Studied heat capacities of cis- and trans- isomers of platinum diamino-dichloride.
Eypected heat capacity of Peyrone chloride to be greater than that of the chloride of
Reiset's second base (the trans-isomer),, for the temperature range between absolute
zero and temperature of isomerization. However, they were iddntical. Concludes that,
for any temperature, difference in isobaric potentials of these substances, equal to
difference of their total energy.. is fully determined by the heating effect of the
isomerization reaction. Submitted 13 Jul 48.

Abstract By the method of periodic heating (R7.hKhim, 1956, 6358) in the interval
32-3940 C, heat capacity CP 01-' KN03 was determined (130 points). Deter-
mine,d were temperature of transformation (127.9 - 0-10C ), heat of trans-
formation (1918 ~_5 cal/mole), point of fusion (334.3-t-0-10C) and heat
of fusion (2300 Z 5 cal/mole). In the interval 25 - 6700K were calcu-
lated and tabulated the values of enthalpy, entropy and isobaric poten-
t'al; S298~16 = 31.72 entropy units.

TITLE: Adiabatic Calorimeter for the Determination of the Actual
Specific Heats of Substanoes of Low Thermal Conductivity /-Ik-
in the Range of 30-750 0o The Specific Heat of CorunflumiJ
PERIODICAL: Zhurnal neorganicheskoy khimiiq 1960, Vol- 5, No- 89
pp. 1641-1649
TEXT: The authors based their work upon a paper (Ref. 1) by the author
mentioned second who in 19J8 designed a calorimeter for temperatures
ranging between 30 and 400 C. This calorimeter could not be used for
higher temperatures, since its heat exchange then became too high. The
authors discuss the drop in temperature in substances of low thermal con-
ductivity, 0and describe a newly designed calorimeter for temperatures
between 25 and 7500C. The drop in temperature is kept low by way of the
small volume of the apparatus, and the low loss of heat along the conduct-
ing wires. Fig. 1 shows the cross section of an apparatus consisting of the
actual calorimeter, three shieldings for guaranteeing the adiabatic

condition, and a number of insulating covers made of stainless steel and
aluminum. The actual calorimeter is shown in Fig. 2; as compared to that
of 1948, it has remained unchanged. Heater and resistance thermometer are
similar to P. G. Strelkov's standard thermometer (Ref. 24). The three
shieldings are described in detail. They are cylindrical and contain heat-
ing elements made of nichrome bands (Fig. 5) wound round a quartz frame
work; they are regulated by means of PtRh (10%) - AuPd (40%)thermocouples.
The shielding layers consist of 0.1 mm platinum sheets, since silver prov-
ed to be unstable at temperatures over 7200C (Fig. 3), and 3 A IT (EYaIT)
steel delays the temperature balance (Fig. 4). Fig. 6 shows the circuit
for the temperature regulation of the shieldings. The temp ature is taken
by means of a platinum resistance thermometer and a Kn-48AKL-48) poten-
tiometer. The platinum resistance thermometer was calibrated at the triple
point of water, the boiling point of water, and, contrasting with the intei-
national scale, at the melting point of antimony instead of the boiling
point of sulfur. This deviation was compensated by comparison with the

standard resistance thermometer No. 124 of the laboratory. After the de-
termination of the heat value of the calorimeter, the stability of th6
thermometer indications was checked by measurement of the transformation
point of Na2so 46 10H20 (Table 1), and transformation and melting points
of KNOY The electric work was determined by means of a Raps compensator
of the workshops of the Vsesoyuznyy inatitut mer i standartov (All-Union
Institute of Measures and Standards), and a second counter. In the range of
3008 to 1 , the heat value of the calorimeter fluctuates by 5% (Fig,7)-
The temperature drop in the calorimeter was found to be at the transforma-
tion point 117-90C of KNO . In slow processes, the temperature threshold
is not reached. The lattel was computed according to M. A. Reshetnikov's
equation (Ref. 29), the applicability of which has been examined in a
previous paper (Ref. 22). Finally, the determination of the specific heat
of two samples of synthetic corundum is described, and their spectroscopic
data determined by V~ L. Ginzburg, are given, Table 2 shows that the
scattering of the measured values does not exceed + 0.5%. and the values

ABSTRACT: By hitherto known methods the distribution coefficients of
HNO3 and uranyl nitrate in solutions of nitric acid and so'~'.,.Adonz
of DAMPA (di-isoamy! esther of methyl-phospho-rffc ac-1d) izi
petroleum were determined 6n the basis cf he DAMPA-cont-sx',t

aqueous phase. It could be shown that, especially in the
aqueous phase, small uranium concentrations can be extrasted
with DAMPA considerably better than wit'" TBP (tributyl phosEhate).
The extraction mechanism develops according to the equation

PERIODICAL: Zhurnal neorganicheskoy khimii, 1960, Vol, 5, No- 10~

TEXT: The authors wanted to make a detailed study of the extraction of
U(VI) by means of solutions of tri-n.-octylamine (TOA) in o-xylene and
carbon tetrachloride. In an earlier paper (Ref. 10), it had been found
that in the presence of free nitric acid the entire TOA is contained in
the organic phase as TOA-HNO3. Therefore, the authors write down the
following equation for the extraction of uranium:
TOA.HNO U02+ + 2NO- (TOA.H)UO (NO (1). The
3 org 2 aqu 3 aqu 2 3 3 org
dependence of the distribution coefficients on the concentration of free
TOA.HNO3 in the organic phase was studied at concentrations of 4.3 and

