii, 1959, Vol 33, Nr 39 PP 736-737
(USSR)
ABSTRACT: Though various papers have already been published on the
effect exercised by ionizing radiations on catalytic re-
actions (Refs 1,2)9 the action of radiations has not yet been
employed in the production of the catalyst . In this case the
authors investigated the separation of metallic platinum
from some of its complex compounds by the action of-a flux
of fast electrons; further, they studied the structure and
catalytic properties of the precipitates obtained. A radiation
source was applied as a linear electron accelerator with
1'-5 mev (Ref 3). The capacity of each dose-was determined by

H~ A. Shishakov made X-ray analyses which indicated that
crystalline platinum and the partially unreduced compounds
of Pt 4+ are presen t in the precipitate. The most interesting
results were offered by saturated solutions of Na 21Pt(OH).Cl6-x"
in 2 a NaOH at doses of 2.10 21 eV/cm3, In this case a black
platinum precipitate was obtained; the particle size of which
depended on the concentration of the solution and the time
of irradiation. The reduction to the metal is perfect in this
case. The platinum precipitates obtained were checked-with
respect to their catalytic activity in the reduction of the
low-temperature hydrogenation of cyclohexane and were com-
pared with platinum catalysts produced by Loev's (Levis)
method. During the first days after radiolysis the afore-
said catalysts were more active by fifteen to twenty times3
later this activity decreased, yet remained above that of
the catalysts according to Loev. The experiments will be

TITLE. An Investigation of the Composition of the Uranates of Alkali
Elements Produced by a Dry Procedure (Issledovaniye sostava
uranatov shchelochnykh elementov, poluchayemykh sukhim putem)
PERIODICAL: Doklady Akademii nauk SSSRp 1959~ Vol 124, Nr 59 PP 1057-1060
(USSR)
ABSTRACT: The interaction of uranium oxides or uranium salts with oxides
and salts of alkali metals at high temperatures results in the
formation of monouranates of alkali metals, moreover, of di-
uranates of Li., Na~ and K; finally, Na U 0 and
2 3 10
VOW 6H,.O can be produced from uranyl sulphate with NaCl
and KC1 (Refs 1-3)., There are no exhaustive statements in
literature as to what uranates of each alkali metal are
formed in this case. The statements made by W. & Zachariasen
(Zakhariasen~, Ref 5) on hexagonal and pseudohexagonal layers
in the Li-, Ila-, and X-monouranates are inconsistent with
statements made by other research workers (Ref 7). This di-
Card 1/3 vergence may be due to polymorphous modifications. The authors

An Investigatton of the Composition of the Uranates SOV/20-124-5-20'/62
of Alkali Elements Produced by a Dry Procedure
investigated the conditions for the recovery of said uranates,
which are formed when UO 3 and U308 are heated in air with the
carbonates of corresponding elementsv and the composition of
said uranates (by thermal aud X-ray phase analysis). The
components were used in amounts corresponding to the formation
of uranates with various MeIO- and UO ratios~ After discus-
2 3
sing the resulting uranates of several alkali metalsy the
authors state that the indications given in the literature
(Ref 1) on the behavior of the uranates at high temperature
do not convey a proper impression of their thermal stability.
Table 1 shows the results obtained by heating monouranates
between 700 ana 1,1000 in intervals of 1000. It was found that
lithium monouranate is thermally stable and does not decompose
within 60 hours at 10000. On the other hand, Na-9 K-, and Rb-
uranates decompose at 1,200-1,3000, forming diuranates;
CS2U0 4 decomposes at 192000 within 6 hours. Thus, the
stability of the monouranates decreases from Li 2UO4 to CS 2U0 4'

