| Abstract: Areview is presented on benzene ring alkylation of toluene with methanol for p-xylene synthesis over modified ZSM-5 type zeolites in the last 30 years. There are appropriate channel structure and certain surface acidity in modified ZSM-5 type zeolites. The results showed that the surface acidity is of important to increase the reaction catalytic activity. The reaction mechanism is also evaluated. Total of 145 references is involved. |
