ABSTRACT: In this report, presented at the Seventh All-Union
Conference on the chemistry of complex compounds hold
on 10th October, 1956, the author describes some previous
work on hateropoly and similar compounds and describes an
investigation in which tracer atoms were -used to study the
first stages in the formation of phosphotungstates.
Solutions of Na2HP04, Na2W04 or their mixtures, marked
with radioactive indicatorso were poured into capillaries
with sealed bottoms, these then being immersed in a
solution of exactly the same composition but without
radioactive isotopes. From the change in the concentra-
tion of tracer atoms in the capillary diffusion
Card 1/3 coefficients for the anions studied were calculated.

One of the authors expressed the opinion that in the

hydroxonium, tungstates and molecules of turgatic acid
play an important part. They interact in the solution
due to the. farjuLtion of hydrogen bonds. The water plays

employed. After boiling the ipoleoular weight of the
anions sinks to 1~00-1600, that is practically by half.
This phenomenon is described by an equation. Evaporation
leads to the formation of crystalline paratungstate
which again exhibits a double molecular weight in the
solution. On acidification of a Na 2Wo4-solution by
HNO the composition of the resulting anions depends
on 1he PH and on the duration of reaction. It is only
in the case Of PH 7,0-696 that hexatungstate ions
develop immediately. At PH 693-6,1 first develop ions
with 'a molecular weight of 5.000 - 10..000. After.10 days
it decreases to 1500. There probably*o'ocurs a desagre-
gation of the high-moleoular ions which first developed.
At PH 5,8-596 the molecular weight at the beginning
rises to the enormous height of 55-000 - 120-000, in
order decrease to 14-000 after 10 days. This would cor-
respond to sodium tungstate polynerized,about 12-fold.
The results of the polardgraphio investigation confirm
the above-mentioned transformations. The hexatungstate
ion is in its structure apparently related to metatunge4a-
te. Perhaps it its structural part(unit). The kinetics

Freshly prepared sodium-paratungstate solutions give

245-260 mtb. This maximum increases with tin* and

ABSTRACT: After a survey of publicatioRis (Refs 1-5) the authors say
that all elements of the Vit side-subgroup of the periodic
law of D.I.Mendeleyev are able to form oxy-compounds which
contain a h1e02+ -radical. Owing to the similarity of the
2
structure and several properties of the oxychlorides of
chromium: molybdenum, tungsten, and uranium it may be assumed
that this subgroup of elements is able to form complexes with
Schiff (Shiff) bases. Preliminary experiments have shown that
the intra-complex compounds may be obtained only by means of
molybdenum oxychloride. 8--oxyquinoline and several of its 2-
Card 1/3 derivatives form stable intra-complex compounds with the MoG,

ABSTRACT; The authors performed a thorough investigation of the
structure of the pyrosulfates of alkali metals with the
radioactive indicator s35, especially the investigation of
the equivalence of the sulfur atoms in sulphurous anions.
For the investigation of the exchange of the sulfur isotopes
in pyrosulfates preparations were produced by rapid melting
of normal sulfates with SO under atmospheric pressure. The
exchange of the sulfur isoiopes between radioactive sulfate
and SO takes place in the moment of the formation of pyro-
sulfata. In the pyrosulfates of lithium and sodium the loss
of activity in the sulfates during the exchange of sulfur
by SO amounts to 30-35%. The radioactive sulfates of
Card 1/3 lithiam and sodium do not enter into an isotope exchange

with SO, at loo 0C. In the case of the pyrosulfates of
potaani~m, rubidium and caesium the loss of activity of the
sulfates by an exchange of sulfur with 60 amounts to 50-554,-
The investigations show that in lithium p~rosulfate an
equal distribution of s35 takes place. In the pyrosulfates
of sodium, potassium, rubidium and caesium an enrichment of
s35 takes place in the residue of the normal sulfate, which
indicates an irregular distribution of the sulfur atoms.
Mereover it follows from these results that the normal
sulfates of sodium, rubidium and caesium in the reaction
with SO form compounds in which the two sulfur atoms are
not equivalent. The degree of exchange of the sulfur atoms
in the pyrosulfates to be investigated decreases in the
order Li 2S 0 --4 Cs S20 . This difference is probably due
to the de~~Ze in tKe pharizing action of the ions in the
order Li+ ---). Cs+. Thg obtained experimental values for the
exchange of the sulfur isotopes in pyrosulfates of the
alkali elements confirm the assumption of an existence of
isomeric pyrosulfc-tes with the following structure:
Lie 30 SO and Me (S 0 ). There are 1 figure, 8 tables, and

