TEXT: The synthesis of the minerals was carried out by
fusing chemically pure bismuth, sulphur and selenium in an
evacuated quartz flask at 700-800 OC. The complete system from
Bi2S3 to B'2Se3 was covered. Cooling curves were drawn for all
the alloys using an electronic potentiometer type ~,Nn_oq
(EPP-09). From the results, the phase diagram was drawn (see
figure, x axis in mol.l'). X-ray powder photographs of several of
70
the alloys were also taken after homogenising. From the results
and also from a study of the literature, it is proposed that up
to 67 m0 '-1.'% B12Se3 the stable structure is of the bismuthine type.

With more than 80-85% B12Se3 the structure is the tetradymite type,
A sample of natural ore from Mexico was also examined. X-ray
photographs showed the same lines as those in the artificially
prepared sample but, in addition, lines corresponding to
guanajuatite were present. After a heat treatment the additional
lines disappeared, The X-ray investigations were carried out in
the Laboratoriya rentgenostrukturnogo analiza (Laboratory of
Structural Analysis by X-rays) of IMGRE under the direction of
Yu.A. Pyatenko. Acknowledgments are expressed to N.D.Sindeyeva

PERIODICAL,~ Doklady Akademii nauk SSSR, '1960, Vol, 134, 140~ 5,
PP. 1111-1114
TEXT3 The authors present a review of the production method by A~V.Grosse,
M. S,. Agruss (Ref. 7), which is based on the sorption on manganese
dioxide from nitric acid solutions. They worked out a purification method
fo= milligram amounts of Pa from impurities of niobium, titanium, and
zireonium which exceed the Pa content (1-2 mg) by the ten- and hundredfold.
The separation of these elements on anionites of USSR production AB-16
(AV-16), AB -17 (AV-17), and A H-2,~ (AN-2F) under the conditions described
in publications for Dowex-1, did not yield satisfactory results. The use
of manganese dioxide proved to be more efficient.. The chromatographic
sorption of Pa from a 10 N HN03 solution permits its separation from
large titanium and niobium quantities. These two elements can be fully
removed from the column by rinsing with 10 N HN03I As the behavior of

protactinium and niobium is similar under the given conditions, the
authors discussed the problem of their separation more thoroughly
(Table 1.). The use of acid NH4F solutions for the elution of Pa and Rb
permitted a complete separation of these elements when they were absorbed
in a column with manganese dioxides Fig. 1 shows the elution curve of
Pa-233 and Nb-95 with 0.5 N HN03 + 0.2 N NHO, The authors used the above
methcd for the concentration of Pa-231 in the precipitate of Zr-, Ti-,
and Nb phosphate. The phosphates were boiled with 10% NaOH solution ', and
the resulting hydroxides treated with HN03' The nitric acid solution was
passed through a column with manganese dioxide, and Ti and Zr were removed
with 10 N HN03' Protactinium was separated from niobium as stated above.
Ae the eluate contained some )Aglml of manganese, it was led through a
column with the resin Kj -2 (KU-2) where Mn was adsorbed, Thus, mill'-gram
quantities of Pa were obtained from some kilograms of initial concentrate.
Its !.hemiial purity was confirmed spectroacopically. Pa was additionally

TITLE Separation of protoactinium from zirconLum, titanium.

PERIODICAL: Radiolchimiya, v.4, no.1, 1962, 89-94
TEXTt The authors investigated purification of protoactinium
from the admixtures of niobium, titanium and zirconium using some
anion-exchanger resins and Mn02- The work was carried out with
Pa233._ The resins used were AB-16 (AV-16), AE-17 (AV-17) and
AH-.2() (AN-2F) in the Cl- form, Active MnO,) was prepared by the
generally accepted method described by Ye,V,,A!ekseyevskiy (Rtf~12)
The separations on the reBins were carried out in hydrochloric
acid solutions which were found to be the best for Dowex-1 resin
(Ref-8). 7NHC1 containing 0.9 mg/ml Zr and also indicator
quantities of Nb95 and Pa233 were passed through a column of
0.5 cm diameter, 9 cm high, filled with 40 to 60 mesh resin.
Solution flow was 0.2 ml/cm2/min, With resins AV-17 or AN-2F, ~it
was possible to separate 85 to 90% of Zr, which appeared in the
first portions of eluant, Nb appeared in the eluate only slightly

