摘要：

An MCM-22 zeolite with an Si/Al ratio 13 was found to exhibit higher selectivity to beta,beta-diisopropylnaphthalene in the alkylation of isopropylnaphthalene with isopropylalcohol, as compared with other zeolites such as mordenite, Y and beta having similar Si/Al ratios. This high selectivity is ascribed to the specific pore shape of MCM-22 zeolite. The gradual increase in the selectivity with reaction time is due to its port: modification by coke deposit.