ABSTRACT: The solubility of calcium molybdate in the case of additions
of the chlorides and sulfates of sodium were investigated. No
noticeable increase of the solubility occurs at low concen-
trations of NaCl and Na 2so4 (0,001-0,01 N). With the increase
of the concentration of the salts mentioned above to 0,1 N a
considerable increase of the solubility of calcium molyodate
occurs. The solubility further increases with an increase in
the concentration from 0,5 to 1 N. Sodium sulfate solution
because of its considerable ionic force, with otherwise equal
concentrations, exerts the greatest effect on the solubility
of calcium molybdate. The activity coefficient of the ions

ABSTRACT: The presence of hydroxonium ions in phosphotungstic acid was
investigated by the method of isomorphous exchange by means of
radioactive indicators. Since the potassium ion has nearly the
same Lon radius as the hydroxonium ion, it was used as hydro-
xonium exchange-ion H 30+ has a ion radius of 1,33 1, whereas K+
has one of 1,35 X. An analysis was carried out of the action
exercised by the concentration of nitric acid and hydrochloric
acid on the potassium content of the precipitate of phospho-
L'un6stic acid. It follows from radiometric analyses that in the
range analyzed an uninterrupted series of solid solutions is
formed by phosphotungstic acid and potassium phosphorus tun.-state.
The results obtained show that phosphotungstic acid must be re-

ABSTRACT: The authors investigated in detail the influence of the pH of
the medium upon the velocity of exchange of inner addenda
between phosphoro-tungstic and sili,~o-tungstic acids. W185
isotopes were used in the investiga;ions. In acid medium (pH-2)
the exchange at room temperature is independent of the time
and a~mounts to about 20%. At boiling temperature the exchange
increases to 30% after three hours and to 50% after 16 hours.
in weakly acid medium (PH-4) the exchange is complete. In
almost neutral solutions the exchange is 40%, although this
reaches 80% at the boiling temperature. The velocity of the
exchange apparently depends upon two factors, the degree of'
hydrolysis of the heteropoly anions and the nature of the
Card 1/2 tungstate ions formed.

ABSTRACT: MoO , which was irradiated in a research reactor for 70 days by
a nLtron flow of 2,5 - 1013 rVcm2.sec, served as initial material
for the production of technetium. The irradiated preparation was
stored for I - 3 years so that the activities produced at the
same time died down completely.
Separation took place with M9HPO4-3H 30 and MONT04-005 H~O-
The separation is based upon ihe co-preoipitation of technetium
with difficultly soluble phosphates. After precipitation the
precipitant was chromatographioally purified. By the method
elaborated and tested by laboratory experiments it was possible
to separate milligrams of technetium. 2W 9 of M003 which, as
described, was irradiated, yielded 0,5 mg Tc99. Identification
of To" took place speotroanalytically and by measuring the ab-

and extended duration of calcination over more than 1-2 hours
does not exercise any influence upon the degree of fixation of
SrB9190 in montmorillonite. Activity, which can be washed out
by river- or sea water, amounts to "2%.
It is assumed that already before the crystal lattice begins
to change (T = 8000C) fixation is brought about by the forma-
tion of difficultly soluble strontium compounds with the ab-
sorber. Above 8000C the modificatiorsof the crystal lattice
structure and the step-like vitrification of the material be-
come effective. There are 7 figures, 1 table, and 19 refer-

sufficient intensity influences its catalytic activity and the
activation energy of the process. The increase in catalytic ac-
tivity apparently is connected with the increase in -the number
of active centers which form due to the defects in the crystal

on the effect of the ~-particles on the catalytically active

ABSTRACT: According to Jander (Ref 1) an anion of the aquopoly compound
forms on the acidification of solutions containing salts of
acids forming heteropoly compounds; Spitsyn and Koneva
(Refs 2, 3) carried out corresponding investigations of sodium
phosphate-tungstenate mixtures from which could be concluded
that an interaction between the ions takes place already in
the alkaline medium. In order to check the laiter the authors
investigated in the present paper sodium phosphate and normal
sodium tungstenate by means of the method of self-diffusion
using isotopes p32 and W185. The technique of determination
Card 1/3 is similar to that elaborated by Anderson and Saddington

