Interaotion of hydrogen silanes D244/D307
general reaction wast CII 2 'CH-CH 2- NH2 +R3SiH ---),R3Si-CH 2-CH 2- CH 2- NH26
The yields of the product were 60 - 70 % for trialkylsilanes and
30% for alkylaryl- and for the triaryl silanes. The reactions of
trimethyl- and triethyl- Bilanes with allyl alcohol, using plati-
nized carbon as the catalyst, gave R Si-O-CH 2-CH 2- CH2 with evo-
lution of H2' Tributyl- and tripheny?_ silanes gave in addition
R3~ i-CH 2-CH 2-CH 2-0H. The reactions of triphenyl-, triethyl- and
tributyl- silanes with unsaturated tertiary alcohols resulted in
the attachment of R~Si- groups to the multiple bonds, no formation
of others being obs rved. The combination of R 3SiH with diallyl-
oxydialkyl(phenyl)silane was carried out, using Pt catalysts. The
yield of the product, resulting from the combination with the double
bonds of both allyl groups, was found to be higher than that from
the combination with the compound containing a s.-Lri_,rle substituted
allyl group. The latter was not formed at all in the combination
with metliylphenyl-diallyloxysilane. The former products are liquids,
stable when heated in air at 4000C. Hydrolysis of the products in
10 % HCl gave organic silicon alcohols with the OR group in Y- position,

TEXT: Investigation was made of the reactions of
methyl-, ethyl-, propyl- and butyl bromides, bromobenzene, methylene
dichloride and dichloroethane with silicon, to discover whether
alkylbromosilanes can be prepared directly. The effect of catalyst
(Si-Cu), temperature, and contact time was studied in relation to
the composition and the yield of products. It was shown, for CH Br,
3
that the reaction with Si below 3201C proceeds with the formation
of a high froportion of trimethylbromosilane (18-20%), (and a small
amount of CH7,),,Si) but above 3600C its quantity decreases to -5%

and the proportion of ClViBr3 increases up to 20%. The effect of
temperature on the reaction between bromobenzene and Si is analogous,
but the reaction proceeded satisfactorily only between 4000 and 5000C.
The yield of the product was constant at 41o - 46oOc (46 - 49 %)
and decreased to 37 % at 4800G. For the reaction between ethyl bro-
mide and Si, the yields of triethylbromo- and diethy3dibromo- ailanes
are lowered and there is a sharp increase in the formation of ethyl-
tribromosilane (the most stable product at 310 - 3600C). Propyl and
butyl bromides give very little alkylbromo- silanes, the main reac-
tion products being tetra- and tribromosilane. It was found that the
use of activated Cu as catalyst activated all the rottotiona with Si.
In the case of alkyl bromides, the catalyst was most active 10-12 hrs
after the initiation of the reactions. For dihalogeno- derivatives
the activation took place in a shorter time. The most active catalyst
was formed by the action of alkyl halides on a finely powdered Si
and reduced Cu powder, the ratio of SitCu being 8Ot2O. The reaction
bOtwQOn CH2C12 and Si with Cu as catalyst proceeds in two directions:
1) with the full utilization of Ch2C12 M010OU101

the yield of 62-5% by hydrolysing methyldiethoxydisilylmethane.
Beginning with pentaethyloxydisilylmethane, the pentaalkyl- deri-
vatives of disily1methane are stable compounds which are not con-

X Cl or Br. As the chloromethylation of alkylbenzenes gives a
mixture of p- and o- chloromethylalkylbenzenes, the proportion
of the isomers in the reaction products was determined by their
oxidation with CrO3, whereby only para- isomers are oxidized.
The proportion of the para- isomers was found to be 70 %, 75 %
and 98 % for the chloromethylation of trimethylbenzyl-, triethyl-
benzyltripropylbenzy- silanes respectively. Also investigated was
the chloromethylation of toluene, ethylbenzene and igo- propylbenzene.

