i four polymers have almost the same structural elements, with bands at 1000-1100 cm
corresponding to Si-O-Si-and at 1400-1500 cm- correspond ,115. 7110 '.A
Lng to Si-Cr
,mechanical properties of the polymers wore not affected by the solvent. All four polyphenyl
siloxanes had a very high glass temperature (Tc=300C). The close To values for the poly-
phenylsiloxanes show that the conditions of preparation do not significantly affect the struc-
ture. The reaction conditions also do not significantly affect the polydispersity of polyphonyl-
silexanes. - The degree of polymolecularity and the average molecular weight of the poly-
phenylsilexanes increased, depending on the solvent used, in the order benzeno-tobleno-
',xylene-dinil. A mechanism for the formation of these polyphonyloiloxanes is proposed.

ABSTRACT: Viscosimetric andoptical studies on polyphenylalloxanes In dilute and very
dilute solutions of benzene, tolueno, xylene and dinil showed that the solvent affects only
the molecular weight of the polymer. At a molecular weight ranging from 10, 000 to 50, (10
0-7 ML%
the viscosity of the polymer in solution Is described by the equation flq/ = 1. 305 x 1
indicating thatthis polymer consists of short, rod-shaped molecules. From 50, 000 to 2,700, 00
the Mark-HouwInk equation assumes the form pV = 1. 93 x 10 4MO. 634, 1. e., the moleculps of
the ~olyrner are so long that they assume the form of a coil. For all fractions of polyphenyl-
siloxane, the molecular weight was measured in benzene by light diffusion at an angle of 90
1/2

i': and the specific viscosity was measured in benzene at 20C. For the first fraction, the
asymmetry of light scattering was measured and the true molecular weight was calculated.
The characteristic values for the difference between the refractive Index of the polymer and
the refractive index of the solvent form a straight line, Indicating clearly that, accdrding
to the theory, they all have the same cyclolinear structure proposed by Brown it al.
(J. Amer. Chem. Soc., 82, 6194, 1960). The flexibility of polyphenylsiloxane molecules
was also determined and the pertinent tabulated data show that the rigidity of the polyphenyl-
siloxane molecule. Is higher than that of the molecules of polydimethylsiloxane and
polyisobutylene. The study of polyphenylsiloxane in very dilute solutions showed that po-i
lymers with a relatively low molecular weight (40, 000) have an abnormal slope of the
ev sp./o-c curve in benzene. Orig. art. has: 5 figures, 1 table, 2 formulas and I
chemical structure.

TITLF- The Investigation of the Liquid-Phase Hydration of Acetylenel
According to Kucherov. I. The Effect of the Composition of the
Catalytic Solution on the Course of the Reaction
PERIODICAL: Tr. In-ta khim. nauk. AS KazSSR, 1958, Nr 2, PP 158 - 172
ABSTRACT: The hydration of C2H2 was studied by passing it through a sulfuric~(
acid solution of HgO and Fe2(304)3 , depending on the composition
and the temperature of the solution, the rate and the duration of
passing C2H2 through the solution. The loss of catalytic activity
of mercury compounds in the course of the process is caused by re-
ducing them to mercury metal with its removal from the solution.
In the absence of oxide iron the deactivation of the catalyst takes
place more quickly, the introduction of Fe2(SO4)3, though pro-
moting the removal of mercury from a solution In a more dispereed
Card 1/2 state, Inhibits its reduction, increasing the reaction rate. The

Course of the Reaction
optimum passing rate of C2H~5 at 960C is 4.3 ml/min per 1 ml of contact solutionp
the optimum temperature is OC. The presence of H2304 is necessary even in
the presence of an intermediate compound formed between C 2H2 and the catalyst.
In the case of a change in the concentration of the contact solution, the yield
of acetaldehyde passes through a maximum corresponding at 960C to a composition
of 23.8% H2304 and 10% Fe (304) - the highest productivity is attained at 750C
and a composition of 13.~j H230~'and 17% Fe2(SO4)3. The introduction of small
quantities of chlorine reduces the total yield of CH3CHO leading to a rupture,
the addition of small quantities of CC14, C2C16, C H4Cl2 increases the yield of
CH CHO; chloroorganic compoundsp as well as NaCl aken in large quantities
Qrt a negative effect. In the beginning of the reaction the CH3CHO yield is
less than average, the maximum yield, exceedlng 100%, is attained after 3
hours, which is due to the initial formation and the subsequent decomposition
of intermediate products; later on the yield decreases again due to the in-
tensification of side processes.

that charging curves for alloys contg less than
34$ Pt are composed of a section which depends on

the nature of the electrolyte and a section which
does not. Curves of the charging of alloys contg
more than 34% of Pt depend on the nature of the
electrolyte throughout their entire extent. The
effect of electrolytes on the charging curves of
the Ist type permittea differentiation between R2
adsorption and H2 soln, calcn of the soly of R2 in
Pt-Pd allcqs with a precision of 10-15%, and plot-
tivf izotherms of soln of H2 in these alloys at
P atm. Found that increase of the Pt content
in alloys up to 34% brings about sharp lowering
of the s0!7 Of R2 and a homogenous mechanism ~;f
soln. Witm alloys contg more than 34% Pt, H2 is
only adsorbed under the conditions studied. in-
vestigated special properties of alloys contg less

