MCM-22 hydrothermally treated at 873 K exhibits a great improvement in ethylbenzene selectivity along with a slight decrease in benzene conversion, corresponding to the proper acidity strength of the catalyst. It indicates that alkylation of benzene with diethyl carbonate mainly occurred on Brønsted...
