苯烷基化的研究进展

Research Progress of the Alkylation Reaction of Benzene

芳烃烷基化反应是在催化剂作用下将烷基引入芳环上的反应过程,是有机合成中的一类重要反应。针对苯与甲醇、乙醇和烯烃等不同烷基化试剂的芳烃苯烷基化反应机理、热力学过程、反应条件优化、及对ZSM-5等催化剂的金属、非金属、稀土元素的改性进而改变催化剂的骨架结构、孔道、酸强度、酸量等特征的应用进行了阐述,更深入的理解芳烃苯烷基化在有机合成中的应用和地位。

The aromatic alkylation reaction is a reaction process in which an alkyl group is introduced into an aromatic ring under the action of a catalyst, simultaneously, that is significantly typical in organic synthesis reaction. In this paper, in terms of various aromatic alkylation reagents, aromatic alkylation reaction was described, especially, the alkylation of benzene and different reagents including methanol, ethanol, and olefins;meanwhile, the reaction mechanism, thermodynamic process, optimization of reaction conditions and catalyst modification were expounded. The application of ZSM-5 catalyst and others modified by rare-earth element, supported metal, and supported non-metal was studied.