5.4 mole/l HNO3 in the aqueous phase,, In this connection the fact that,
according to Ref. 10, the concentration of TOA.HNO3 varies in the organic
phase as a result of the reaction
H+ + NO - TOA~HNO [ITOA.HNO -.HN (5), was taken into
aqu 3 aqu t 3 org - - 31 03
account. By using o.-xylene as solvent the constant K3 of this reaction
was found to be 0.13. Table 1 gives the values for the distribution
ccefficient a, Fig. I shows that with K3 = 0.13 the distribution
coefficient a increases linearly with the concentration of TOA.HNO3. At
4.3 mole/1 HNO 3 aqvL and 0.470 mole/1 TOA.HNO 39 a is 1.81, at 5.4 mole/1
HN03 it is 2,50~ Fig. 2 shows a as a function of acidity of the aqueous
phase. a passes a maximum at 6 - 7 mole/' HN03. The decrease of a with
higher acid concentrations is explained by the formation of
I
~TOA.HN 03) HN03 and by the occurrence Of U02(NO3)5 ions. In Fig. 3 a is
represented as a function of [ITT in Fig- 4 as a function of the uranium
concentration. o-xylene and r,,arbon tetrachloride served as solvents. With
very ic-w uranium concentration in the aqueous phase a is almost independent

occurs, With high uranium concentrations a decreases.. This is explained
by the reduction of concentration of free TOA.HNO as a result of 'he
extraction process, in Fig, 5 the equilibrium dMribution of uranioum
between aqueous and organic phase is shown at 0.47 mole/1 TOA,HNO3,
dissolved in 0-C6H4(CH 3)2 or CC14. Table 2 gives the dependence of a on
the concentration of uranium in the aqueous phase and the values for the
stability constant K, of the_EomPleXA(TOA.H)UO2(NO3)3- These values were
suffil-iently constant only at uranium concentraticns in the organic phase
up to O~10 mole/l, They amounted to 2.02t0.12 for 0.47 mole/l TOA.HNO

solutions in TOA is shown in Fig. 6. It considerably differs from the
spectrum of uranyl nitrate., it is similar., however~ to the absorption
spectra of the trinitrate uranyl compounds. The optical density of

TITLE. The extraction of UVf -and UIV -with the di-isoamyl ether
of methyl phosphoric acid from HC1 solutions
PERIODICAL~ Radlokhimiya, i961, Vol.3, No.2, pp.129-136
TEXT. During the last few years di-isoamyl ether of methyl
phosphoric acid (DEDIPA) has been used as a satisfactory extracting
agent for uranium. The authors mention briefly their previ.ously
published results Pri the effectiveness of the compound and on the
stability of the hexa-valent uranium complex, extracted with DEMPA,
fLs rompared to the stability of the complex extracted with
tributyi phosphate (TBP). The present investi ation deals with
!."he reac-tion mechanism of extracting UVI and Uf# with DEMPA from
HC! ~~olutions; the stability of the uranium compounds, extracted
from the HC1 solutions with the two aforementioned reagents is
::ompared, Of ea '-h reagent 20%solutions, in carbon tetrachloride,
were used. D6*la--Iz of the preparation of uranyl chloride (U02C'2)
and of uranium tetra,.hloride (UC14) are given. Equal volumes of
the 2 phases (10 mi ea~~h) were used for the extraction process

equilibrium, The solution was allowed to settle for 18 hours
(UVI) and I hour (UIV) respectively; thereafter the phases were
sspar-ated, Each phase was analysed for its uranium content and
the dispersion ~oeffisient defined as the ratio of the
con~entrazion3 of the element in the organic and in thp aqueous
phase, During the extraction of hexavalent uranium it wa3 found
that UVI is extra~cted to an appreciable degree with a,20Vo solution
of' DEMPA in CC14 at acidities > 2N HC1. The tetravalent element
is ~x-rracted satisfactorily with 20% solutions of DEMPA and TBP in
CC14 only at concentrations of HU >4 -5 N HCl. The complex
UUZCJ-2.2-IjEMPA was formed in the investigated acidity rar.~Se (up to
5N HC1)~ tetravalent uranium forms the complexes UC14 ~2DEMPA and
UC14.2TBP. The ratios of the stability constants were calculated
for the complexes U02Cl2.2DEMPA and U02C12.2TBP (113 + 16) and for
the complexes UC14,2DEMPA and UC14.2TBP (approximately 300).

ABSTRACT: Chemically pure primary alcohols of normal structure were
used in the investigation; their properties did not differ from those
described in the literature. The tri-n-octylarnmonium nitrate was
obtained by the reaction of equivalent amounts of 99.5% HN03 and tri-n-
octylamine. The temperature measurements were made by the standard
method. Experimental resulte are shown In graphic form. It was found
that in the reaction of metbyl,~ ethyl, n-butyl, n-bexyl, n-octyl, and

ABSTRACT: Until recently no double crystal speotrcmeter existed in the USSR.
After the construction of the URS-50-I unit it was perfectioned by
the authors, so that it became possible to use it as a double
crystal spectrometer. The essential bases of a two-crystal spectro-
meter are here described in short. Satisfactory functioning of the
URS-50-I unit as a two-orystal spectrometer can be attained only by
very careful adjustment. The latter consists mainly in the follow-
ing- 1.) The rotation axis of the B crystal mil t coincide with its
plane of reflection. 2.) The axis of the B crystal must coincide
with the plane which is parallel to the reflecting plane of the
A crystal. A special theoretical investigation of the accuracy of
recordings of the two-crystal spectrometer ard of the influence
exercised ba-adjugtments upon accuracy was carried out. According

necessary in absorption spectram registration that at every point
of the spectrum intensity be measured twice: once with and once
without the absorber. Besides, a special device, by which the ab-
sorber is always returned to the same place, must be provided. This
method was improved by the authors by the introduction of an
additional control counter. Besides, it isproved that the entire
spectrum can be recorded by means of a constantly fixed absorber.
In this mamier the time of recording was considerably shortened.
