| Abstract: A review is presented on side-chain alkylation of toluene with methanol for styrene synthesis over modified X-type zeolites in the last 30 years. There are appropriate channel structure and certain surface basicity and acidity in modified X-type zeolites. The results showed that the coordination of acidity and basicity is of important to increase the reaction catalytic activity. The reaction mechanism is also evaluated. Total of 126 references is involved. |
