TEXT: The alkylation of isobutane in the presence of aluminum oxide at
high temperatures was investigatedo The experiments were carried out in
the continuous-flow unit described in Ref. 5. The reaction conditions,
degree of ethylene transformation, and alkylate yields are given in
Table 1. The characteristics of the various alkylate fractions obtained
in experiments No. 2 and 4 are shown in Table 2. The fractionation Curve
of the catalyzate obtained in experiment No- 4 is represented in Fig. 1.
Experimental results show that ethylene and propylene react mainly with
the tertiary carbon atom of isobutane, and only to a lesser extent with
its primary carbon atoms. In these reactions, 2,2-dimethyl butane and

Pressure
2-methyl pentane, respectively, are formed. An octane fraction was also
obtained, which was identified to consist mainly of an alkylation product
of 2,2-dimethyl butane. Alkylation at this stage, however, proceeds via
the primary carbon atom at the unbranched end of the carbon chain. This
fact confirms the stepwise character of the alkylation process established
previously (Ref. 8). It was found that in the presence of aluminum oxide
an olefin (ethylene, propylene) is added to the tertiary carbon atom of
isobutane leas easily than to the secondary carbon atom of n-butane.
Yu. P. Yegorov and K. G. Gayvoronskay analyzed the fractions by means of
their Raman spectra. There are 1 figure, 2 tables, and 11 references,
6 of which are Soviet.

TEXT; It has been suggested already earlier that the catalytio activity
of normal calclum phosphate in dehydration- (Ref. 1), hydrolysis- (Ref. 2),
and hydration reactions (Ref. 3) in the vapor phase may be determined by
its acidity. This assumption is substantiated by the fact that the
phosphate catalyzss reactions which in the liquid phase are sped up by
acids ', and that it can be inactivated by potassium carbonate (Ref. 1)1,
alkali hydroxides, or organic bases. The acidity of normal calcium
phosphate is visibly dependent upon the presence cf chemically bound water.
Thus, there must be an interaction between acidity, the catalytic.
activity, and temperature:, wherein the catalyst loses Its crystal water..

TITLE: Method of preparing 2-isopropylanthraquinone
PERIODICAL: Zhurnal prikladnoy khimii, V, 33, no. 8, 1960,
1893 - 1896
TEXT: Recently alkylanthraquinones have been applied as hydrogen
carriers in producing hydrogen peroxide. It has, therefore, been
necessary to look for new methods of preparing these compounds on
an industrial scale. The specific reaction with which the authors
were concerned was to prepare 2-isopropylanthraquinone in two sta-
ges, instead of four as in Scholl's method, which involved react-
ing isopropylbenzene with phthalic anhydride and reducing the re-
sulting 4-isopropylbenzoyl-2-benzoic acid to 4-isopropanyl-benzyl-
2-benzoic acid followed by cyclization of the latter in the presen-
ce of sulphuric acid. To avoid the formation of sulphonic acid

derivatives and to increase the yields of the required quinone the
authors investigated the influence of the oleum concentration, tem-
perature and period of heating, In the case of 3 % oleum and heat-
ing for 1 - 3 hours sulphonation occurred., When the concentration
was increased to 8,% the yield of quinone was 15 %-, however, this
yield decreased when 12 - 20 % oleum was used. The effect of heat-
ing with 8 % oleum is shown, and it is clear that the time of re
action determines the yield of quinone. Best results were obtain;d
with reaction times of 2.5 3 hours, and under optimum conditions
the yield reached 55 - 60 In the earlier investigations the
first stage, condensation of phthalic anhydride with isopropylben-
zene, was conducted in a carbon disulphide mediums The authors,
however, used chlorobenzene as a less hazardous solvent and achie-
ved 88 % yields of 4-isopropylbensoyl-2-benzoic acid. The_quinone
obtained in the present work had a melting point of 56.5 57-00C9
(recrystallized from alcohol) as compared with 450C given in the