TITLE: Tungstates of Zirconium and Hafnium (Vollframaty ts-4rkoniya i

ABSTRACT: The data given in publications on the substances mentioned in
the title is very rare and contradicting (Refs 1-4). The pres-
ent paper deals with the synthesis of hydrated and anhydrous
tungstates and with the investigation of some of their proper-
ties4 The first were obtained by the interaction between zir-
conyl- or hafnyl nitrate solutions and ammonium tungstate. Their
molecular ratio was 1:1. Zr- or Hf hydroxide was precipitated
when the pH of the solution amounted to more than 3.2. Colloidal
precipitation was produced between pR 1.8 and 3.2 which coaga-
lated in the case of heating in a NE

initial substances reacted fully according to the analysis. An-
hydrous tungstates were obtained by sintering (6 hours) oxides
Card 1/3 or hydroxides of the afore-mentioned elements with equimolar

Tungstates of Zirconium and Hafnium SOV/20-127--l-32/65
quantities of tungstic acid. The formation of the new phase was
controlled by radiographic analysis. White fine-crystalline
substances with radiobrraphs which are very similar to one an-
other are produced when the sintering products are chilled. The
above tungstates are not produced if the chilling is carried
out slowly. 1:1-compounds containing an excess of the component
concerned were produced by sintering mixtures of ZrO 2 and Hf62
with WO3 in other ratios than 1:1, e.g. 1:2P 1:3. and 2:1. The
radiographs did not show new lines indicating only 1:1 oxide#.
The compounds produced were analyzed by alkaline and pyrosul-
fate exposure. Table I shows the results. Accordinglyq the.sub-
stances synthesized are to be ascribed to the following formu-
las: ZrOWO 4'1.5H2 09 ZrOWO49 HfOWO4_2H2O and HfOWO,. Hydrated
zirconyl- and hafnyl tungstates are white radioamorphous sub-,
stances which absorb humidity in air. Either the symmetry of
the crystal lattices of anhydrous Zr- and Hf tungstates is low
(their radiographs show more than 70 lines), or at least one of
the axial parameters has high values. The high values of the
Card 213 angle of glide agree with the low density values: 5.27 for

TEXT! The authors determined the optimum conditions for producing Iammoni=/
scandium carbonates, and described the properties of these compounds.
The compound NH 4Sc(co 3)2.1.5H,,O was produced by dissolving freshly pro-
duced scandium hydroxide in a concentrated solution of ammonium carbonated
and subsequent crystallization at room temperature. This compound is stable
at room temperature, and decomposes only at 950C under formation of dif-
ficultly soluble basic scandium. carbonate whose composition is not con-
stant. The thermal decomposition of ammonium scandium carbonate was thermo-
graphically studied by means of a Kurnakov pyrometer. It was observed that
the ammonium scandium. carbonate decomposes gradually. At 140-1900C,

temperature range of 280-3050C, crystalline ScO(OH) is formed which
passes into Sc 203 at 4800C. At 4000C, NH 3 and CO2 are completely liberated.
The solubility of scandlum hydroxide at 0. 25, and 500C in solutions of
(NH 4)2CO3 of different concentrations was studied. It was observed that
the solubility of scandium hydroxide at higher ammonium carbonate con-
centrations and lower temperatures is higher. In a '17.B% solution of
(NH4)2 CO3-H20, scandium hydroxide is soluble at OOC up to a concentration
of 1.24% by weight of Sc 2030 Amorphous ammonium scandium. carbonate
NH 4Sc(CO3)2' 2H20 is formed by dissolution of scandium hydroxide in ammonium

temperature range of 0-250C. The amorphous ammonium scandium carbonate
passes into the crystalline state above 500C. The thermogram of amorphous
ammonium scandium carbonate shows an endothermic effect at 65-1100C
caused by the cleavage of water, which is characteristic only of the

