Abstract

It is ascertained that during the interaction of styrene and -methylstyrene in the presence of cation and cation-decationated forms of zeolite Y the activity of zeolite catalysts increases in the following order: NiNaY CaNaY <LaNaY 0,5 NY <La Y <NiHY 0,96 Y. The product of reaction in the presence of cation forms of zeolite (NiNaY, CaNaY, LaNaY) is a mixture of low-molecular (n=2 - 4) and high-molecular oligomers (n=14). Oligomers with the degree of oligomerization 2 - 8 are formed in the presence of other zeolite samples. Zeolites 0,96 Y and NiHY allow to receive gomo - and codimers with selectivity 68-80%. The main product of codimerization is cyclic dimer 1,1 – dimethyl – 3-phenylindane.
