ABSTRACT It was recently found that isopropenyloyclopropane at room
temperature
in the presence of palladium black absorbs 2 hydrogen molecules and
forms 2-methylpentane. The reaction takes place with an Intermediate
formation of 2-methylpentane-1 &-A -2. A scheme is given.
Isopropylcyc_
lopropane does not form at all under theses conditions. This peculiar
behavior of isopropenyl cyclopropane gives rise to the supposition
that the double bond existing in the side-chain weakens the stability
of the C-C bonds of the three.-member ring which lie near the substi-
tuent against their reactions of splitting and addition to hydrogen.
This apparently takes place thanks to a peculiar conjugation between
the cyclopropane ring and the double bond. The hydration of the
mention-
ed substance in the presence of platinum black takes place in a
diffe-
rent manner: 1,3 mol. of hydrogen are absorbed and a mixture of 70
0/0
isopropylcyclopropane and 30 '0/0 2-methylpentane develops. Tn this
czze.,
therefore, the splitting 9f the three-member cycle under addition ot
Card V4 hydrogen according to the palladium scheme takes place

the addition of hydrogen to the double bond with retention of the
propane ring, In the first reaction 0,6 mol-, for the second one 0*7
mol. of hydrogen are consumed. The present work studied the
additic..~n
of hydrogen$in the presence of the blacks of both metals, to two
other
hydrocarbons of the cyclopropane aeries which contain a double bond
in
the side chain (see title). With palladium black (at +20C)
vinY!cYclo-
propane readily absorbs 2 hy&ogen molecules and forms n-pentane. That
means that here the three-member ring, under addition of hydrogen, is
split just as easily as in the case of isopyopenyl cyclopropane, the
double bond of the side.chain being hydrated in this connection. If
the hydration is interrupted and only 1 H-molOcule is permitted to

of

the side chain; the rest is used for the addition to the isomeric
by-

black, had shifted into a conjugate position with the cyclopropane
rings 1-methyl-isoheianyloyclopropahe, produced due to
isomerization,,
with a conjugate position of the double bond in relation to the
cyclo.
propane ring apparently should behave analogously to
vinyloyclopropane
and isopropenyloydopropans in.the presence of palladium and
hydrogen.
Namely it should absorb 2 hydrogen molecules and be converted to
2,6-
-dimethyloctanee In the presence of platinum black the double bond
doeo
not shift. Therefore the hydration result is only
1-methyl-l-isohexyl-
cyclopropanso At 1600C this latter is converted to
2.,2,6-trimethylbap-
tane in the gas phase and in the presence of platinum-plated
charcoal
under addition of hydrogen* Thorefore the hydrogenolysis of the

the
dealkylation actually proceeds according to an ionic mechanism, a
connection is to be assumed to exist between the above-mentioned
chano

nucleus, as a whole, and with the electronic rediatribution

to the nature and the orientation of the second substituent. The
au,
thors considered it timely to carry out a more systematic

tion of several alkylaromatic hydrocarbons, together with

assistants that palladium charcoal cannot catalyze the hydrogano-
lysis of the cyclopentano (reference 6) and its homo*~o,-lico
(re-
ference 7). The data for alkyloyclobutanes lack. G',clopropane
was
more able to bind hydrogen to palladium on pumice at hiaher tem-
peratures than to platinum. The results dtained in present paper
(and in the title) are easily to be compared to those on
platinized
coal. The experiments have shown that ethyloyclobutane can be hy-
drogenolyzed on palladium charcoal at a somewhat higher
temperature
than on platinized charoo9l. Here also the two possible bindings
of the 4-part cycle were cracked, however, a branched isomer was
produced in a somewhat greater quantity (60%). Considerable dif-
ferences ftm the platinized charcoal were found in the case og
1,1,2-trimethylo3olopropane. It was proved that at 100 and 120
both
possible reactions of hydration took place: hydrogenolysis as
well
as isomerization with a subsequent hydration. Thus the catalyzate
contained gll 3 possible products of the fission of the 3-part
cyc-
le. At 220 the secondary reaction took placc to a greater extent,
and the mixture of 20-dimethylbutane and 2-mothylpentane amounted

ABSTRACT#
From works (references 1, 2, 3) recently published

it became known that the paraffinic hydrocarbons may
be cyclized

in Iresence of platinum during the formation of a
5-membered ring.