The Application of the Self-Diffusion Method for Investigating the Formation
Mechanism of Heteropoly Compounds
(Ref 4); the authors used an arrangement the diagram of
which is given. The diffusion coefficient was calculated
according to an equation and the results are mentioned in
a table. It can be seezi that.at a plf of about 9 the diffusion
coefficient of the phosphate ion exceeds that of the tung-
stenate ion almost three times, while at a pH = 6 - 8 an ab-
rupt change of the diffusibility of the ions takes place.
Already in the weakly alkaline medium the addition of tung-
stenate changes the magnitude of the diffusion coefficient
of the phosphate ions, so that in mixtures the self-diffusion
of phosphate ions approaches the magnitudes characteristic
for tungstenate ions, and at P11 = 7,8 (as shown by isotope
marking) practically the same values are obtained for phosphonm
and. tungsten. A method of operation was used which in prin-
ciple is analogous to that by Spitsyn and Koneva (Ref.3). At
a pH below 8,4 a process of complex formation takes place
which does not prove the assumption by Jander. From the
diagram of the ionic weights can be seen that an area with
a mass close to that of W...2 is present, as well as one con-

acidous the medium must be , order to reach the same dif-
fusion coefficient. There are 4 figures, 4 tables, and 5

ABSTRACT: individual authors (referencea 1-8) ascribe different structures to
the niobates and tantalates-. In several cases the part played by the
water and the position of the water are not taken into account. All
pertinent papers except references 9,1o deal witt the character of the

by Spitsyn, Aistova and Vasiltyev (reference 12) the method of isoto-
pic exchange which was also employed by the authors in the present
paper was employed in the investigation of another binding. In the
tests they used water enriched with 018(1,2,S atom-0/o 011). The ex-
change was carried out at 950C in saturated solutions of these salts;
sodium-penta- and -hexa-tantalate,, as well as potasgium-hexa- and

ABSTRACT: Some recent investigations used the irradiation by y-rays
or neutrons for the influencing of the processes of hetero-
U
geneous catalysis. In the present paper,, however, the catalyst
itself is used as a source of the ionizing radiation for the
hetero.-eneous catalysis of gaseous substances. This cata-
lyst contained various quantities of the radioactive iso-
tope (0-radiator). It is assumed that the continuous bom-
bardment by P-particles will energetically influence the
processes which occur on the boundary solid.body-gas. There

of the catalvzer (especially a chan.~e of the properties
of its surface ) and a radiation-chem-ical influence of
radiation on the Easeous reagents even before their

was the catalytic dehydration of cyclohexanol over the
sulphates of magnesium and sodium, in which the sulphur
was subst i~ uted by various quantities of radioactive
sulphur,S . The investigation was carried out by
means of a catalytic apparatus of.the flowing type with an
inserted reactor. This anDaratus was placed in a tubular furnace
with aUtomatic feeding., The radioactive preparations MgSO4
and the measurement of the radioactivity of the catalysts
are then discussgi-No gaseous products viere generated by this
reaction,, The apparatus did not indicate the presence of
any radioactive contami=ts,. The more nori-radioactive
sodium sulphate is added to the magnesium sulphate , the
more does catalytic activity decrease. Also anhyd-rous sodium
suIT)-ate is a cat--lyzer for the dehydr,-;'tion of cyclohexanol,
Card 2/4 althouCh it is rather less active than nar'nesiun, sulphate.

The degree -/Iof the conversion of cyclohexanol into
cyclohexene increases with an increase of the radioactivity
of thqcatalyst, but these increases are not proportional
which respect to one another. The Arrhenius (Arrenius)
equation can be applied to the cases discussed in this
paper. The paper showed experimentally that the radio-
active radiation of the catalyst has an influence on cata-
lytic activity and on activation energy. Finally, some
possible explanations of the results of this paper are
discussed. The discussed phenomena are a completely new
effect of simultaneous action of the electrons and active
centers of the catalyst. It may be assumed that the P-
particles act upon the catalytically active centers which
had adsorbed cyclohexanol molecules, The P-pa:Aicles
diminish the activation energy of the dehydration of
cyclohexanol, Investigations are being continued. There

pounds are between 1,76 and 1,80 mv. If the oxygen
atom takes as a rule a --ingle place in the coordination
system the coordination number of vanadium is not s i x
but f i v e in these compounds. This is in contrast
to reference 2. The a3sumption that the vanadium ion
lies in the base of a tetragonal pyramid is more likely
to be right. This is proved by the fact that V'in'vanadyl-