before Pa. For resin AV-16, Nb and Pa were eluted almost at the
same time, MnO2 was tried next for the separation of Nb and Pa,
The authors determined distribution coefficients of Nb and Pa
between Mn02 and O~5 N NH4F for a wide range of concentration s of
hydroxyl ions, The distribution coefficients %~iere found to
depend on these concentrations, The dependence was not ggreat at
PH < 3, but was marked for Nb at PH > 4, Thus the use of
concentrated NH4F solution as an eluent at the PH of 5-2 gives a
considerable degree of separation between Nb and Pa. 8 0% o f R
was eluted at the time of appearance of Nb in the eloate I t 1, a 's
found however, that an increase in temperature decreases the
degree of separation- To decrease undesirable hydralytt---
processes. the separation was carried out in the acid medium,
although it was expected that in neutral. solutions the separ3t ion
would be more complete, The number of theoretical plates for tht-
column and method used (0,5NFIN03 + 0,,2NNH4F solutiori u.-5ed as
eluent, Mn02 column height 35 cm, diameter OA crit rate of fl o%,~

from nitric acid solutions included a study of the possible use of
substandbs.which had never been used as carriers of that element
before, such as ion-exchange'resin hypopbosphate and certain oxides
that are not easily soluble in nitric acid. Protactinium can be
absorbed from nitric acid solutions by every tested sorbent. The
introduction of extraneous salts into the solution sharply reduces
the sorbents' capacity in regard to protactinium with the exception
of manganese dioxide. The sorbtion-of iron by manganese dioxide is

ABSTRACT: In order to determine the com:oosition and stability constants of nitrate
com.lexes of protactin the dependence of the distribution coefficient was studied
as a function of hydrogen lion and nitrate ion concentration during extraction of pro-
tactinium with tributyl phosphate. At a constant ionic strength of the aqueous v6se
9 5 and 6 in the range of high acid concentrations (3--6 IN)) the distribution cooffi-:~
cient was shown to be proportional to the square of the hydrogen ion concentration.
0'3 -
At the constant value P = 5, the distribution coefficient increases with the IN 1
concentration. A mechanism is proposed for the reaction of extraction of protactinium!
with tributyl phosphate. The stability constants of the nitrate conolexes
Pa(0H)2(NG~)2+, were calculated to
Pa(042(NC~)2+9 Fa(OH)2(NG3)30, P-id Pa(002W~)4-

ABSTRACT: The study has been carried out spectrophotometrically, as exacter
results can be achieved than Trith the lightfilter method. Examined
were the surfaces: of a wheat field, of green grass, of dried grass,
of black smoke and of a snow field at wave lengths of 4oo-85o MA-
With the wheat field the absorption band of the chlorophyl (65o-7oo
m,&.L) showed up, even better still with the green grass, whereas with
hay and the black smoke the spectral albedo rose monotonously, The
next.task will be the examination of a bigger range of surfaces as
well as the day's course of the spectral albedo.

TOPIC TAGS: meteorologicalobservation, temperature measurement, temperature inver-
sion, air humidity, ventilation engineering,
ABSTRACT: The authors evaluate an effect of forced ventilation in psychrometric
cabins based on the accuracy of the temperature and air humidity measurements carried
.out
in different regions. It is shown that the ventilation of psychrometric cabins
in regions with relatively moderate air temperature and a low number of calm days has
hardly any significant value. In regions with high temperatures, and weak winds,
the ventilation of cabins will supposedly improve the observation of air temperatures
and eliminate errors in determining air humidity caused by the application of standar
psychrometric charts. Orig. art. has; 2 figures and 2 tables. [Based on author's

