摘要：

Selective synthesis of ethylbenzene by vapor phase alkylation of benzene with diethyl carbonate was carried out over MCM-22 modified by MgO. Characterization results show that the number of Brønsted acid sites on MCM-22 decreased significantly after MgO modification, which resulted in a decrease in activity. The selectivity for ethylbenzene was improved greatly over MCM-22 modified by MgO, which can be attributed to the effective suppression of subsequent alkylation of ethylbenzene by the reduction in Brønsted acid sites.
