Cooligomerization of Styrene and alpha-Methylstyrene Catalyzed by y Zeolites

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 approximate to CaNaY < LaNaY approximate to 0,5NY < LaY < NiHY <= 0,96Y. 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 0,96Y 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.