ABSTRACT: The authors of the present report investigate the influence
of radioactivity on the sorptive properties of solids.
Barium sulfate, which had already previously been thoroughly
investigated (Refs 6, 7, 8), was used as a sorbent. The
present paper deals with the adsorption from aqueous solutions
of acid orange dye (Orange AT2B (C 16H11 04if2S)Na and of two
basic dyes methylene-blue (C.,6 if 18N3S)Cl and brilliant green
(C 27H35N2)C11 occurring on these sorbents. S 35 0 vihich was
introduced into the barium sulfatB during its precipitation,
served as a source of radioactive radiation. The production
Card 1/4 of the BaSO 4-preparations is described in short. 3 g of the

precipitate to be investigated was shaken at a temperature
of (25 � 0-5)o for four hours with 15 ml of the coloring
substance solution of the corresponding concentration. After
this, the coloring substance content in the liquid phase
was spectrophotometrically determined by means cf Lhe
apparatus SF-4 and SF-21,1. 1.1easurina errors amounted to
3-4~- The results obtained by these inveotigations are shown
by three diagrams. The acid orange dye is to the largest
extent adsorbed b~- the BaSO , viz. by one order of magnitude
more than the other colorin4,, agents. 1-ilethylene-blue is ad-
sorbed somewhat more than brilliantt green. The sorption
of the two basic coloring substances diminishes with increas-
ing speclf1c radioactivity of the barium sulfate. Thus, the
sorption capacity for methylene-blue at activities of
0.01 - 10 millicurie/9 depends linearly on the logarithm of
the specific activity of BaSO 4' The authors alsocarried
out special investigations for the purpose of solving_- the

investigated basic coloring substances is only imagination,
and whether it is not due to loss of color under the in-
fluence of radiation. Also these experiments are described
in short. According to the results obtained the variation
of the sorDtion of coloring substances is not due to destruc-
tion of these substances by the action of s35 radiation.
i'Joreover, no visible chemical or radio-chemical changes
co~.Jd be observed in the liquid phase that might have exer-
cised any influence upon the stability of colorin.- substances
or upon the intensity of their sorption. According to the
authors' opinion, the variation of the sorption of coloring
substances observed may be connected with the occurrence of
a positive charge on the precipitate of the radioactive barium
sulfate (in consequence of the continuous P-radiation).
There are 4 figures, 1 table, and 8 references, 3 of which

ABSTRACT: The resolutions of the XXI' t Congress of the CPSS demand an
intensive development of inorganic chemistry. Above all, the
production of inorganic synthetic polymerization substances
is demanded. It is necessary to establish theoretical bases
for the explanation of the condensation of the metal hydroxides#
the production of heteropoly acids, polysilicates, and poly-
phosphates. In the forthcoming Seven-year Plan a systematic
intensification in the investigation of the individual chemi-
cal elements of the periodic law is demanded. The investigation
of theelements of the rare earths and of the rare elements
is suggested, above all the production of purest metals,
oxides, and other compounds of the rare elements. The complex

is to be further developed. The experimental work for the
production of highly temperature-stable materials is con-
tinued. The technology and economy of the production of
nitric acid, sulphur, and phosphoric acid are to be improved.
A further development of the production of mineral salts,
and the production of potassium, magnesium, and boron is
demanded. `he Seven-year Plan calls upon the Russian inorganic
chemists to a responsible cooperation.

TITLE: Investigation of the Isotopic Bxchange of Tungsten in Sodium-

ABSTRACT: The isotopic exchange of the tungsten atoms in the tungsten
bronzes was investigated by means of the radioactive isotope
W165 (T 1/2 - 73.2 days). Sodium-tungsten bronzes were produced
according to the method of 0. Brunner. The results showed
that the tungsten atoms in the sodium-tungsten bronzes are
equivalent. The investigation results of the yellow and purple
tungsten bronzes are given in tables 1 and 2. The synthesis
of the tungsten bronzes from NaWO 4 and low tungsten oxides
was carried out in the vacuum furnace (construction given in
figure 1). The formulas NaWO3 or Ila2O.W205are suggested for
the golden yellow tungsten bronzes. The formula Na 20.W3 08