The direct possibility of formation of
cyclopentanee fxom paraf-

fins was reliably proved. For the purpose
of comparison the auth-

ors intended to investigate another
hydrocarbon, which was not

so much branched out as isooctane, and
the cyclization product of

which, however, should have a boiling
point auffidently distant

from the initial hydrooarton. By means of
that the individual iso-

lation of the oyalization product should
be rendered possible. For

that purpose 3-othylpentane was chosen,

ABSTRAM Dealing with the investigation of the hydrogenolysis of
alkyl-
cyclopropanes in the presence of platinum- and palladium-cata-
lysts it was of interest for the authors to investigate the iso-
merizing action of the catalysts upon the three-memberes carbon
cycle. The object of investigation in this case was 1,1,2-di-
nethylcyclopropane. The above-mentioned palladium- and platinum-
-chazcoal served as catalysts. The investigation performed in
thin manner showed that palladium-plated and zionpalladium-plat-
ed charcoal at a temperature above 2000 C causes a marked i2o-
merization of 1,1,2-dimethylcyclopropane to olefins. This iso-
merization occurs more actively on a rise of temperature to
Card 112 2500 C and its depth remains constant on a further rise
of

temperature to 2800 C. An analysis of the product of catalysis
showed that the isomerization in the presence of both catalysts
approximately occurs with a 60% yield. On that occasion the
lin1kage between the carbon atoms of the cycle which were hydro-
genized least and those which were hydrogenized most strongly
breaks, which is in agreement with experience. But the authors
also could determine another direction of the occuiring tear at
the expense of the bond at the tertiary carbon atom. A scheme
on the reaction of the isomerization, is given on page 301.

ABSTRACT% In the catalytic dehydrogenation of isopentane a mixture
of
5 components forms - the initial product, 3 isopentenes and
isoprene. The quantitative relation of the components depends
on the reaction conditions. In the present paper the relia-
bility of the three bromimetric methods - aocording to
Rosenmund (Reference 3), Gallpern (Reference 5) and Vyrabiants
(Reference 6) is examined. This control was investigated in
pure C -hydrocarbons and also in various artificial. mixtures
of iso~entane with isopentenes and isoprene shich differed in
the number of components and also in their concentration. It
Card 1/5 became evident that the method according to Vyrabiants is
not

75-1-23/26
BromOmetric Methods of Determining Unsaturated Hydrocarbons
in Isopentane-
Isoprene-Iaoamylone Mixtures
suitable for an analysis of such mixtures, because the error
assumes different values and attains up to 7 - 8 ~~10
(absolute).
The results obtained according to Rosenmund and Gallpern conv
firm the fact that the accuracy of the determination of double
bonds depends on the structure of the hydrocarbons and on the
-composition of the mixture; 2-methyl-butene(2) and 3-methyl-
butene(l) without difficulty absorb 1 bromine molecule on
bromination. 2-methyl-butene(l) and isoprene consume more
than 1 bromine molecule and therefore yield too high results,
relative to a double bond, in the determination according to
Roserunund and Gallpern. The analysis of mixtures with 3 or 4
components, but without isoprene, showed an average absolute
error of the determination of the olefines of + I %. On addi-
tion of iso.Drene to the mixtures with 3 components the ab-
solute error increases to + 3 %. The analysis of mixtures with
5 components showed that t7he absolute error in the case of an
isoprene content up to 20 % in the method according to Rosen-
mund on the average amounts to + 3 ~~ and according to the
Card 2/5 method by Gallpern -2 As the average error in the

