摘要：

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 beta zeolite. And, their selectivity was improved by loading of metallic oxides over zeolites, and modified p zeolite showed the highest conversion of toluene and the highest selectivity of p-cymene. Moreover, the reaction conditions were optimized over the modified beta zeolite.
