Abstract : By fustbility, electric conducttVity and density methods were investigated
the sybtems Tl C12-ZnSO4 (I), Tl.,,Br2-ZnSO4 (11), T1212-ZnSO4 (III) and
Cs ' ZnSO ;Fl), constituting 3isgonal sections of mutual systems. De-
tefmined were compound TlCl-ZnS04 undergoes congruent fusion at 4400, eu-
tectic at 28& and 39.52% ZnS04- In systems II and III were found knini-
tes TlBr.ZnS04 and Tll.ZDS04 melting with decomposition, respectively at
438 and 4800. In system IV was found compound CeBr.MS041 underEping
congruent fusion at 502P, eutectic at 42CP mid 50% ZnS04-
Molecular volumes and atomic concentrations were calculated. On property
isotherms were detected in the proximity of composition of kainit'Ga mini-
ma and breakE of curves somewhat displaced from ordinate of compound com-
position.

TITLE: diat1`onoE-Aqueous Solutions of Sodium
Diethyldithiocarbamate (Doystviye 7-izlucheniya na vodnyye
rastvory dietilditiokarbamata natriya)

(USSR)
ABSTRACT: In the present work the action of y-radiations of Co 6o Wa&
investigated, ujing the formation of colored complex salts
of the substance mentioned in the title. The trihydrate
(C H )2 Ncs.,)Na;3 H20 was used as analytical reagent with a
spic.Mphotbme er of the type SF -2M as well as the apparatus
MP .,Cr,,.5 and G 0,'P-400 being used. From the obtained ex-
perimental data it could not be found which molecule par-
ticles of the Na-diethy1dithiocarbamate attack free radicals
forming in the radiolysia in water. In the hydrogen atmosphere
only 11--atoms can react with the molecules of the complex
former, while the lose of complex forming properties can be
Card 1/2 explained by a deposition of 11--atoms to the C-S binding,

76-32-5-43/47
Tho Action of y.-Radiation on Aqueous Solutions of Sodium Dieth,71dithio-
carbamate
forming .-SH groups- The OH.-radicals react with the molecules
in nitrogen and oxygen atmosphere. Different from the radio-
lysis of thiourea it was observed that in the pre3ent case
the radiolysis does not depend on the quantity of th(! dosage,
buqthat there is present a noticeable dependence on the con-
centration, which fact is explained by the rather groat ef-
ficiency of the chain cleavage of the molecules. The observa-
tion of the green thiuram coloring points at seconda:vy re-
actions taking place. Finally the authors thank Professor
11. A. Bak-h for his interest in this work. There are I figure,
1 table, and 8 references, I of which is Soviet.

ABSTRACT% Reported at the meeting of the radiochemi3try and
Isotope chemistry section of the VIII Mendeleev
Conference on General and Applied Chemistry. Li uid
benzene was Irradiated with accelerated (800 kevi
electrons in a molybdenum-glass compartment, which
was connected to a 1-cm quartz cell. Ultraviolet
spectra of the radiolysis products, shown in Fig. 1,
were obtained on the SF-4 spectrophotometer.

TITLE: Trends of radiation-chemiatry development
PERIODICAL: Vestnik Akademii nauk SSSR, no, 1. 1961, 116-iiq
TEXT: The Second All-Union Conference on Radiation Chemistry was held
in Moscow from October 10 to 14, 1960. It was conveaed by the
Otdeleniye khimicheskikh nauk Akademii nauk SSSR (Department of Chemical
Sciences of the Academy of Sciences USSR) as well as the Gosudarstvennyy
komitet Soveta Ministrov SSSR po khimii (State Committee for Chemistry
of the Council of Ministers of the USSR). The Conference dealt with the
discusnion of theoretical problems of radiation chemistry of aqueous
solutions, organic substances, high-molecular compounds, and solid
substances. Phenomena taking place in the systems mentioned under the
effect of ioniaing radiation play an important role in nuclear engineer-
ing and radiobiology. The present state of the problem of primary
processes and the mechanism of radiation-chemical reactions was checked

specially. For the first time it was endeavored to outline the statistic-
al theory of activation processes in condensated bodies, which proceed
in the field of ionizing radiation, as well as to utilize the theory of
the repeated dispersion of electrons in the substance for studying the
mechanism of radiolysis. Problems of energy migration in condensated
systems were discussed, In accordance with the radical-diffusion theory
of the water radiolysis, the OH radicals and H atoms developing in places
of high ionization density are to be considered as being primary
products of the water radiolysis. A still simpler model of radiolysis
was proposed for the field of dilute solutions. The data mentioned at
the Conference, which refer to the radiolysis of the solutions of H2029
2+ 3+ 2
021 H2 , Fe , Fe , NO 3-' C'03-' S04 _' the neptunium salts and uranium
salts, agree well with the model mentioned. Concepts on the role of
excited water molecules in the process of radiolysis were takLn into
consideration in a number of reports, specially those concerning the
aqueous solutions of organic compounds, in order to clarify experimental
results. Problems of radiation-electrochemical processes in aqueous
solutions were discussed in detail. The studies of reactions cf the

radiation-chemical synthesis may be described as being a trend
of radiation chemistry. The initiating of chain reLctiot-.s 'L.`-,rou,h t*-:e
effect of ionizing radiation constitutes an independent problem. The
conduction of radiolytic oxidation at various temperatures permits
demarcation of tho area of the non-chain- radical-reaction course and
the area of a chain process. The studies of the sensitizer effect of
the solid phase on the radiolysis process are given special mention.
Radiation polymerization and the effect of radiation on polymers for
the purpose of their modification represent the main problems of the
radiation chemistry of polymeric materials. Studies were conducted
regarding the effect of different parameters on the radiation polymeriza/
tion of low-molecular monoolefins, acetylene hydrocarbons, trifluoro
ethylene, tetrafluoro ethylene, allyl silane., phosphonitryl chlcride.
The stabilizing effect of the organozinc compounds on the heat resistance
of the irradiated polyethylene was shown next. The majority of the
studies for the investigation of unstable intermediate products of
radiolysis was done either with -frozen hydrocarbons or with polymers,
-the measurements of the spectra of the electron-paramagnetic resonance
proving to be most useful. 'New types of electron accelerators specially

built for purposes of radiation-chemintry and distinguiahed by very high
voltages at relatively low current energies are described as being very
promising. Finally, it is stated that the volume of research in all
fields of radiation chemistry has greatly increased during the laot
3-1/2 years since the previous conference. New fields of scienti:ic
studies (such as the chemical effect of radiation on solids and
heterogeneous systems) were created. The number of scientific
institutions occupied with research in the field of radiation chemistry
has greatly increased, also outside the scientific centers. Charicter-
istic for this period of time is the further use of physical investiga-
tion methods, primarily the e.p.r. which permits to gain insight into
the nature of short-lived intermediate products, developing under
radiation effect. The delegates to the Conference unanimously approved
the proposal by the Orgkomitet (organizing Committee) to convene a
.-,onference which would deal with individual theoretical problems of
radiation chemistry.