ABSTRACTs In tests in which Yu.?. 'Jikhaylov participated (Ref 1), it
was discovered that magnosite-chromite bricks displayed the
greatest stability under the influence of slag (Fig 1). The
chemical composition of the raw materials is quoted in table
1 and the composition of the layers in table 2. In figure 2
the specific gravity of the samples with an addition of clay
are indicated and in figure 3 their permeability for gases.
Figure 4 shows their resistance to pressure. In the plant
"Magnezit" a series of sample stoppers (stopornyye trubki)
were made of magnesite-chromite, whose composition is given
in table 3. In table 4 the properties of these stoppers are
listed. The condition of magnesite-chromite stoppers after
treatment is shown for burned stoppers in figure 5 and in
Card 1/3 figure 6 for stoppers that were not burned. Conclusion;

Magnesite-Chromite Products for the Vacuum Treatment SOV/131-58-104'/11
of Transformer Steel in Teeming Ladles
unburnt magnesite-chromite material showed a satisfactory
hoat resistance when the samples were quickly heated up to
16800; the necessary density of the stoppers could not be
achieved through pneumatic stamping. In the vacuum treatment
in the ladle the burnt stcppers guaranteed an endurance period
of 25 minutes at temperatures up to 16600. Magnesite-chromite
bricks performed satisfactorily in vacuum in the ladle. Ac-
cording to data of the zavodskaya laboratoriya Verkh-
Ieetskogo zavoda i Ural'skogo instituts, chernykh metallov
(Laboratory of the Verkh-Isetsk Plant and the Ural Institute
for Ferrous Metals) the use of refractory magnesite-chromite
products for-the vacuum treatment in the teeming ladle has
brought about good results with respect to the properties of
the transformer steel.

PERIODICALs Ogneupory, no. 10, 1961, 456 - 461
TEXTt Kaolin of the poletayevskoye deposit near Chelyabinsk was tested
as to its suitability for the production of refractory materials. 410 t
of kaolin was mined for this purpose by the Miasskaya kompleksnaya
geologo-razvedochnaya partiya (Miass Comprehensive Group of Geological
Exploration). The following properties of the kaolin were determined;
53 - 81~ silicia acid, mostly >70%; 16 - 32% Al 2031 0.2 - 3.56% Fe2 03'
Heat resistance lies between -1630 and 17600C. The kaolin can easily be
concentrated by the wet process. In the concentrated kaolin, three types
are distinguishedi noncaking, light-colored (60/;-), caking (30~t), and non-
caking containing quartz (10 15P). The kaolin is coarsely disperse;
the sum of fractions below 5~ amounts to 57.1~-- Concentrated kaolin

TITLE: Some Cases of Reaclions f th Redistribution of Radicals in
Organic LeadliTin,'Iand. Compounds
PERIODICAL: Doklady Akademii nauk SSSR, ig6o, vol. 132, No. 2, pp. 364-366
TEXT: Heating of an asymmetric organometallic compound of type R3R'Pb with
catalytic amounts of aluminum chloride, causes the redistribution of the radi-
cals (Ref. 1). A dynamic equilibrium, and a mixture of all possible combinations
of tetraalkyl derivatives of the concerned metal develop. The authors intended
to investigate such cases of the above reaction in which the equilibrium is
disturbed, thus causing a clear deviation of the interrelations between the
reaction products from those occurring in general. The authors found out that
hexaethyl dimetalB are asymmetric, as for instance (C 2H 5)3Sn1l, R being (C2 H5)3Sn.
Assuming that the two radicals readily take part in their redistribution, the
following mixture necessarily must develop (according to publications):