TEXT: This is a reproduction of a speech held by the author on the occasion
of the 550th anniversary of Leipzig University. To begin with, the author
gives a survey of the development of the Soviet chemical industry in the
perLod from 1918 to 1957. The Seven-year Plan (1959 - 1965) provides for an
about trebled annual production of the chemical industry. This will be 300
to 350 times the Russian chemical production in 1913- Investments will
amount to 100 - 105 billion rubles. A total of over 140 large chemical
plants will be built or completed; over 130 establishments will be recon.-
structed. Special care is devoted to the production of synthetic substances.
The production of synt6etic fibers will be increased by four times, and
that of tne more valuable among them by 12 to 13 times. The production of
Card 1/6

plastics and synthetic fibers will be increased by more than seven times.
The production of mineral fertilizers is to be trebled. To make all this
increase possible, all branches of the chemical -industry are required to
mechanize and automatize their operational processes to the utmost. More-
overs it will be necessary to work out new anticorrosive substances for use
in apparatus constructions The most important task confronting SoTiet
scientists, however, will be the widest possible extension of theoretical
research to prepare the ground for the development of new te4hniques and the
production of syntnetic materials with properties meeting the demands of
modern technology. The principal part of the author's speech was a report
on Soviet researchers' most important contributions to the present level of
Soviet chemistry~ Thefollowing Soviet scientists are mentioned in this

(USSR)
ABIMACT; The present report deals with the stereochemistry of uranyl
compounds with Schiff's bases. The compounds mentioned in this
paper may be divided into three groups according to the type of
the ligand. The authors used three types of Schiff's bases
which had been obtained from ethylene diamine (A), aromatic
amine (B) as well as from 2-amino-pyridine (V) (see scheme).
The analysis reveale4 that the uranyls of type I never contain
more than 1 molecule of the solvent (Table 1). The molecule
can be removed only by prolon-3ed heating at 160-180 0. The na-
ture of the complex and the difficult elimination of the sol-
vent molecule suggeut that a donor-acceptor-bond may be formed.

is 7 and will be 6 after elimination of the solvent-molecule.
In the second type of the uranyl complexes7the case is quite a
different one: they contain 2 pyridine molecules which cannot
0 . 0
be removed even by prolonged heating at 160-180 .At 200-220
the complexes are destroyed. Also in this case a donor-accep-
tor-bond is probably formed. The coordination number of the
hexavalent uranium in such complexes apparently equals 8.
2-Salicylal-aminopyridine (contrary to salicylal-aniline) readily
forms a complex with uranyl even in a neutral medium. As the
former differs from the latter only by the occurrence of
heterocyclic nitrogen, such a considerable increase in the
capability of complex formation may be attributed to hetero-
cyclic nitrogen. It was, however, not possible to produce a
complex of uranium with 3-salicylal-aminopyridine. Accordingly,
the stability of the complex depends mainly on the position of
the heterocyclic nitrogen with respect to the azomethine-group.
It was confirmed by analysis that complexes of this type contain
no molecules of the solvent. Herefrom the authorsconclude that
in the complex compounds of uranyl with azomethinel-derivatives

hexavalent uranium takes place. This is possible only if the
heterocyclic nitrogen is coordinated with the central atom.
The coordination number of uranium in these compounds is, most
likely, equal to 8. Thus, uranium, according to the properties
of the Schiff's base, shows a variable coordination number.
Taking into account that the uranyl ion has a linear structure,
it follows that, from among all possible structural models of
the hexavalent uranium complexes with the coordination numbers
6, 7 and 8, such would have to be given preference, in which
the ligand atoms combined with uranium are placed in a plane
vertical to the direction 0 - U - 0. Since the high stability
.Of UO 2+ is due to the participation of the 5 f-orbits of
2
uranium in the bindings with oxygen (Ref 8), the structure of
the complexes for the.coordination numbers 5. 7 and 8 will cor-
respond to a tetragonal bi-pyramid Of 36d27s) I, a pentagonal
bi-pyramid (506d378) II and a hexagonal bi-pyramid

two reaction mechanisms alternate each other, In the range of
activities from hundredths of millicurie/g to 3 millicuries/gg
the isotopic exchan6e is increased by the appearance of posi-

of continuous irradiation of/j-particles. The drop of exchange

calculated according to Arrhenius, the reaction rate constant
by the equation 1n 100/(100-IV) - kt, where W denotes the yield

by figure 3, the left side of the equation is linearly dependent
on t. The exchange rate in the system Na. 60 - SO showed the