75-1-23/26
Bromometrio Methods of Determining Unsaturated Hydrocarbons
in Iso-
pentane-Isoprene-Icoamylene Mixtures
determination of the total number of double bonds in
mixtures of 5 components according to both methods has a
systematic nature, it can be taken into account by the
intro-
duction of a corresponding coefficient (in the case of an
isoprene content up to 20 %). It was shown that the values
for the total number of double bonds which were once de-
termined according to Rosenmund and once according to
GalXpern practically ooincide after the introduction of a
correction coefficient. As the method of bromination only
makes possible a sum determination for alkenes and dienes,
the content of monoolefines can only be determined from the
difference between the total number of double bonds and the
content of dienes. In the present case an appropriate cor-
rection which takes into account the content of isoprene
must
therefore be applied to the bromimetric results for
determin-
ing the content of isopentenes. For the determination of
iso-
prene the photometric method according to Robey and Wiese
(Reference 17) was employed which is well applicable in the
Card 3/5 presence of monoolefines, but also of some dienes.
The average

75-1-23/26
Bromometric Method of Determining Unsaturated Hydrocarbons in
Isopentane-Isoprene-Isoamylone Mixtures
error of this determination is less than 1 51 (absolute).
Determination takes 1 1/2 hours, which time can be shortened
in series determinations to 20 minutes for one determination.
When the concentration of isoprene in isopentane-isoprene-
isopentene mixtures has been determined in this manner, the
content of isopentenes (P) can be calculated according to the
formula P - a.Pl-b. P is the found total number of double
bonds in the mixture, b is the concentration of isoprene in
the mixture and a is the correction coefficient. In the
method
according to Rosenmund a - 0,96 and in the method aecording
to Gallpern a - 1,04. All performed testa are exactly de-
scribed. During the elaboration of this method a short
article by Timofeyeva and collaborators (Reference 18) on the
same problem was published. In this article a correct-ion co-
efficient is introduced in the final formula of the calcul-
ation which only takes into account the error produced by the
Card 4/5 inexact bromination of iBoprene.

ABSTRACT:
This paper gives a chronological report on
the fundamental

publications on the investigation of the composition
of the

light fractions of the Soviet mineral oils which have hitherto

been made. In this connection special attention is payed to

those
publications which are edited by V. D. Zelinskiy, his

collaborators
and otudents (Refs 1-50). As may be seen from the

present paper the
current investigations of the mineral oil

fractions until the years
1937, 1939 were carried out mainly in

connection with a chemical
characterization of the light benzoin

and benzene ligroin fractions
of mineral oil. Only in the 1940's

methods were elaborated for the
intensification of the individual

investigation. of the light
fractions of the Soviet mineral oils.

sub-
groups). It was necessafy to investigate in detail the

are of the opinion that mere geological and geochemical
factors
are not sufficient for the production of experimentally
founded
theories on 'the formation and the change of petroleum under
the conditions of migration. A great number of important data
are necessary for the solu%ion of the problem of the
formation
of petroleump, namely the riature, the concentration and the
composition of the hydrocarbon components (or the non-hydro-
carbon components); i. e., of'the organosulfuric, nitrogen
and
oxygen compounds which belong to the composition of petrole-
um. , There are 160 references, 160 of which are Soviet.

