Abstract:

The etherification of ethanol with tertiary carbonic olefins in the FCC light gasoline can not only reduce the olefin content in the oils，but also produce excellent octane enhancer，ethyl tert-alkyl ether. The latest research progress in synthesis of tert-amyl ethyl ether（TAEE）via etherification of ethanol with C₅ tertiary olefins is reviewed. Reactions related to the process including etherification，isomerization，olefin polymerization and hydration are introduced. The tendency of each reaction is analyzed thermodynamically. A comprehensive review of achievements in etherification catalysts，reaction mechanisms and kinetics research is presented. And the future research in this field is also prospected.

摘要：

FCC轻汽油中的叔碳烯烃和乙醇醚化，不仅可以降低油品中的烯烃含量，而且可获得优良的汽油增辛剂乙基叔烷基醚。本文全面回顾了碳五（C₅）叔碳烯烃与乙醇醚化合成乙基叔戊基醚（TAEE）的研究进展，分析了所涉及的醚化、异构化、烯烃聚合以及水合等各类反应，并通过对反应体系的热力学分析，考察了各反应进行的难易程度。同时对醚化催化剂、反应机理及动力学等方面的研究成果进行了综合分析，并对今后该领域的发展方向进行了展望。