(C2H5)4 Sn W, (C2H 5)3 SnR (II), (C2H5)2 SnR2(111), C2H5SnR3(IV), and SnR 4 M.
However, there will be no equilibrium in the developing mixture since (III),
(IV), and (V) are no "symmetrical" compounds. Theoretically it is therefore
probable that (III) _ (V) will enter into side reactions during the
redistribution of radicals, and besides tetraethyl tin will develop a series of
substances with chains of metal atoms still longer and more ramified. Due to the
decomposition of molecules, there will be no equilibrium in the mixture M - M.
In agreement with the above theory~ the authors found out that 2-3 weight%
of aluminum chloride or other catalysts of the radical redistribution, rapidly
reduce the stability of hexaethyl diplumbane and hexaethyl distannane, also
altering its decomposition mechanism (equations (B) and (V)). It was
spectroscopically proven however, that the,decomposition of these two compounds
takes place according to equation (B) developing an intermediate product of
diethyl lead, and diethyl tin respectively. During the disproportionation of
hexaethyl distannane (but not of hexaethyl diplumbane) however, highly-
molecular intermediate products develop between 700-750 under the influence of
A1013. This is in agreement with the above-mentioned reaction mechanism. In this
case the equilibrium is disturbed by the participation of reaction products in

side processes. This causes the formation of unstable products. The authors
give further examples of publications on their statement (Refs. 3-8). The
reaction between isopropylehloride and tetraethyl lead was not successful. Table 1
gives a summary of the authors' experiments. There are 1 table and 8 refer-
ences, 2 of which are Soviet.

Reaotiona-of aoyl peroxides with organic derivatives of
lead, tin, and silicon
Doklady Akademii nauk SSSR, v. 137, no. 3, 1961, 618-621
TEXT: The authors discuss and compare the reactions of benzoyl peroxide
(BF) and acetylbenzoyl peroxide (ABP) with organic derivatives of tin,
lead, and silicon without solvent and under exclusion of atmospheric
oxygen. They believe that the d-bond may be ruptured at the same time
according to two mechanisms in the case of the organotin compound;
1) via formation of an active complex, 2) via formation of kinetically
independent particles. In this way, the number of end products increases.
As the reactions discussed (Table 1) take place only at elevated temper-
atures, the authors assume that these reactions may be due to decomposition
of peroxides: C6H 5COOOCOR --r C6H5COO. + RCOO. (1), where R - C6H5 or CH 3;

C6 H5COO* ---'P'C6H5* + CO 2 (2). The latter, however, is of minor importance.
The resultant free benzoyloxy radicals react with organotin compounds,
with substitution of benzoate radicals for the ethyl radicals in the
latter: C6H 5C00- + (C 2H 5)3SnX --'* (C2 H5)2 SnX(OCOC6H5) + C2 H5' (3). Here
and henceforward, X - C 2 H5f Cl, Br, C 6H5COO. The results of experiments
1-4 indicate that the nature of X affects the course of (3) only little.
In the case X - Cl and Br, the authors isolated only diethyl tin
dibenzoate and diethyl tin dihalide, apparently owing to disproportionation:
2(C2 H5)2 SnX(OCOC 6H5) ---P' (C2H5)2SnX2 + (C2 H 5)Sn (OCOC6H 5)2 (4). The
free ethyl radicals resulting in (3) disproportionate and are slightly
dimerized: 2C2H5* -P. C2 H6 + C2 H4 (5); 2C2H 5 *-ts, n-C4H 10 (6). The
low total amount of gaseous hydrocarbons (less than 1 mole per mole of
decomposed peroxide; experiments 1-4) suggests that the ethyl radicals
initiate PB decomposition and give ethyl benzoate (experiment 4). In
this way, the authors explain the formation of all products confirmed on
the basis of a scheme of free-radical interaction. As, however,

the authors studieVthe:interaotion of ABP with tetraethyl tin and triethyl.,
tin chloride (experiments5 and 6).- They conclude from the resultant
reaction products that in this case t1le afore-mentioned modes (1 and
of homolytic rupture of the covalent bond occurred. The reaction'of BP
does not essentially differ from the
with tetraethyl lead (experiment
one discussed above. Here, (2) is almost insignificant. The reaction
of acyl peroxides with tetraethyl silane (experiments 6 and 9).Proceeds
quite differently; herepprocesaes of the kind of (3) and (8) are
missing, the Si-C bond being obviously stable to homolytic rupture. The'
initial stage of these reactions is assumed to be based upon decomposition
of acyl peroxides according tv (1), (2), and CH3COO- --i- CH 3* + C02 (9)'

