Shape-Selective Alkylation of Toluene with Propylene over Modified Zeolite

Abstract:

The shape-selective alkylation of toluene with propylene to produce p-cymene (p-isopropyltoluene) was investigated over parent zeolites and modified zeolites. The catalytic performance was compared over ZSM-5, MOR, SAPO-11, MCM-22 and β zeolite. And, their selectivity was improved by loading of metallic oxides over zeolites, and modified β zeolite showed the highest conversion of toluene and the highest selectivity of p-cymene. Moreover, the reaction conditions were optimized over the modified β zeolite.
