Alkylation of toluene with t-butylalcohol over zeolite to prepare 4-t-butyltoluene is a new technological process. Researchers have paid much attention to this new process because of low raw materials price,high-selectivity for 4-tert-butyltoluene,and products easy to separate. The research progress of reaction mechanism of tert-butylation of toluene,zeolite molecular sieve catalyst and its modification is reviewed. The effects of heteropoly acid,metallic oxide,metallic ion and alkali modification on catalytic performance of zeolite molecular sieve catalyst for tert-butylation of toluene are elaborated. On the basis of maintaining high selectivity and activity,increasing stability of catalyst to make it valuable in industrial application will be the research focus for tert-butylation of toluene in the future.