ABSTRACT! Data on dialkyloyclohexanes of this kind are
rarely found in
publications (references 1 - 6). For this reason their ins
vestigation is interesting in spite of great experimental
diffin
culties.Certain surprising iActs are found: the
cis-isomer of
1,4,-di-isopropyleyelohexane boils at a lower temperature
than
the trans-isomer (reference 5) though according to the
rule of
Auvers, Skit the contrary would have been expected. The
reason
of this peculiar inversion of the boiling points remains
unex-
plained and still waits for investigation. In order to
find out
whether such-exceptions are found in the series of other
dial-

PERIODICAL: Doklady Akademii nauk 833R) 1958, Vol 122, Nr 6,

ABSTRACT: In recent years it was repeatedly noticed that the rule
mentioned in the title cannot be applied to 1,3-dialkyl
cyclopentanes and 1,3-dialkyl cyclohexanes. In these latter
series the interrelation of the properties of cis-and trans-
-isomers is reversed. By the example of the stereoisomeric
lt3-dimethyl cyclopentanes and 113-dimethyl cyclohexanes
tnis statement was confirmed by thermodynamic data as well
as by synthesis. Recently the authors have observed ouch a
case in which a peculiar deviation from the same rule took
place (Ref 1) in the 1,4-dialkyl cyclohexane series. In this
series the applicability of the rule under consideration was
Card 1/4 denied by nobody. It became evident that in the case of the
4

stereoisomeric 1,4-diisopropyl cyclohexanes the specific
weight and the refractive index are higher, thi molecular
refraction, however, and the malting temperaturi of the
isomer boiling at a lower temperature are lower; the
spectroscopic data have shown that the lattir isomer is a cis-
-form. So in this case not the trans- but the cis-form has a
lower boiling-point - contrary to the rule mentioned. The
observations so far collected make it possible to approach
the problem of the relations between the configuration and
the physical constants by a new methodl the applicability of
the rule mentioned is not only restricted by the arrangement
of the side chains in the dialkyl-cyclane molecule, but also
by the atomic number of carbon in the latter. The authors
believe that the deviation described above is a regular
phenomenon. The reflections mentioned make it possible to
conclude that stereoisomerie 1,4-dialkyl cyclohexanes with
12 or a few more carbon atoms in the molecule mustsimilar
to 1,4-diisopropyl cyclohexane, deviate from the rule under
Card 2/4 consideration. Thus the Auwers-Skita rule is only applicable

to the first members of the series of the 1,4-dialkyl

publications on boiling temperatures of the atereoisomeric

of the dependence between the differences in boiling
temperature
of the stereoisomers and the atomio number of carbon in the
molecule is not confined to the 1,4-dimethyl cyclohexane
series,
but applies also for the 1,2-dialkyl cyclopentanes (Table 2 and
line A of Fig 1). In the st ereoisomeric 1,2-dialkyl cyclanes
discussed here the boiling temperatures of the trans-form
increase more rapidly with increasing molecular weight than
in the cis-forms. In these cases, however, the Auwers-Skita
rule must have a somewhat wider range of applicability than
for 1,4-dialkyl cyclohexanes. There are I figure, 3 ables,

ABSTRACTs The authors have already previously reported ~ef
1) that in the
literature on the mentioned problem many opposing views are
presented. They concern the direction of cleavage of the
3-membered ring. Most of the authors assume that the linkage
between the two most hydrogenized carbon atoms (Refs 1-6) is
being cleaved under a hydrogen affiliation (I). But there are
also cases described of a ring cleavage in other directions
(II) (Refs 7-9). Ya. M. Slobodin and coworkers (Ref 9)
conclude
that an intermediate stage of isomerization of the alkyl
cyclopropane to an olefin is interpolated; the
olefinafterwards

of an incomplete hydrogenation was proved by the Raman
spectra.
Reference 9 does not present any definite causes of the
various
cleavage directions of the 3-membered cycle. There is,
however,
one important factor which is capable of affecting
thementioned
direction of cleavage, viz. the carrier of the hydrogenating
metal, in so far as the employed catalysts are mostly used on
carriers. As was previously proved by B. A. Kazanskiy
(Refs 10, 11)p silica gel and activated charcoal are able to
catalyze the isomerization of cyclopropaw hydrocarbons to
olefins. It was but natural to assume that the hydrogenating
metals, if they are applied on carriers which are able to
cause
isomerization resembling the two just mentioned cases, will
lead under suitable conditions to different cleavage direction
of the ring than this would be the case with inert carriers.
Actually, in the first case that olefin is hydrogenated which
is formed in the ioomerization of alkyl cyclopropane
(equation III); in the second case, the cyclopropane
hydrocarbon
itself will bo hydrogenated (equation I). The relative
isomerizing activity of such catalysts on carriers will thus
Card 2/4 determine the cleavage direction of the 3-membered
ring.