dimethylphenyl- and methyldiphenylallylsilanes, dimethyl- and
meth.ylphenyldiallylsilanes, methyl- and phenyltriallylsilanes
and tetraallylsilane. The monoallylsilanes gave only solid poly-
mers melting between 230 and 3000C in a maximum yield of 18%,
up to about 50% of them having an isotactic atructure. The di-
allylsilanes gave both liquid and solid polymers with maximum
total yields of 85 - 90%. The phenyltriallyl compound gave up
to 100% of polymers softening at 400 - 5000 , while methyltri-
allylailane gave only traces of solid polymer or very small amounts
of liquid polymer. Tetraallylsilane gave up to 15 % of insoluble
solid polymer decomposing above 3500.. The copolymerization of

a rule, in any one class of alkylarylsilanes those in which the
alkyl group is ethyl have the highest refractive index. The re-
fractive indices of dialkyldiarylailanes are about 0.05 units
higher than those of the aryltrialkylailanes with the same alkyl
and aryl groups. In the case of the phenyltrialkylsilanes, the
introduction of a methyl group into the 4- position of the phenyl
ring and then a second methyl group into the 3- position increases
the refractive index, while the situation is reversed in the case
of the aryltrialkylsilanes. The specific dispersions of aryltri-
alkylsilanes are 15 - 20 %, lower than those of the corresponding
diaryldialkylsilanes. The refractive indices of the hexaalkyl
derivatives of disilylmethane, disilylethane, and disiloxane
increase with a rise in the molecular weight, those of the di-
ailoxanes beind less than those of the corresponding members of
the other classes. On passing from hexamethyldisilylmothane to
the corresponding ethane and propane derivatives, the refractive
index increases by 0.0025 units per CH2 group added, while the

dispersion of the hexaalkyldisiloxanes is anomalous, the ethyl
compound having the lowest value. The refractive indices of
polyethylsiloxanes increase by 0.007 per diethylsiloxy group
and are much higher than those of the corresponding polymethyl
compounds. Dialkylsilanes have much higher refractive indices
and specific dispersions than the corresponding hydrocarbons.
The molecular refractions of all the compounds investigated
were calculated by Sauer's method (J.J~meir.Chem.Soc., 6a, 691
(1946) ) from established group and bond values and the results
were found to be in good agreement with those calculated from
the experimental data. There are-3 tables.

TEXT: The dielectric consthnts of 16 organosilicon
compounds of the following types have been investigated: hexa-
alkyl derivatives of disilylmethane, disilylethane, and disilox-
ane, and polyethylsiloxanes, most of them for the first time.
The dielectric constants were measured at 250 in n-hexane at
a frequency of 7-95 x 105 cps by the method of beats, with an
accuracy of 0.02 %. The apparatus was calibrated with benzene

Dielectric constants Vf24/D307
and checked on toluene and n-hexane. The value of the dielectric
constants given in the literature for a few of the compounds
(measured in other solvents) agreed well with those obtained in
the present work. In the hexaalkyldisilylmethanes and -athanoo,
the dielectric constant increases with the molecular weight,
while in the hexaalkylsiloxanes the ethyl compound has the highest
constant. From the figures for the dielectric constant, the den-
sity, and the refractive index in dilute n-hexane solution, the
dipole moments of all the above compounds were calculated by Hede-
strand's method (Z.phys. Chem., 2, 429 (1929) ). All the hexa-
alkyl derivatives of disily1methane and disilylethane have practi-
cally the same dipole moment of about 0.57 D. In the case of the
hexaalkyldisiloxanes, the methyl compound has the highest dipole
moment of those investigated. The dipole moments of the polyethyl-
siloxanes increase regularly as the moleoular weight inoreasest
in aooordance with the relation
~A- 0.63 /n' _+1
where n+1 is the number of oxygen atoms in the moleculo of the
polyethylsiloxane. There are 5 tables.

