Found that while contact with an inert surface Jrhf-

decompn. The absence of chlorine in the end products
and the presence of RC1 indicates that the decompn
consists of the removal of HM, leaving an alefin.

The destructive alkylation of pehtane." at high temps and pressures without the use of
catalysts was carried out in a rotating autoclave. The optimum temp for converting ~,entane
into liquid, high-boiling hydrocarbons lies between 450-4600; the pressure for this temper
is 250-310 atm. The optiintim time for the reaction is 2 hro. Prolongation of time, as
well as increase in temp, leads to formation of ga6eous products. The `-.ydrocarlons formed
during the thermal conversion of pentane are a result of destructive alkylation,
cyclization, and crackIng of pentane with subsequent polymerization of the unsatd hydr-
carbons.

The effect of the ratio of hydrocarbon to C1 on
the yield of raonochlorbutanes was found to be
considerably less than in the case of the chlorl
nation of n-butane. It was also found that
raising the vol velocity resulted in an increase

in the yield of =nochlorbutanes. The activa-
tion energy of the chlorination of isobutane
is 20,000 cal/mole, which is close to that of

AB"'ITRACTi Polypropylene - a stereoregular polyolefin - occupies one of
the first plices among modern synthetic materials. This is
due to its easily accessible raw material and to its aeveral
eminent properties. Polypropylene is capable of forming
fibres equal to the beat synthetic fibres. Objects made from
polypropylene, unless subjected to mechanical influence, pre-
serve their forms in as high aa 1500 C. They can be used for
numerous technical purposes as for manufacturing electric and
radiotechnical appliances, transparent films, etc.

In the following molybdenum oxides and mixtures of molybrl,~njui oxid,;
,aith copper-, zinc.., nickel-, and cobalt- oxides are mentioned as
catalyzers and shortly discussed.
The effect produced by catalyzars can be improved by the addition
of metal hydrides. For this purpose the hydride:3 of alkalis and alka-
line earths lithium, ,alkanatell and the boron hydrides of lithi-M;,
sodium, magnesium and alum1num. In connection with borcn fluoride
also metal fluorides can catalyze the polyrerization reactioo of the
olefins.
Nothing exact is hitherto known concerning the mechanism of oxide
catalyzis; a comparison between the efficacy of the various ox.,Ieg
shavred that the oxides of the V - VIII -glib-Croup are particularly
suited for this purpose. The catalyzer effect can be con3iderably
reduced by the treatment with hydrogen at 5oo0G. Tile iduao expresged

ABSTRVCT4 The chemistry of polymeric compounds has recently been enriched"by
new methods of polymerization which make it possible to obtain
a tereoregaar crystalline poly- t( -olef ines.
The papers hitherto published contain hardly any data concerning
the conditions of the synthesis of the polymerization proiuots.
Experiments hitherto carried out show that in the oaze of polymeri-
zation under atmospheric pressure as well as at increased pressure
the beat results were obtained (at a temperature of nearly 500).
As may be seen from table 1, practically the same results were ob-
tained by working with pure and technioal propyles. The X-ray
picture of propylen disclosed the existence of sharp ollara et aria ti' o

TITLEs Extensive Chlorination of Propane on a Moving Contact (Glubokoye
khlorirovaniye propana na dvizhushchemsyakontakte)
PERIODICAL: Doklady AN SSSR, 1957, Vol. 116, Nr 5, PP. 800 - 803 (US7,7)
ABSTRACT: In recent times there is a more and more increasing for
the products of a thorough chlorination of hydrocarbo,~o, especial-
ly of alkanea. Beside merely theoretical interest the poljchlc,.--
substitutes are used as semiproducts for the production of poi-
sonous chemicals, artificial fibres, ard others. It is known that
a considerable heat liberation complicates the process of the re-
action of alkane chlorination . This leads in a series if cases to
a practical impossiblility of the synthesis of the wanted chloride
under industrial conditions. On the other hand, there is the pami-
bility to carry out the chlorination on a movint; chemically inert
heat carrier as it is known from the petroleum working up. Due to
a direct contact between the reagents and the heat carrier the
reaction heat is comparatively easily conducted, ihe temperature
regime of the process is conserved here. For this purpose a rnodel
device with a moving heat carrier ("mullite") was used. (f-!;-,are 1).
Card 112 It runs in a closed cycle and iu regenerated by the combust.1un of