ABSTRACT: It was the aim of this paper to investigate the action of the
radiation of a betatron upon the isotopic exchange of a weakly
traced K 2io 4-preparation with SO 3-vapors.IFigure I shows the
scheme of the remote-controlled experimental apparatus, which is
described. Temperature was kept at 8400 with an accuracy of e0.
The electron beam had an energy of 5 Nev. The course taken by the
experiment was followed by means of television. The K �0 -prepara-
2 2 4
tion had a specific activity of 4.6.1o- millicurie/q. The radia-
tion dose was determined by means of Fe(II) sulfate (spectrophoto-

ated by means of a betatron. In the determination of the total
doseq the specific weight, volume, and ratio between the elec-
tron density of the substance concerned and the electron density
of water were considered (Table 1). No radiochemical decomposi-
tion of K2SO4 was observed in any of the experiments. Table 2
gives examples for the change in the activity of K2 so4 resulting Lo~
from irradiation. In table 3, the mean values of all experiments
are given. The authors obtained the following results: The ex-
ternal irradiation of the solid phase of the K 2304 - so 3-system
by means of electrons exerts no influence upon the rate of iso-
topic exchange in the case of a dose of the order of 1015 ev/102in.
With an increase of the dose to 10 16 _ 1017 ev/10 min, an in-
crease in the exchange yield occurs, which is directly propor-
tional to the logarithm of the dose (Fig 7). The P-radiation of

TEXT: The authors describe the conditions of formation of zirconium tantalate

are highly resistant to HC1 (36%), H2F2 (25%), H2SO4 (90), and NaOH (40%)-
They were beat dissolved in H 2F2 where tantalate is more resistant. It is prac-
tically insoluble in hot-concentrated HCl- and H 2 so4solutions, in H2so4 and
ammonium sulfate mixtures. Also together with sodium pyrosulfate, K2 CO 39 and
sodium peroxide it cannot be melted. The undissolved portion of the two zitoonyl
salts remains unchanged which indicates a high chemical resistance of these
compounds. There are 2 figures, 2 tables, and 5 references.

TITLE: Radiation Method of Synthesis for Some Derivatives of Phosphonitryl
Chloride,/
PERIODICAL: Doklady Akademii nauk SSSR, 1960, Vol 131, Nr 5, pp 1106-1108 (USSR)
TEXT: The authors investigated the possibility to synthetize the butyl
phosphonitryl ether by radiation of a mixture consisting of tetrameric. phospho-
nitryl chloride and a-butyl alcohol with a high-energy electron flux at room
temperature. An electron accelerator giving up to 1.0-1.2 Mev (Ref 14) was used
as the radiation source. The solutions were irradiated in glass cells equipped
with a thin glass utembrane. n-Butyl alcohol was cooled and stirred with air
saturated with n-butanol vapor. The course of the reaction was checked with an
Ostwalld viscosimeter and by checking the chlorine content in the resulting
compounds. It was found that, for both chlorine atoms in tetrameric phospho-
nitryl chloride, butoxy radicals are substituted. Then, the authors described a
typical experiment in order to obtain butyl phosphonitryl ether. With radiation
using 0.6 Mev electrons and a current of 3/Aa in the solution for six hours and
with an integral dose of 1-5-10 22 ev/ml at a maximum temperature of 300, a

