摘　　要：结合作者的研究工作,概述了噻吩及其衍生物的应用前景,着重综述了实用性强、环保、经济可行的萃取精馏+吸附;萃取精馏+反应精馏;萃取精馏+离子液体络合萃取等新型组合工艺,对合理利用噻吩资源,减少焦化苯精制中的环境污染等具有十分重要的意义。Thiophene and its derivants are very difficult to be removed by coking light benzene purification. Meanwhile they are important raw materials for making medicines, catalysts, etc. This paper, integrates the author＇s progressive researches and summarizes the application prospect of thiophene and its derivant. The emphasis of the review is put on the practical, environmental, economical and new technologies such as extraction distillation plus adsorption, extraction distillation plus reactive distillation and extraction distillation plus ionic liquids coordination extraction. It is of great significance to the appropriate utilization of thiophene resources, and to the reduction of environmental pollution in refining coking benzene.