the carbon deposited on it. The experimentu on the model device
have shown that the yield of dichloride does not exceed 25 - 30
With the increase of the relations chlorines propane increases the
degree of the pyrolysis. The characteriatic of the rroducts frac-
tioned on a rectiting column is Given in table 2. 1,1-, 1,2-, 1,3-
and 2,2-dichlorpropane, 1,1,2- and 1,2,3-trichlc_,,- jpane, 1,1,1,2-
and 1 9 1 2,2-tetruchlorpropane were isolated anJ .heir phy:3ical-che-
mical indices were determined. lli~;her chlorlaes were not investi-
gated. The results of the mentioned experiments on a moving heat
carrier layer have shown that this proceso can be important
for a thorough propane chlorination. Furthermore the reaction pro-
ducts can be used for the destructive chlorination for the pro-
duction of tetrachlorcarbon and tetrachlorethylene. The moving
heat carrier and a Gradual introduction of chlorine are obviously
the decisive factors which guarantee a normal course of the reac-
tion in the case of a such thorough propane chlorination. There
are 3 figures, 2 tables, and 3 references, nona of which is Slavic.

ABSTRACT: Various chemical processing riethods of petroleum hydrocarbon
are described and the iml)rtance of the process of polymeri-
zation is emphasized. Recently, scientists developed a new
synthetic method of obtaining ethyl alcohol from ethylene.
Ethylene is distilled under a pressure of 70 atmosphere and
a temperature of 250Ctunder the influence of an acid catalyzer.
In 1957, the Sumgait plant produced dozens of tons of synthetic
ethyl alcohol. Besides alcohols, synthetic fatty acids obtain-
ed from petroleum are of great importance for the chemical
industry. Soviet engineers and scientists elaborated a new
method of oxidizing petroleum paraffin into fatty acids; this
process is carried out by using liquid paraffin hvdrocarbons.
With the help of chemical petroleum syntheses, one of the most
important taaks of Soviet national economy is being solved.
Foodstuffs which were formerly used for technical purposes
will be completely replaced by synthetic products. Soviet
Card 1/2 scientists were the first to find a new industrial method of

obtaining phenol and acetone simultaneously from isopropyl
benzene. Moreover, the chemical synthesis of petroleum
represents a valuable source for organic dyestuffs. An exten-
sive research program is being carried out in Soviet research
laboratories to obtain new materials of stereo-rebular struct-
ures with even more valuable combination properties than poly-
propylene and polyethylene.
There are three sketches and one illustration.

ABSTRACT: Tsigler in his works maintained, that Jin heating ethereal
solutions of lithium-aluminumhjdride with ethylene (at a
temperature of 180-2000C) a mixture of a-olefines is formed
under pressure: butene, hexene, decene and dodecene.
Corresponding to experimental data it is to be expected
that the actual catalyst in this case is tetraethyl-lithium-

ABSTRACT: Of late in Publications several references were made
in publications in regard to the mechanism of the
stereospecific polymerization of the a-olefins. In
regard to these references the authors of this letter
wish to report some experimental data gathered in in-
vestigations on the poiymerization reaction of propylt_,rle
in the presence of the catalytic system TiCl 4 and Al(i-CAH 9)3'
Studies on the change in molecular weight of the poly-
propylene formed in the reaction show that already 15
seconds after the reaction begins a product of hi-h
molecular weight has formed. The duration of the reaction
does not change the molecular weight of the pol-' -m(.,r fozled.
The structural-chain keeps adding polym.~ric units in a

of the catalytic motallo-organic complex in the propylene,

ABSTRACT: These reactions are equiponderant for unsaturated hydrocarbons.
The thermodynamic calculation of the reAction mentioned in the
title above is interesting. It is also of essential practical
importance for the choice, of the optimum parameters of the prom
cess. The authors give a short bibliography (references 1-3).
At present the possibilities of a rigorous thermodynamic compu-
tation of the reaction mentioned in the title are given, that
is by using the molecular and spectroscopic data for tertiary-
butylchloride. Its molecule has a symmetry of the class C 3v*
It can be regarded as a C-Cl frame to which 3 symmetric XH3