Title Adsorption phenomena on Hg and alcohol-water solutions of electrolytes
Periodical Zhur. fiz. khim. 28/1, 137-101, Jan 1954
Abstract Two series of electro-capillary curves representing ethyl alcohol - water -
NaCl sat and ethylalcohol. - water NVRsat~ systems were measured and
it bWm~ evident that the boundary tension ol the aqueous salt solution
decreases in the zone of electro-capillary maximum as result of introduction
of alcohol Into the solutions Addition of water to the alcohol salt
solution leads to reduction of boundary tension on both ends of the electro-
capillary curve. It was established that the negative. adsorption of
alcohol corresponds to the po3itive adsorptiorL of water, The calculated
adsorption isotherms on the boundary with air showed that both salts in-
creased the alcohol adsorption and displace the adsorption maximum toward
less concentrated alcohol solutions. Ten references 5-USSR; 4-USA

ABSTRACT: This is a lecture held at the conference on the use of the
methods of marked atoras in chemical industry, which took
place from March I - 3, 1955. Data on the hydrogen content
in skeleton nickel catalysts obtained according to various
methods (References 1, 2 and 3) are given. It is shown that
even with similar conditions of production of the catalyst
samples the q H values (hydrogen volume per gram of catalyst)
Card 1/3 hardly agree 2 at all. In order to find the reasons for this

divergence those procosoaB which occur on the surface of the
dehydrogenated catalyst in the presence of other aubstancee,
which could lead to the formation of additional hydrogen
quantities (or on the other hand to the interruption of hydro-
gen separation) were investigated. It was found that in the
case of an anode polarization by small amperages the skele-
ton nickel catalyst in the vicinity of the reversible hydro-
gen potential reacts like an electrochemically active nickel
electrode. The method of charge curves was used for thedeter-
mination of the nature of processes observed in the dehydro-
genation of the skeleton nickel catalyst in aqueous alkaline
medium. It is shown that in the case of dehydrogenation from
the skeleton nickel by means of easily hydratable compounds
processes occur on the surface of the catalyst the nature
of which is about the same as in the case of the application
of a small anode polarization with nickal. In both cases be-
sides the dehydrogenation of the hydrogen enclosed in the ca-
talyst two processes compete with each other, that is to say,

ABSTRACT: The present paper investigates whether additional
separation of hydrogen takes place during vacuuc-dehydro-
genation in a steam atmosphere. In order to determine the
quantity of hydrogen sorbed by a gram of skeleton nickel,
the latter was produced with the use of a "heavy" 01(&U (Vith
a certain content of deuterium) by leaching out aluminum
from the aluminum-niokel alloy. The weighed portion of the
deuterium-containing catalyst was treated with an acid,and

this one has the disadvantage that hydrogen and deuterium
are chemically not identical and that thus the calculation

ABSTRACT: In previous papers (Refs 1-3) it was ascertained that in
binary alloys Pd - Pt~ Pd - Ni and Pd -- Ag the sum of dis-
solved hydrogen and metal in palladium In the two-phase range
until the disappearance of stagnation on the curves Q - V
(caused by the a--p conversion) always remains equal to the
quotient between the number of free spots in the c-band and
the total number of atoms of the alloy ox of the Pd, and
is about 0,53. The present paper investigntes the sorption
and heat of solution Of the hydrogen in dispersc Pd-Cu alloys
at room temperature (240C). The aorption was neasured accord-
ing to a method worked out by reference 8, and the working
process was already described (Ref 1). The Q - V curves were
measured at 24 0, and current densities from 5-1o-4 to
2.10-3 a/cm2. The curves obtained (Fie -1) show distinctly the
influence of Cu on the total solubility of 11 in the alloy.

TEXTt In continuation of the papers (RZhKhim, 1960, No. 2, 3760; No. 12,
46o84; No. 13, 51109) the authors investigated the solubility of hydrogen
(HS) in the ele.3trodeposited alloys Pd - Fe in the range of 0 - 32.6% of
Fe and Pd - Cc in the range of 0 - 51.2'% of Co at 20 0C. This was done by
the method of measuring the charge curve3 (CC). The CC sections
corresponding to HS and to the adsorption of hydrogen were subdivided by
experiments with the same electrode but different electrolytes (H 2 s04 an,!
HC1). The extent and the relative disposition of CC are indicative of the
monotonic reduction of HS and of the strength of the compound M - H with
decreasing Pd content of the alloy in the pressure range studied. The

influence of Fe and Cc on the character of sorption is almost the same.
The.amount of hydrogen, the disnolution of which corresponds to a complete
occi.apation of the d-band of Pd in the alloy by electrons, was calculatea
from the extent of the slopin& CC sections. The slope of the correspondir,
our-~es makes it possible to estimate the number of electrons promoted by
an atom of the introduced metal into the d-band (RZhKhim, 1955, 1903; 196(,

TEXTs With the aid of a previously described method (RZhKhim, 1960, No.
15, 60716; 60717) it was shown that, unlike what is the case with Pt, the
overvoltage of hydrogen formation on disperse Pd depends largely on the
pH value. For the Pd electrode, the transition of I n H 2so4 to 2 n NaOH
is accompanied by an increase of the absolute value of and by an increav~-:-~
of the coefficient b of Tafel's equation from 0.020 to M52 v.
Dissolution of Pt or Rh in Pd results in a rapid decrease of the value of

the second one appears at 0.400 - 0.450 v and 0.700 v, respectively -
In both forward and reverse direction, the anodic charge curves show a

TECT: The author puts forward a scheme of distribution of electrons and
Irvacancies" in 4d- and 58- bands in the Pd - Ag system and in 4d- and s- bands
in the Pd-Cu system. Using simulation notions and assuming a limited number of
vacancies for hydrogen dissolution in the Pd - Ag, Pd - Cu and Pd - Au systems,
isothermal equations of hydrogon dissolution Iii the alloys are obtained. They
serve to determine the magnitude of the chemical potential of hydrogen dis-
solved & /)- H, and the coefficientoG , characterizing the deviation from the
ideal state in the Langmuir equation. An equation Is obtained for calculating
