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.