TITLE- Catalysis of HYdrogenation Reactions by Zinc
PERIODICAL: Doklady Akademii nauk SSSR, 1960, Vol 131, Hr 5, pp 1109-1112 (USSR)
TEXT: It was established by the authors that the catalytic ef -fect of Z is a
specific one. In hydrogenation and reduction reactions, the hydrogenation of
olefines is not catalyzed by zinc. The hydrogenation of the ethylenic bond
activated by a phenyl group or a conjugated double bond is accelerated by zinc at
elevated temperatures or pressures only. Zn catalyzes the selective hydrogenation
of the acetylenic bond down to an ethylenic bond. The reduction of the C-0 group
of aldehydes and ketones is accelerated to a considerable degree. The results
are in accordance with values calculated for the energy barriers of these
reactions on zinc. Thus, the different order of hydrogenation of bonds on zinc
as compared to the one on other metal catalysts can be explained by the formation
mechanism of an intermediate complex. At present, it is more and more clearly
recognized that the heterogeneous catalytic reaction passes through an adsorption
stage. If both components of the reaction are activated during hydrogenation,
they form a surface intermediate complex with the catalyst. In this case, the
ease of hydrogenation of different intermediate atomic bonds depends on the

height of the energy barrier (-E) of the reaction (Ref 1). In the first place,
the reaction will actually take place which has the least height of the energy
barrier for formation (or decomposition) of the intermediate complex. The
E values can be also calculated from the averages of the bond energies (Q). The
C~C and C-C bonds are hydrogenated more easily on NI than the C-0 bonds. These
reactions proceed in an order analogous to the one established on almost all
known catalysts., As has been stated above, the situation is quite different with
Zn. On Zn, the C=C bond Is not hydrogenated an a rule, the C-0 g=up can be hydro-
genated to give CH-OH, whereas the acetylenic bond is selectively hydrogenated
down to the ethylenic bond. The authors explain the formation of the intermediate
complex on hydrogenation of the ethylenic bond by means of a scheme, and
calculate its heat of formation EO which is -57.9 kcal/mole M. The heats of
formation for the h dro tion of the acetylenic bond down to the ethylenic bond

(E21 = -48.6 kcal I)) and the heat of formation for the complex which
forms when the C-0 group is reduced Nj - -47-4 kcal/mole (III)) are calculated
in an analogous way. It is obvious that for all three reactions El 0
(Ell - heat of decomposition). Thus, the rate of these processes has to be
limited by an adsorption stage (Ref 1). From the calculations performed by the

TITLE: Investigation of the Influence of Composition of Mixed Solvents
on the Rate and selectivity of the Process of Hydrogenationo
2-E At hyylan 'I. hr a quinon a I I
PERIODICAL: Doklady Akademii nauk SSSR, 196o, Vol- 131, No. 6, pp. 1362 - 1365
TEXT: The authors found that the rate and selectivity of the process mentioned
in the title are essentially influenced by the composition of the mixed solvent.
Hydrogenation of the 2-ethylanthraquinone ring is favored by dioxane. At 200 and
normal pressure, one of its two aromatic rings hydrogenates in the dioxane medium.
The authors could not find an octahydro derivative. The formation of the tetra-
hydro derivative starts immediately at the beginning of the process. By addition
of a polar component to dioxane, the reduction of quinone groups is accelerated#
whereas the hydrogenation of the quinone ring is suppressed. On addition of even
small amounts of N,N-dimethyl formamide (0.3~6) to clioxane, 2-ethylanthraquinone
is selectively hydrogenated. A higher selectivity of the process is apparently
achieved by acceleration of the hydrogenation of the quinone group and by

adsorptive substitution of the hydroquinone molecules. The degree of selectivity
depends on the nature and quantity of the polar solvent added. In their exyeri-
ments, the authors used the following solvent mixtures: dioxane-N,N-dimethyl
formamide and dioxane ethanol. The catalyst was produced by treating a Ni- 11
alloy (50:50) ivith alkali. The reaction rate was determined by measuring the ab-
sorption rate of hydrogen. The quinones were determined after oxidation of the
catalyzate by means of air with automatic photopolaTOgraphe of the type LP-55
(Methods, Ref- 4)- Preliminary experiments showed that the reaction rate does
not depend on the intensity of stirring. The reaction order in dimethyl forms-
mide was equal to zero (Fig. 1). Fig. I shows the dependence of the hydrogena-
tion rate of 2-ethylanthraquinone on its concentration in dimethyl formamide.
Fig. 2 shows the dependence of the absorption rate of the first mole of hydrogen
on the composition of the binary solvent. Table I shows that the reaction pro-
ceeds least selectively in dioxane. Already under smooth experimental conditions
(200, normal pressure), 2-ethyltetrahydroanthrahydroquinone begins to form'. On
hydrogenation in 90~ of dioxane and 10A of ethanol (or equal volumes of dioxane
and ethanol), no tetrahydroquinone was detected even after absorption of
0.95 mole of hydrogen. There are 2 figures, I table, and 4 references, 3 of which

