Abstract:
An investigation has been made of the catalytic activity of pentasil-type zeolites of different structure and chemical composition in the alkylation of xylenes and pseudocumene by methanol. It has been shown that the steric constraints imposed by the zeolite used make it possible to control the number of substituents in the benzene ring and the isomeric composition of the reaction products. By changing the concentration and strength of the acid centres in the zeolite, it is possible to influence the selectivity of the process by virtue of the fact that, in contrast to the rival reaction of methanol conversion, alkylation is retarded by the diffusion of aromatic hydrocarbons. The process of producing 1,2,4,5-tetramethylbenzene by the alkylation of pseudocumene with methanol on an iron silicate zeolite has been optimized with the aim of achieving indices acceptable for industrial practice
