Study of the Selectivity of Catalysts Used in Dehydrogenal-ior Reac,,Ion of Iscipro-
pylbenzene to Alpha-Methvlstyrene
The Industrial catalyst 1707 and the Cr20 -A1203 catalyst proved to be the most,
advantageous, The aLlthors briefly refer ~o 6e physioo-~-.hemical properties of the
alpha-methylstyrene gionomer. At the catalytl,: dehydrogenatlon of isopropylbenzene
there are, besides tne primary reaction of the formation of alpha-methylsty-rene,
also a series of secondary reactions producing benzene, toluene, sty-rene-ethyl-
benzene, gaseous hyd,~ocarbons, et-c (Fig. 1), The dehydrogeration reaction of
isopropylbenzene is powerfully endothevmic. The quality of catalysts with regard
to the development of a chemical process can be as well appreciated by tak-'rIg in-
to consideration ~,he ELctivlty., selectivity, selectivity index and the apparent
power of activation, The activity increases with the temperature and vice-versa-
The selectivity varies in function of the volumary speed. The temperature reauces
the selectivity, but increases the aotivity. On the basis of Table 8, the authorB
examined five catalysts. Generally, the active component Cr203 presents for a chain
dehydrogenation a reduced selectivity, because 27 - 481% of the raw material are
transformed into secondary products, As compared with the industrial catalyst
1707 (with Pe 0 as active component), a catalyst on the basis of zinc oxide (Zn
2
III) proved to ~e superior. Zn III produces approximately '~IZ alpha-methyl styrene

PERIODICAL: Revista de Chimie, 1960, Vol. 11, No. 11, pp. 626 - '029
TEXT: Subject artic'-e deals with Soviet theories regarding the catalytic
transformation of organic substances, especially of various hydrocarbons. A.A. Ba-
landin,oiith his abhool supports the theory of multiplets, S.Z. Roginskiy, F.F. Vol-
kenstein and I.A. Miasnikov ~.n Moscow, A.N. Terenin and his co-workers in Leningrad.
and V.S. Liashenko with his ,ichool in Kiev have developed the electronic theory of
catalysis. F.F. Volkenstein (Ref. 1) believes that the electronic theory is lead-
ing to conceptsof proper characteristics, Including the existing concepts of the
actual theories. A.A. Balandin expressed his ppinion in a paper presented at the
International Congress on Catalysis in Paris in July 1960 (Ref. 2), according to
which modern theories of heterogeneous catalysis are completing each other. The
electronic theory could contribute to the extension of the theory of multiplets.
Based on this theory the academician A.A. Balandin has worked out the study of the
kinetics and mechanics of the hydrogenation process (Ref. 3). The kinetics of hy-

drogenation were thoroughly studied by S.E. Yelovich and G.M. Zhabrova (Ref. 4).
A.A. Balandin and N.I. Shuikin (Ref. 5) have studied on nickel catalysts the rela-
tive speed of hydrogenolysis of different combinations. The hydrogenolysis of C-C
combinations has been discover(!d by N.D. Zeliriskiy, B.A. Kazanskiy and A.F. Plate.
Based an B.A. Kazanskiyts experimental studies, A.L. Lieberman and A.F. Plate have
accomplished the geometric representation of the process. The kinetics of the
heterogeneous process of the dchydrogenation of cycles with six carbon atoms was
thoroughly studied. The equation of the dehydrogenation speed
(C)
'Id = Kd (C) + (B)
in the presence of metal catalysers has been established by A.A. Balandinand N.I.
Shuikin for the first time. AA. Rubinstein, N.I. Shuikin and their assistants
(Ref. 6) have established that, as more Pt is dispersed in the carbon, the dehydro-
genation synthesis of the cycloliexane agrees with the intensity of X-rays reflected
from the (111) faces. A.A. Baluidin and M. Isaguleants (Ref. 7) recently studied
the dehydrogenation of the cyclohexane (I) and decalin (II) on Ni-Al 203 and

ABSTRACT: A critical discussion of catalytic aluminas. The authors discuss the
structural forms under which aluminum hydroxides and Odes occur and the correlation~
of form with catalytic abtivity; surface chemistry and physical properties are also
examined. Experimental data is cited to show that catalytic activity can be raised
2 to 10 times by influencing isomerization activity through the introduction of
organic surface agents in the precipitation medium. [Based on authors, Eng. abstract]