Effect of the Nature of the Carrier Exerted on the
SOV120-123-1-28156
Direction of Catalytic IlydrQgenation of Hydrocarbons of the
Cyclopropane
Series
In the present paper the authors describe tests concerning
the isomerization of cyclopropane hydrocarbons to olefins
in the presence of: aluminum silicate, kieselguhr and Pumice.
On aluminum silicates, ethyl cyclopropane was nearly
completely
isomerized to a mixture of olefine of normal structure
already
at 500; on kieselguhr, to 75 ~a at 1200, on pumice at 1200 no
isomerization occurredionly at 1700- 20 c,", were obtained,
then
at 2200 - 45 %. Thus, the influence of a carrier being active
as regards isomerization exerted upon the direction of the
hydrolysis of the 3-membered ring is unquestionable. There

ABSTRACT:
Hydrogen at the instant of its libtiration is capable of

of the diene. The attachment in
thii 1.2-'-and 34-Positions is

favored by the larger number of alkyl
groups in the lat and

4th terminal carbon atoms (di-isocrotyl and
2-mothyl-hexadiene-

2-4): the alky! groups at the 2nd and 3rd atoms of the

conjugate system have the same effect with regard to the

1.4--position
(isoprene ard di-Laopropenyl). By the reduction

with sodium solution in
liquid ammonia (Refs 1-4) or with
Card 1/3

simultaneously with the hydrogen attachment to the double
bond. It has recently become clear that the amides are
capable of catalysing the displacement of the double bonds
in mono-and diolefin hydrocarbons (Refs 7-10)- Consequentlyp
it could be expected that under certain conditions the
structure of mono-olefins resulting from the attachment of
a hydrogeii molecule to the dienes should depend, not only
on the structure of the initial. diene, but also on the
secondary reaction of the iaomerization under the influence
of the resulting metal amide. In order.to eliminate the
isomerizing effect of the metal amide, ethyl alcohol was
added tDthe sodium solution in liquid ammonia (Ref 11).
Besides, di-isopropenyl was reduced by calcium-hexa-.ammoniate,
and di-isocrotyl was reduced by sodium in liquid Ammonia (Ref
2).
The results are shown in table 1. From this it can be seen that
on the reduction from all its sources at the moment of its
liberation, hydrogen is attached almost exclusively in the
1-4-Position of di.-isopropenyl, The reduction of di-isocrotyl
is less selective, although hydrogen is attached here in the
Card 2/3 1.2-positions. From a comparison of the data for

ABSTRACT:
The purpose of the present paper is the
elaboration of a

quick and sufficiently simple method of the quantitative

analysis of isopentane-isoprozie-isoamylene mixtures. Such

mixtures are
formed on dehydrogenation of isopentane into

isoanylenes and isoprene.
Their analysis was complicated

and required much time (Refs 1-4). The
authors successfully

used a combination of two clLromatographic methods:
the

partition chromatography (Ref 5) and the "chromathermo6raphyll

(Ref 6).
The methods were worked out on pure individual

hydrocarbons and on their
artificial mixtures. The universal

"chromathermograph" was used for the
analysis (Ref 7). Alu-

deci-
phering of the initial curve is of considerable importance
in analyses of this type, Varimm methods are used for this
purpose (Refs 3,9). Thero are cases of an incomplete sepira-

tion for the solution of this quastion"Ref 11) is
sugi;ested.