pressure of 100 atm. The reaction products were divided into three
fractions: 1) hexamethylene imine (boiling point 137 0C, boiling point
of the azeotropic mixture with water 95 0C); II) hexamethylene diamine
boiling point 95 - 1020C at 20 mm HI)l and III) &-amino capronitrile
~boiling point 118-120 C at 20 mm Hg . The high boiling residue w&s
composed of non-reacted dinitrile and of bia-hexamethylene triamine.
A Ni-Ti-Al skeleton catalyst and a nickel boride catalyst manufactured
by the following method were used; A 20% aqueous solution of sodium
boron hydride was added in an amount of.60 ml to 250 ml of a 10% aqueous
solution of nickel chloride in such a way that the temperature did not
surpass 500C. This catalyst was modified with chromium by adding, more-
over, 10 ml of a 10-30% chromium nitrate solution to the solution of the
nickel salt. Results are listed in Tables 1 and 2. Furthermore the
hydrogenation of the reaction products has been studied (Table 3~. The
following conclusions were drawn from these data: The selectivity of the
nickel-skeleton catalyst increases with increasing content of titanium.
On the nickel boride catalyst, a selective hydrogenation of the dinitrile
to amino-nitrile takes 0place. Under optimum conditions (20 catalyst,
presence of NHY 75-80 C, PH 2 - 95-100 atm) 50-60% amino nitrile and

only '2-5% diamine are formed. The'incomplete conversion of the dinitrile
is due to the fact that amino nitrile excludes it from adsorption. Cyclo-
hexamethylone imine is formed only in the second stage of the process.
The formation of 'bis-hexamethylene triamine increases if a mixturo of di-
nitrile afid hexamethylene diamine is hydrogenated. As in the case of other
catalysts, ammonia suppresses the formation of secondary &mines. Those
facts confii~m-the aldimine mechanism of the hydrogenation of dinitrile.

TEXT: The synthesis of dienes by selective catalytic hydrogenation of the

the present time, primarily on the hydrogenation of dimethyl vinyl
ethynyl carbinol. Following their study (Ref. 7: 1,-,v. AN SSSR, Otd.

methyl vinyl ethynyl carbinol with addition of 1 tG 3 moles of hjdrogen

had not been developed so far, the content of' earbiriol in the fractions Was
determined according to the amount of vinyl acetylene which forms due to
the effect of metallic sodium. In the presence of the nickel skeleton
natalyst, the addition of one nole of hydrogen to dimeth:.rL vinyl ethynyl
carbinol does not proceed selectively: A mixture forms, which contains
the initial carbinol as well an the diene and ethylene Ulcohol. The
partial poisoning of the catalyst surfa,3e by pyridine did not result in a
considerable increase of the yield in diene alcohol. In the presence of
the zinc skeleton catalyst, dimethyl vinyl ethynyl carbinol is hydrogenated
selectively to form dimethyl butenyl carbinol. After addition of onemole
of hydrogen, the catalyzate contains about 70 % of diene alcohol. Thun.
the zinc catalyst develops the highest selective activity in this reaction.

TEXT: Up to the present time, the alkylation of cycloparaffin hydro-
carbons has hardly been studied. H. Pines and N. Ipatieff (see below)
studied the alk lation of methyl cyclopentahe with olefins in the presence
of H2so 4 (100;6~ or HF. The reaction proved to be very complicated.
Yu. G. Mamedaliyev and A. Kuliyev (Dokl. AN SSSR, 88, 471 (1953)) as well
as Yu. G. Mamedaliyev and Z. A. Mamedova (ibid., 172, 1063, (1957))
alkylated methyl, ethyl, and isopropyl cyclohexane with propylene and
butylene under similar conditions. In the present study, the direct
alkylation of cyclopentane with ethylene and propylene at elevated
temperatures and under pressure was achieved for the first time. The
main reaction products were iaolated and identified. The influence of