"shaded" model of the molecule was chosen that is, a C4i coma
bination of each methyl group was regarded as being in the same
plane as the C-C combination. With chosen angles and distances
between the atoms (both given here) the atom coordinates show
results which are given in table I. The "VI axis coincides with
the direction of the C-C combination. From that the moments of
inertia of the whQle molecule are computed. Their product I XYZ

the last-mentioned product render it possible to compute the
corresponding terms of the entropy of the free energy and of
other thermodynamic functions of one mole of the respective gas
in dependence on the temperature. For the entropy and for the
free energy formulae, (1) and (2) are derived. From these the
vanes of the thermodynamic functions were computed which are
caused by all progressive rotary motions (those of the CH gyros=
copes included) and by the oscillating motions of the moy2culas
(table 2). These functions were computed with a potential of 2ooo
KaI per Mole which accords best with the experimental data (refe-
rence 1) with regard to the corrections because of the retardation

tained. Low-molecular (liquid) reaction products could not be
detected. On the polymerization of ethylene without pressure
but in the presence of a solvent no polymer was formed. The

of the solvent (according to data of publications) the admis-
sible quantity of oxygen is considerably smaller. Under iden-
tical conditions also polypropylene was obtained. It could be
found that on polymerization under pressure and in the presence
of a solvent the activity of the chromium-oxide catalyst is
connected with the presence of chromium-oxides of the valences

ABSTRACT: In the present letter to the editor the authors write: As is
known, heterocyclic compounds which are usually among the
aromatic ayetems exhibit the properties of dienes up to a cer-
tain extent. This becomes especially manifest in compounds of
the furan series which are able to combine with maleic acid
anhydride. Less distinct becomes this fact in the case of thio-
phene. In this connection the possibility of a polymerization
of such compounds in the presence of a complex organometallic
catalyst which contained trialkyl aluminum and titanium tetra-
chloride was investigated. A number of experiments showed that
furan, a-methyl furan and thiophene in n-hexane form solid com-
pounds in the presence of the catalyst mentioned. These com-
pounds are practically insoluble in aliphatic and aromatic
hydrocarbons. The pr8duct obtained from furan remains unchanged

PERIODICAL: Izvestiya Akademii nauk SSSR. Otdeleniye khimicheskikh nauk,

ABSTRACT: By way of introduction the chromium oxide catalysts which are
successfully used for th(! polymerization, and which are mention-
ed in publications are enumerated. (Refs 1-4,5). The strong ca-
talytio effect exercised by these catalysts is based upon the
readiness of chromium to pass over from one valence stage into
an other. In the present investigation the composition, the
physico-chemical properties, and the dependence of the activi-
ty upon the production method of the catalysts, which were pro-
duced by impregnation of the aluminum silicate with CrO
and
3
chromium nitrate with successive activation at high tempera-
tures, was investigated. Chromium, which is otherwise reduced

silicate almost completely as Cr( VI). This was proved by in-
vestigating the thermogram of the catalysts (method accordir
to Balandin an4 Rode Ref 6), which exhibited an exothermal e.~ -
feet (Tables 2,3) which is caused by the interaction of CrO 3
and aluminum silicate, and by which the Cr VI on aluminum sili-
cate when heating to 3500 is preserved. The dependence of the
activity of the catalyst was investigated with an aluminum
silicate which was impregnated at first with CrO 3 and then with
chromium nitrate. Apart from the chemical analysis also the
weight, the specific Weight, and the porosity of the catalyst
was determined. Its activity was determined by the quantity of
the solid polymer formed. Furthermore, the influence of the
activation temperature on the composition of the catalyst was
studied. (Table 1). Here it was found that the lower the acti-
vatiori* temperature is (3000), the higher is the portion of Crl~
The catalyst, however, remains inactive because of the water
still combined with the aluminum silicate. The activation tem-
Card 2/4 perature had therefore to be chosen in such a way that the de-