viscous brown liquid with a disagreeable smell remained, when n-butanol had been
distilled off. Its aaalytical data corresponded to phosphonitryl ether of
n-butyl alcohol. The yield was nearly twice as much as compared to the yields,
obtained with methods according to reference 9, i *e. 45%. Table 1 shows the
results of viscosity measurements of the irradiated 5% solutions of the tetramer
in n-butyl alcohol as well as of chlorine determinations in the products obtained.
Figure 1 shows the characteristic changes of viscosity of a 5% solution of the
tetramer in butanol as a function of the integral radiation dose. The authors
come to the conclusion that the character of the radiolytic reaction mentioned
--s complicated. The rapid decrease of the chlorine content and the reduction of
viscosity at the very beginning of radiation are probably due to a substitutional
chain reaction. The substance dissolved is probably exposed chiefly to the
action of hydrogen atoms forming when n-butyl alcohol is being radiolyzed. By
reaction with atomic hydrogen, the ring of the tetramer is split. Mono- and
dimeric radicals are formed, and chlorine atoms are split off as HC1 (see schemes
(1) - (5)). Hydrogen atoms resulting from the reactions (4) and (5) react again
with the tetramer, and so on. If radiation is further prolonged, an inverse
reaction between HC1 and the butoxy derivatives due to a high HU concentration
is possible, besides ring formation (Table 1). For this reason, a maximum

appears on the curve (Fig 1); the second minimum is apparently due to the
suppression of the inverse reaction. The method mentioned in the title has
several advantages as compared to current-type procedures. When a 2% solution
of phosphonitryl chloride trimer inabsolute dioxane was irradiated, (pNclc 4H8 02)X
- a substitution product of one dioxane molecule for one chlorine atom of phos-
phonitryl chloride - was obtained (Table 2). This compound is highly resistant
to hydrolysis. Its structure is being further studied. There are 1 figure,
2 tables, and 14 references, 3 of which are Soviet.

the chloroplatinites, 145-1500C for the other compounds), at which no
decompodition as yet occurs w1thout irradiation. The metallic platinum separated
as a result of irradiation was gravimetrically determined. Table 2 gives the
initial metallic platinum yield in atoms/100 ev for the individual compounds.

25 h. In the case of preparations with 9-20 millicuries/g the concentra-
tion of the dissolved BaSO increased proportionally with time. The

solubility of Baso 4 is increased by an excess of Na 2 so 41 but especially
by an excess of BaCl 2 (Fig. 2). If inste7ad of Na2 io4a 0.1 N H 2~04 is
used for the production of Ba;O 49 solubility decreases (Figs. 3,4), but
the kinetics of solubility shows the same phenomena as represented in
Fig. 1. The authors explain this phenomena as being due to P-radiation,
by which the electric double layer at the interface is influenced. This
influence acts in a similar way on the dissolution as the ion strength of
the solution. The occurrence of a maximum is ascribed to a change in the
interaction between P-particles and the substance with an increased number
of P-particles. There are 4 figures and 14 references: 9 Soviet, 1 Austrian,

TITLE: Study of the Formation of Complex Compounds of Some
a-Hydroxy Acids With Yttrium and Cerium
PERIODICAL: Doklady Akademii nauk SSSR, 1q,60, Vol. 133, No- 3,
pp. 613 - 616
TEXT: The compounds mentioned in the.title are used in the chromato-
graphic separation of mixtures of rare-earth elements (Refs. 1-3). Data
required to find the optimum structure and composition of the hydroxyacid
used are not given in publications, however. The authors studied the
subject mentioned in the title using microamounts of yttrium and cerium
without carriers. They used aliphatic a-hydroxy acidalcontaining various
numbers of carbon atoms, such as glycolic, lactic, a-hydroxy isobutyric,
a-hydroxy isovaleric, and a-hydroxy isovaproic acid. A AY-2 (KU-2) type
cationite was used as the solid phase. The specific activity of the
working solutions containing Y91 or Ce144 was about 6000 count per 3+
minute/mi. In order to establish the distribution coefficient ;,Of Y

and Ce 3+ between the resin and the solution under static conditions,
the radioactivity in the original solution and in the same solution was
measured after equilibrium with the resin had been attained. The ionite
was used in the Na form. The coefficient f was calculated from the equa-
tion T = xv/cm with x being the residual activity in the resin, c the
residual activity in the solution, v the volume of the solution in ml,
and m the weighed portion of the air-dry sample. The experiments were
carried out at 20 10C. Fig. 1 shows the (log T- log A-]) curves which
were obtained by plotting the results achieved in the diagram EA-]
(concentration of the added ion). The values of To (i.e. cf for a zero
concentration of the added ion) are: 18 160 + 1200 for yttrium, and
26 170 + 2000for cerium. The stability const7ants of the complex com-
pounds were calculated according to S. Fronaeus (Ref- 7). f for the
three types of complex compounds assumed to exist is calculated from
eqPtion (1). The total stability constants of these complex compounds
MA + , MA+, and Ma --Viz. PI, P., and P may be calculated from equa-