TEXT: The solidification behavior of 31,organosilicon

melting points and purity, and the conditions under which glasses
are formed. The compounds were of the following typest hexaalkyl
derivatives of disilylmethane, -ethane, and -propane, and of
disiloxane, phenyl-, 4-methylphenyl-, and 3, 4-dimethylphenyl-
trialkylsilanes, diphenyl-, bis-4-methylphenyl-, and bis-3,4-

dialkylsilanes, and an aryldialkylsilane. The main feature of the
apparatus used is that the sample was contained in a double-walled
glass vessel immersed in liquid nitrogen, the rate of cooling being
controlled by the degree of evacuation of the space between the walls.
klany of the compounds underwent pronounced supercooling and others
did not crystallize but formed glasses. Where a. glass was not formed,
the m.p. of the material as such and the true m.p. of its main con-
stituentwere determined graphically b Rossini's method (J. Res.
Nat. Bureau Standards, 32, 197 (1944) . In the series of phenyl-
trialkylsilanesq the methyl and propyl compounds supercool only
slightly and then crystallize spontaneously, while the ethyl com-
pound crystallizes only after the deeply supercooled liquid is
seeded, and the butyl compound forms a glass. Somewhat similar
behavior is found with other series of compounds, the following
also forming glasses on cooling! 3,4-dimethylphenyltripropyl- and
-tributylsilanes, diphenyldiethyl- and'-dibutylailanes, bis-4-
methylphenyldimethyl- and -dipropylailanes, bia-3,4-dimethyldiethyl-

ABSTRAM This is the third article in a series on synergism in
polysiloxane-hydrocarbon lubricant mixtures. Previous studies
showed that the antivear and antifriction properties of polysiloxane-
hydrocarbon lubricants depend on the nature of the hydrocarbon. In
the present article, experimental data are presented on the effect
of, the nature of polysLloxanes on the synergism in polysiloxane-.

polymethylsiloxane (I), polyethylailoxane (11), and polymethyl-
phenylsiloxane liquids with.an average content of phenyl grou~g-,
called polymer 1 (111), and with a high content of phenyl groups,
called polymer 2 (IV). The results (expressed in graphs and diagrams)
showed that the synergetic action of polysiloxanes In the lubricating
mixtures is greatly dependent on the nature of the polysiloxane.
Effectiveness of the latter as hydrocarbon lubricating oil additives
decreased in the order 1I>1>I1DIV. This decrease is attributed to
the incr*asing thermo-oxidative stability in the polysiloxane
series*on substitution of the side ethyl groups in the polysiloxane
chain for methyl and phenyl groups. The synergism was observed not
only in the mutually soluble mixtures of polysiloxanes and hydro-r
carbons, but also in polysiloxane-hydrocarbon emulsions* Orig...

ABSTRACT: The effect of the oxidative activity of the ambient gas I
phase and the agents which intensify the oxidation on the antiwear
and antifriction properties of polysiloxane fluids under heavy loads
was studied at the Institute of Petrochemical Synthesis imeni As V,
Topchiyev, AS USSR. A polymethylailoxgne, a polyethylsiloxane, and

respectively, were used; in some experiments 4,41-diisopropyldiphenyl-
methane was added to the polysiloxane fluids to determine the effect
of the presence of an easily oxidizable hydrocarbon. The experi-
ments wdre conducted on a four-ball machine. Variations in the
oxidative activity of the ambient gas phase were achieved by conduc-
ting the experiments in vacuum, in the air, and by blowing oxygen
at the rate of 12 1/hr through the lubricant in the four-ball chamber:I
In some experiments, varying amounts (0.5-3%) of isopropylbenzene f
hydroperoxide were added to the lubricating fluids as the oxidation
initiator. The dependence of the wear on the load, friction-vs.-
time diagrams, and dependence of the friction coefficients on the
load were obtained for temperatures of 50, 120, and 200C. It was
found that the oxidizing agents and easily oxidizable hydrocarbons
exert the same effect in polysiloxane fluids as in hydrocarbon
lubricants, namely, a decrease in seizing, which becomes degenerated
and is terminated. This effect on the lubricating properties of
1polysiloxanes increases with the decrease of the thermnxidative
Istability of the latter, e,tg,, in the sequence3
polysthylsiloxane - Polymer 1 -l- Polymer 2.