ABSTRACT: In the present paper the dealkylation of 6
monoalkylbenzenes,
such as ethyl-, n-propyl-, isopropyl- n-butyl-, secondary
butyl-, and tertiary butylbenzene on an aluminosilicate cata-
lv--t was investigated. The investigation was performed
accord-
ing to the kinetic method and under conditions comparable
for all 6 hydrocarbons. The experiments were carried out in
the temperature range of 330--4900 (for ethylbenzene of
490-5500) and at different time of contact between the
reacting
substances and the cataryst,. It was found that the principal
Card 1/3 reaction in all experimentc was the separation of

principal reaction of dealkylation also side reactions take
place nuoh i-L!j re-dintribution of hydroien, polymorization,

merely the gaseous cracking products of monoalkyl benzenes.

tates the investigation of the cracking kinetics of monoalkyl-

(Refs 2,3), On the baoio of the data obtained at different
temperatures and volume rates apparent rate constants of de-
alkylation and , therefrom, the apparent energies of

were computed (Table 1), It was found that the depth and rate
of cracking is considerably influenced by the length and
structure of the side chain. This confirmp the ionic charac-
ter of the dealkylation of benzene homologues on silica-

ABSTRACT: It is known from publications (Refs 1-5) that during
cracking
of the eymenes the principal nnetion is the separation of
the isopropyl group, toluene and propylene being formed here-
in. It was found that the depth of dealkylation under other-
%vise equal conditions depends on the position of the methyl
group with respect to the inopropyl jroup. The influence of
the position of the second substituent in the lenzene nucleus
upon the depth of dealkylation of eymenes was determined only
qualitatively and by a few experiments. For this reason the
behavior of 3 isomeric eymenes during catalytic cracking on

investigated.

Kinetics of Dialkylbenzenes Dealkylation
In studying the contact-transformntions of o-, mvp and p-cy-
menes it was seen under given conditions that the principal
reaction was the separation of the isopropyl group, toluene
and propylene beinj formed. The absence of cumene and benzene
indicaten that the metbyl grnup in not separated during the
cracking of cymones. In addition to the principal renction
also
side reactions take place such as redistribution of hydrogen,
polymerization and isomerization, But as well as in the case
of monoalkylbenzeneB their significnnce is small and concerns
only tho separated isopropyl ginup. Toluene remains
practically
unchanged and may be regarded as an end product of the
cracking of eymenes. The kinetics of dealkylation is well
defined by the equation of Frost (Refs 8,9). On the basis of
the data obtained at different temperatures and time of con-
tact between the reacting substanceo and the catalyst the
apparent rate constants of dealkylation and, therefrom, the
apparent ener,gies of activation were computed (Table 1). For
comparison also the data regarding the dealkylation of iso-
Card 2/4 propylbenzene are given (also Fig 1). The different

ionic mechanism of the cra;-!:in.~, of hydrcarbons in the
presence
of aluminosilicate catalysts. The p-diisopropylbenzene was
fir:t
investigated during catalytic cracking. The experiments have
shown that them not only ten,.-,enf? Iiiit also cumene is
formed
(Table 2). As may be seen from the til '-1e the quantity of
cumene
at 4100 is considerably hi-(,her than that of benzone. At
temper-
ature increase of up to 4900 the quantity of unreacted
p-diiso-
prcpylbenzene as well as the quantity of cumene decreases and
the quantity of benzene increases. Apparently this reaction
proceeds accordin- to the type of the consecutive reactions,
the cumene beinj formed as an intermediate compound. It is
dealky"Lated to benzene i';hile it is still in the zone of re-
action. This reaction, however, requirea a more intense
investigation. There are 4 fioures, 8 tables, and 18 referen-
ces, 8 of which are Soviet.