hydration of the aluminum silicate took place while on the
other hand the Cr VI content in the catalyst remained almost
unreduced. This was possible in a vacuum at 3500- Furthermore,
a connection between the beginning of the active effect of the
chromium catalyst and the formation of intermediate chromium
oxides at 3500 was found. Finally, the influence exerted by
carrier substances on the activity of the chromium catalyst was
investigated, and experiments with aluminum silicate, silica
gel, aluminum oxide, and activated coal were carried out. Alu-
minum silicate and silica gel proved to be the beat carriers
for CrO 3* The action of chromium catalysts as polymerizers is
based upon their high sorption capability and the readiness of
being reduced under the influence of high temperatures and in
presence of hydrocarbons. The regeneration of the catalysts
was also investigated. There are 7 figures, 5 tables, and 6
references, 2 of which are Soviet.

ABSTRACT: Since recently the problems of stereospecific polymerization
of U -olefins with complex metallo-organic catalysts have
attracted the attention of many research workers. This can
be explained by the theoretical interest in polymerization
reactions which yield stereoregular polymers on the one hand,
and by valuable technical properties of the products formed,
on the other hand. The mechanism of stereospecific polymeriza-
tion of CK-olefins and the properties of the polymers were
frequently the subject of publications (Refe 1-8). Least
attention in the discussion wns paid to the synthesis of

basis (Refs 5-8). This is what induced thp authors to write
the present paper. In an experimental part they deal with the
production of the initial substance, course, duration, and
details of the reaction as well as with the quantity of the
catalyst used, The ready polymer is described with respect to
its properties. Figure 1 shows the dependence of the poly-
butylene yield upon the duration of reaction. Figure 2 gives
the radiograms of amorphous (a) and crystalline (b) poly-
butylene. From figure 3 the dependence of the characteristic
viscosity of polybutylene (A) can be seen and that of the
content of crystalline substances (B) on the molecular ratio
of the catalyst (C 2H )3 Al : TIC1 4j Figure 4 reveals the
dependence of the Me viscosity A) and the yield in poly-
butylene upon the reaction temperature. There are 4 figures
and 9 references, 3 of which are Soviet.

TITLE: Some Rules of Polymerization of Propylene With the TiCl 4 4- A1R3

ABSTRACT: Different opinions were expressed in publications on the rules
and mechanism of stereospecific polymerization of a-olofinea.
'Many problems in this respect have, however, remained unclear.
Therefore, some observations made by the authors in dealing
with the subject mentioned in the title are interesting.
(AIR3 = Al(Iso--C4H9)3 ). The experimental system had been de-
scribed before (Ref 5)- It can be assumed that an exchange re-
a2tion takes place between TiCl 4 and the metallic alkyl forming
organotitanium compounds (Ref 6). The latter decompose due to
their instability, and form free radicals. The polymerization
of styrene, for instance (Ref 7), can be initiated in this way.

liG alkyl is, so to speak, a "supplier" of the alkyl radical.
The propylene polymerization is a chain reaction. Already
17 seconds after its start, a polymer with a high molecular
weight is formed (Fig 1) which remains unchanged for a long
time (up to 1.5 hours). Thus, the molecule attains a maximum
size, and does not grow any morn. The catalytic activity of the
complex catalysts of the Teiglnr type decreases with time
(Fig 2). This is possibly,due to the fact that the amount of
.resulting organotitanium compounds is reduced with an increas.
ing alkylation of titanium chlorides. Accordingly, the ab-
sorption rate of propylene also decreases. If, however, TiCl 4
is first poured into the reactor, and thc~n aluminum alkyl
evenly added at a low rate, n.g. within 3 hours, the activity
of the catalyst is maintained for a long time, and the polymer
yield is considerably increased. An explanation of these phero-
mena is attempted with reference to the assumption made by
C. D. Nenitzesou (Ref 4). The polymerization process initiated
by Tsigler catalysts is highly sensitive to admixtures of va-
Card 2/3 rious types in the monomer, particularly to oxygen (Fig 3).