temperature and pressure on the course of reaction was studied. The
alkylation with ethylene proceeds already at a temperature of 3500C and
under a pressure of 200 atm. At elevated temperaturesand pressures, the
yield in alkylates and the degree of oonversion increase. At 45000, the
ethylene was completely consumed. Diagram I shows the chromatogram of
one of the eatalyzates with carbons up to 09, and also its distillation
curve. The main reaction products were ethyl cyolopentane (peak III),
the diethyl oyclopentanes (peaks IV and V), anJ butyl cyclopentane
(peak VI). A horizontal section on the distillation curve corresponds
to each of these peaks. After elimination of the oyclopentane from the
alkylate by fractional distillation, the follo-ming fractions were obtained-
1) monoethyl cyclopentane and II) diethyl cyclopentane. The unsaturated
character of the alkylate is not strongly marked. The yield in ethyl
cyclopentanee amounts to 36 % (related to the reight of the alkylate) and
to 65 % (related to the weight of the large fraction). Alkylation with
propylene is more difficult. On distillation under pressures between 200
and 450 atmo easily boiling cracking products, the fraction of propyl
cyclopentane, and the higher boiling residue were separated from the

leaching,powdered 506 nickel-aluminum- and cobalt-aluminum alloys with 10%
aqueous NaOR solution. The catalysts were then washed with water up to
neutral reaction against phenolphthalein. Cobalt skeleton catalyst
leached with 25-3W6 aqueous alkali solution at maximally 150C (Rof- 5: see
below) was used in some experiments. Diamine*yields are strongly
influenced by the nature of the catalyst and its preparation method. The
yield is 64-65% in the case of nickel skeleton catalyst, 74% with cobalt
skeleton catalyst leached at 900-1000C, and 94% with catalyst prepared by
"cold leaching". The authors also studied the polycondensation of
p-(P,pl-diamino-diethyl) benzene with adipic acid and terephthalic aoid.
Addition of acetone to an equimolar mixture of aqueouti diamine- and adipic
acid solutions precipitates the salt. This salt is crystallized twice from
water, yielding a white crystalline substance, m.p. 2000-2020C
(C16H26N204). The polyamide was obtained by polycondensation of thin salt
at 2600-2800C. Polycondensation occurs in the solid phase below the
melting point of the polyamide. This polyamide based on p-(P,PI-diamino-
diethyl) benzene and adipic acid was also prepared at 200C by heterophase
polycondensation: reaction between the aqueous diamine solution (with
sodium carbonate added) and adipic chloride in benzene. Polyamides were

also prepared in an analogous manner by reaction of terephthalic- and
sebacic chlorides in methylene chloride with aqueous diAmine solutions
containing alkali to bind the hydrochloric acid formed according to the
method by P. W. Morgan (Ref. 6, see below). In all experiments, poly-
condensation of adipic acid with the diamine under investigation yielded a
polyamide having a melting point of 3140-3200C. It is soluble in
concentrated H2 so 4' cresol, formic acid, hydrochloric acid, and insoluble
in organic solventi. Polyamides of higher.mol wt. are obtained by increasing
the reaction temperature and reaction time. The relative viscosity of
these polyamides in concentrated H2so4 is increased from 1.73 to 2.69. By
spinning these high-molecular polyamides from their melts at 3350-3400C
fibers capable of orientation at high temperatures were obtained. The
polymer properties are also affected by the purity of the amino Galt used..
If the salt is only recrystallized once, colored polyamides of lower
molecular weight are formed. There are 2 tables and 8 references:

TITLE~ Theri:;al alkylation of methylcyclohexane with oief3.zis
undez- pressure
PERIODICALi Neftekhimiya, v.1, no.5, ig6i, 613-618
TEXT: The authors reported recently that alkylation of cyclo-
hexane and cyclopentane can be achieved thermally (350 to 450"C)
under pressure (50 to 200 atm). Further work on alkylation of
methylcyclohexane with olefins was carried out to elucidate the
influence of side chains on the direction and ease with which the
reaction proceeds,, The reaction was carried out in a reactor
filled with quartz rings. Molar ratios of methylcyclohexane to
ethylene were from 2.5 to 3.6 and for propylene 1.4 to 3.2. The
space velocity varied between 0.81 and 0.99 litre/hour for
ethylene and 0.52 to 1.43 litre/hour for propylene, All
experiments with propylene were carried out at 4501C, whereas for
ethylene the temperatures varied from 350 to 4500C. Results show
that the main product of the reaction of methylcyclohexane with

ethylene is a mixture of methylethylcyclohexanes? the proportions
of various isomers differing from their equilibrium concentrations.
With propylene the reaction proceeds with more difficulty and the
yield of alkylate is lower than that obtained for ethylene
(155% of propylene taken and 316% of ethylene respectively).
Comparison with previous work (Ref-7: N.M.Nazarova, L.Kh.Fre:ydlin.
Dokl. AN SSSR, 137, 19611 1125) shows that the alkylation of methyl-
cyclohexane proceeds more easily than that of unsubstituted cyclo-
hexane. The reaction begins at a lower temperature (3500C) and
pressure (50 atm). The expected formation during the reaction of
1-methyl-l-ethyleyclohexane was not observed, which is explained
by thermal instability of hydrocarbons with quaternary carbon atoms.
It is postulated that 1,3 and 1, 4-isomers are formed by an internal
rearrangement of 1,1-isomer or via an intermediate stage of
migration of free valency of methylcyclohexyl radical from
position 1,1 to positions 1,3 and 1,4. Acknowledgments are
expressed 'to A.L.Liberman and T,V.Vasina for supplying the
methylethylcyclohexane samples. Yu.G.Mamedaliyev, Aladdin Kuliyev

TITLED Alkylation of cycloparaffinic ring in tetralin with
olefins
PERIODICALI. Neftekhimiya, v.1, no,5, ig6i, 61g-.623
TEXT!, It was observed recently that alkylation of cyclohexane can
be accomplished under conditions (high temperatures and pressures)
at which benzene is not alkylated. It was expected therefore that
the saturated ring in tetraline will be selectively alkylated under
similar conditions. The experiments were carried out in a flow.
apparatus described previously (Ref-5: Dokl. AN SSSR, v.37, no.5,
1961, 1125), the reactor (120 ml) being filled with crushed quartz .
Tetraline used had a boiling point 78"C/12 mm Hg, djO 0.9677 and
n20 t
D 1.544o. The ethylene contained 7% ethane, he propylene
contained 12% propane. The reaction with tetralin was studied at
400 and 4500C and 50 to 200 atm pressure. The reaction with
propylene was conducted under optimum conditions for the
alkylation with ethylene, i.e. 1150"C, initial pressure of 200 atm
and mole ratio of tetralin to propylene of 2-3. The degree of

conversion of propylene in one cycle was 51% and that for
totraline 29%. The yield of alkylate was 150% of propylene mixed
with tetralin. Products obtained by the alkylation with ethylene
are given in Table 1. The main product Is I-ethyltetralin.
The products of the reaction with propylene are mainly mixed
propyltetralins. It was not possible to obtain any information
about the structure and position of the side chains in the
constituents of the mixture but it is expected that mainly
1.-.n propyltetralin is formed. Acknowledgments are expressed to

TITLE: Studies of atepwise dehydration of glycols on the
tricalcium phosphate catalyst
PERIODICAL: Doklady Akademii nauk SSSR, v. 136, no. 5, 1961, 1108-1111
TEXT: The authors dehydrated several diole on the tricalcium phosphate
catalyst (for its production see Ref. 11) in a wide temperature range.
1) 5, 20, and 49% of trimethylene glycol was converted at 250t 300, and
3500C, respectively. and gave allyl alcohol and propionaldehyde as the
main products. No trimethylene oxide was found, but the authors assume
that while this oxide does form, it is quickly isomerized to the two
afore-mentioned end products. 2) Butene-2-diol-1,4 60% of which were
converted at 2800C. The main products were: 2,5-dihydrofuran and
crotonaldehyde, Butene-2-diol-1,4 is dehydrated mainly under oxide
formation. 03) Butanediol-1,4 yields only 98% tetrahydrofuran between
260 and 320 C. At temperatures above 3200C the yield of tetrahydrofuran
drops, giving at the same time buten-2-ol-4, divinyl, and butyraldehyde.