The resultant free radicals remove the hydrogen from the tetraethyl silane

compounds 'with two or more silicon atoms in the molecule are formed by
recombination of the secondary radicals. 'They will be later described.

organosilicon compounds with peroxides being considerably different, the
authors studied the interaction of BP with the organdtin analog of tri-
methyl-phenyl silane (experiment 10). No gaseous hydrocarbons were
formed in this case and CO yield was low. The authors conclude from
this that (2) is only a sih reactiong and that no CH radicals are

the other hand, is-obtained in a high yield: (CH ) snoll + C H COOH

mainly the Si-H bond is cleft, giving triethyl silicon benzoate as the
most important silicon-containing product. In this case, apparently
also processes take place which remind of (3), since small quantities
of ethane, ethylene, and butane result. The authors continue their

ABSTRACT: The authors first mention some previous papers on this subject.
They investigated the interaction of triphony1chloroilothano
with ethyl lithium, the first act of which must be exothermic
if it proceeds accordina to the scheme. The reaction was car-
ried out in a thin-valled test tube which was placed in the
resonator of a EPR-spectrometor. In this reaction radicals
were actually observed. The byperfine spectrum of these radicals
exactly corresponds to the spectrum of absorption of triphenyl-
methyl radicals. .1 diagram shRs the kinetic curves for the varia-
tion of the concentration of triphenylmethyl radicals in the
0
course of the reaction at -44, -541 and -80 . In the first
instant of the reaction, the concentration has a distinctly
marked maximum anti it decreases behind this maximum. The des-
Card 1/3 cendinp parts of the curve represent -Oie recombination of the

triphenylmethyl radicals (formed in the first act of the
reaction) before reaching the equilibrium concentration. The
descending part of the curves represents the recombination
of the triphenylmethyl radicals
(2(C6H 03 C. '* g. (C6H03 C - C(C6if 03 ) in the first act of
the reaction. The experimental results prove the primary
formation of the above-mentioned radicals. The maximum of the
kinetic curves is not caused by an increaue in temperature of
the reaction mixture. The character of the kinetic curves
corresponds to an accumulation of the intermediate product
in the successivebimolecular reactions. The constants of velocity
and the activation energy of the reaction of radical formation
can be calculated from the kinetic curves found in this paper.
According to these results, elementary reactions of the type
RIX + YRII --o- R's + XY + ~ RII under suitable energy conditions
can proceed with the formation of free radicals of insig-
nificant energy. It has hitherto not been possible to generalize

A13STRACT: According to K, Ziegler et al. (Pef 1), the inverse reaction
of the recombination of triphenylmethyl radicals must proceed
with an activation energy which is equal to the difference
between the activation energy of the dissociation and the dis-
sociation heat of hexaphenylethane (6 - 8 kcal). By the
method of paramagnetic electron resonance, this conclusion
could be confirmed by immediate measuring of the dimerizationrate
of triphenylmethyl radieals in the solution. A capillary with
a clution of hexaphenylethane in toluene was heated to 100 0
and then it was rapidly cooled down to the temperature of
the experiment. This operation was carried out in a thermo-

the experiments is discussed in short. A fi,:Iure showo 2

at -64 and -550. The recombination rate incpeases noticeably
witi temperature. An equation for the kinetics of the radical
rec)-,ibination is given, the inverse reaction is taken into
acc)jnt. The second diagram demonstrates the tem,,.erature
dep-~ndence of the equilibrium constant and the third diagram
shove the temperature dependence of the constant of the di-
merization rate. The Arrheniua (Arrenius) del-endence is well
satisfied. Thl-is, the direct determination of the dimerization
rate of triphenylmethyl radicals confirmed not only the existence
of an activation ener.-Y of this reaction but also its value
(which coincides with the difference between the activation
energy of the dissociation an~] the energy necessary for the
brelaking of the C-C bond of hexaphenylethane . The authors