ABSTRACT:
This is a brief

It is known
that alkyl cyclopropaneu isomerize relatively

easily under the
action of a series of catalysts and pass into

an olefin
mixture (Refs 3-5). The authors used kieselguhr for

their
investigation because in its presence ethyl cyclopropane

is
isomerized almost completely at 1200 (Ref 5). Tte experimenis

carried out with vinyl cyclopropane under the same conditions

have shown that quite unexpectedly no piperylene was present

in the catalyst. With the exception of the first few drops
the

catalyzate showed constants of the initial hydrocarbon and

10 % of diene were observed in the catalyzate. It was jbvious
to assume that vinyl cyclopropane is more reaction-;resistant
than ethyl cyclopropane. This was, however, refuted-in the
course of further experiments. It was found that the three-
membered cycle which is conjugated with a double bond may be
isomerized in the presence of kieselguhr. The degree of stabili-
ty of the cycle in this case cannot be determined according
to the amount of the forming piperylene since the latter
completely poisons the catalyst. There are 3 tables and 6
Soviet references.

sure has been investigated. The first series of experiments was
conducted at a degree of dilution of 19-24 H2 ) and at

when the total pressure is increased from 50 to 250 atmospheres
At 3700othe yield of producto changed only Blightly. At 400 0
and 430 the yields increased strongly. The selectivity of "he
process showed only a small change with temperature but decreae-
ed upon an increase in pressure. To clarify the observed affect
another series of experiments was conducted in which the actior.
of the hydrogen and cyclohexane partial pressuren on the con-
version of cyclohexane was observed. Results obtained during ex-
periments carried out at 4300 and 3400 with constant contact
time, partial pressure, and cyclohexane feed rate but with dif-
ferent hydrogen partial prea3ures are given in table 2. It is
seen that the increase in hydrogen partial pressure has only a
small influence on the intensity of isomerizgtion at 430 0,
where-
as this intensity is strongly reduced at 340 - It has been found
that the kinetic order of the reaction with cyclohexane in the
range investigated equals 0.4. Table 3 gives the results of the
series of experiments conducted with cyclohexane at 340 0 and

stant of the reaction at 430 0 does not depend on the hydrogen
partial pressure. The intensification of the isomerizntion ob-
served at this temperature upon an increase in total pressure
is
due to the longer contact time. It has been found that the
logarithm of the rate constant of the reaction at 3400
decreases
linearly upon an increase in hydrogen partial pressure. There

ABSTRACT: In the present paper o- and p-chlorocumenes were
catalyt-ically
dealkylated. The investii-ations were carried out by the
kinetic
method on a device with continuous flow under comparable con-
ditiona: volume of the catalyst 10 ml, temperatures: 370, 410,
450, and 4900, reaction rate: 0.00, 1.60, 3.12 h-1. It was
found that in connection with the cracking of o- and p-chloro-
cumenes under assumed conditions a separation of the isopropyl
group in form of propylene takes place under simultaneous
formation of chlorobenzene. In the analysis of the catalysate
Card 1/3 and crack gases no products were found indicating the

separation of the chlorine atom. In this connection also
secondary reactions take pluce, to a limited extent, which
however, refer to the separated inopropyl group (propylene)
only. Chlorobenzene remains praotic 'ally unchanged so that it
may be considered as the final product of chlorocumene de-
alkylation. The dealkylati.on kinetics of o- and n-chloro-
cumenes are well described by the Frost equation (Refs 6 and
7).
Apparent rate constants and apparent activation energies are
shown in table 1. Figure I shows the kinetics of cracl:inC. On
account of the experimental data found the mechanism of the
dealkylation of chlorocumenes appears to be similar to that
of mono- and dialkylbenzenes. The chlorocumene mixture was
synthetized by means of condensation of isopropyl alcohol
with chlorobenzene in the presence of aluminum chloride
(Ref 8). The mixture was fractioned in vacuum. The results
of the distillation are shown in table 2, the distillation
curve is shomn in figure 2. Fijure 3 shown the dictillation