Dehydration of tetrahydrofuran to divinyl sets in above 3800C.
4) Pentanediol-1,5 is selectively dehydrated to tetrahydropyran
(72% yield) between 280 and 3430C. At higher temperatures also pentenoles
and pentadienes are formed (the latter result from tetrahydropyran at
389-41800- 5) Hexanediol-196 with the reaction products: hexamethylene
oxide, hexenols, and hexadiene-195. On hydrogenation, the latter
absorbs 2 moles H2o At the same time, the following isomerization
products are formed: a-methyl tetrahydropyran, a-ethyl tetrahydrofuran,
hexadiene-1,4, and others. 6) 3,7-dimethyl octanediol-1,7 ia 0
selectively dehydrated to oitronellol (84% yield) in vacuo at 200 C.
Only 5% diolefin is formeC At higher temperatures the quantitative
ratio of these end products becomes reverse (90% diolefin at 2900C).
Under these latter conditions citronellol is dehydrated to diolefins
with about the same yield as the diol. The above results enabled the
authors to judge the influence of the glycol structure upon the reaction
direction, the conditions under which glycols are only partly dehydrated
to oxides, and the ways of a complete dehydration to a diene-
hydrocarbon. C 4 and C5 glycols are selectively dehydrated to oxides

between 280 and 3200 C. The oxacyclanea resulting as intermediates are
formed more and more difficultly in the order C4 >C5>C 6* Tetrahydrofuran
18 formed in higher yield and at lower temperatures than tetrahydropyran,
the latter being obtained more easily than-hexamethylene oxide. Abolve
3200C, also unsaturated alcohols and diolefin hydrocarbons requ'lt. The
authors further conclude *from the results obtained that oxacycIanes,ire
more difficultly dehydrated to diolefins than the corresponding glycols.
The intense formation of diolefin above 3500C with simultaneousjy irkoreas-
ing yield of hexamethylene oxide, and decreasing yield of hexenol is~
regarded by the authors as proof for the fact, that diolefin mainly '
results from hexenol which is less stable than the oxide. Hence, the
a,.-glycols C4 ~C6 zre gradually dehydrated. The following compounds
are obtained: in the 1st stage - oxacyclane, in the 2nd stage - an
unsaturated monovalent alcohol isomeric to oxacyclane (lower formula);
in the 3rd stage - the end product, a diolefin, which mainly resulte.via
stage II, and not from the oxide I (upper formula).

TEXT: The carbonylation of aliphatic amines in the presence of Ni and Co
halides was studied. The amines Yfidah were used: L7b2H5)2NUI (so_44H9)21'M2
Y9N"21 Mi 2 and H-CO3,3N"27 have identical dissociation constants.and form
carbonyls almost identically. At a temperature lower than 266' C, the main direc-
tion of the process is toward the formation of formamides. At a temperature higher
than 260P C,,amines deaminate and deal1kal_tze., and formamides decompose. The olefins
which are formed in this process interact with CO, and NH , forming carboxylic acid
amides. In this manner, the carbonylation process of ;2nes goes in two directionst
formation of formamides and formation of amides of c-arboxylie acids. Author's ab-

dehydration of primary alcohols .
PERIODICAL: Noftekhimiya, v-3, no.1, 1963, 10-12
TEXT: The authors investigated the catalytic dehydration of C8,
CIO and C12 n-alcohols after previous successful preparation of
98!; pure a-olef-Ins from n -Ci,- C6 alcohols using trisubstituted
calcium phosphate as catalyst (Neftekhimiya, v.1, no.6, 1961, 749).
The catalyst was prepared by treating the phosphate with 0.07 9
NaOll/g catalyst and baking at 400 to 450"C. for 1 to 2 hours.
It preserved its activity without regeneration. The products of
the dehydration were 92 to 94% pure a-olefins (97 to 98% after
distillation) obtained with'the.yields of 58 to 88%. The purity
of the alcohols is of the same order as that obtained after the
pyrolysis of the acetates and is much bettor than that of the
alcohols produced with alumina an the dehydration catalyst. In
the latter case the products contain only 39 to 613% a-olefinz and