tion (2). Fig. 2 shows an example of such calculations for sodium
a-hydroxy isobutyrate. Based on values found in this manner, the authors
Card 2/3

calculated the content of various forms of complex compounds as a func-
tion of the concentr 'ation of the substance to be added (Figo 3)- Similar-
ly, data on the stability constants of the complex compounds of Y and Ce
with the acids listed above were found (Table 1). Data obtained are simi-
lar to those which are given in publications (V. I. Paramonova, Ref. 9).
From their results, the authors conclude that the strength of the bond of
the hydrogen ion to the acid radical in the series of monobasic a-hy-
droxy acids, is proportional to the strength of the ionic bond of rare-
earth elements in complex compounds which are formed by these acids.
Fig. 4 gives additional data on a-hydroxy isocaproic acid. From these,
the importance of the volume factor of the added substance can be seen.
The authors found that a-hydroxy isobutyric acid is the best eluting
agent. A somewhat improved separation can be expected, by using a-hy-
droxy isovaleric acid. There are 4 figures, I table, and 11 references:

TEXT: The radiochemical stability of solutions of chloro-9 hydroxy-, and
chlorohydroxy-substituted complex compounds of platinum was investigated.
The least stable compounds were found to be those having the trans-
coordinate OH-Pt-Cl. Under radiolysis these compounds were completely
reduced to the metal. Radiolysis of aqueous solutions of PdCl 2 and VdCl 4
tends toward the complete reduction of Pd 2+ to the metal. Metallic Pd has
an inhibiting effect on the reduction process. Investigation of the
,catalytic activity of platinum blacks in the low-temperature hydrogenation
of cyclohexane showed that a black produced by the radiation method has
4 to 5 times higher activity than those produced by the Zelinskiy method
Of reduction., ThiZ is not the case with Pd.

PERIODICAL: Izvestiya Akademii nauk SSSR. Otdeleniye khimicheskikh nauk,
no. 4, 1961, 565-571
TEXT: There are no data available on the effect of the proper radio-
active radiation of solids on their catalytic properties. The authors of
the present paper investigated the change of catalytic activity as a
result of decay of the radioactive isotope, furthermore whether also the
A-radiation of a foreign element affects the reaction to be studied, and
the effect of irradiating the catalyst by a fast electron beam. The effect
of the radioactive catalysts CaCl 2' M95041 and Na2soV containing the
P-emitters S35 and Ca45, on the dehydration of cyclohexanol was studied.
The increased catalytic activity of radioactive catalysts, contrary to

non-labeled catalysts, which had been previously observed by the authors,.
was confirmed in many cases. The catalytic activity decreases with
decreasing radioactivity of the catalyst owing to decay of the isotopes
S35 and Ca45. Bombardment of the surface of the non'labeled catalyst with
800,-kev electrons has no pronounced effect, contrary to the effect of
P-particles of labeled S35 and Ca45 which are constituents of the catalyst.
Thus not only the labeled S35, but also the labeled Ca.45 increases the
catalytic activity of magnesium sulfate in the dehydration of cyclohexanol.
The radioactive isotope need not be a component of the acting catalyst.
It must be concluded that the increased activity of the radioactive
catalysts studied is due to a continuous bombardment of the active centers
of the catalyst with P-particles. The latter transfer their energy to the
adsorbed cyclohexanol molecules and reduce the activation energy of the
chemical reaction. It may be concluded from the decrease of the catalytic
activity due to the decay of the isotope in the catalyst that the new
elements resulting in the radioactive conversion do not increase the
activity. Apparently, the activation of the catalyst surface takes place
