改性X型沸石催化甲苯、甲醇侧链烷基化反应的研究进展

Side chain Alkylation of Toluene with Methanol over Modified X type Zeolites

综述了三十年来国内外有关在改性 X型沸石催化剂上，甲苯、甲醇侧链烷基化制备苯乙烯反应的研究状况。经过改性的 X型沸石具有合适的孔径和适当强度及数量的表面酸碱中心，表面酸碱中心的协同作用有利于反应活性及选择性的提高。参考文献 126篇。

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.
