以分子氧为氧源催化苯乙烯环氧化催化剂研究进展

Research progress of epoxidation of styrene with molecular oxygen

环境友好催化烯烃环氧化是催化氧化领域中的一大热点,分子氧作为一种理想的清洁氧源日益受到人们的重视,而分子氧在常温下非常稳定,必须经过适当的催化才能与烯烃发生环氧化反应。本文综述了近年来以分子氧为氧源催化苯乙烯环氧化所用催化剂的主要研究进展,并对其前景进行了展望。

Environmentally benign catalytic epoxidation of alkenes is one of the important applications of catalytic oxidation. Molecular oxygen as an ideal oxidant is used in many catalytic systems. However, molecular oxygen is inactive and it is activated only by the presence of catalyst. In this paper, the recent progress of catalytic epoxidation of styrene with molecular oxygen as oxidant is summarized, and their application is also prospected.
