摘　　要：环氧丙烷(PO)是重要的有机化工原料,主要用于生产聚醚多元醇、丙二醇和各类非离子表面活性剂等。综述近年来催化丙烯选择性环氧化制备环氧丙烷的研究进展,包括以氧气、H_(2)O_(2)、原位合成H_(2)O_(2)和有机过氧化物为氧化剂的催化工艺,并展望催化丙烯环氧化的绿色催化工艺和研究方向,未来需重点研究仿生催化、原位合成H_(2)O_(2)、高选择性催化剂的设计和催化反应机理等。Propylene oxide(PO)is an important organic chemical raw material,which is mainly used to produce polyether polyols,propylene glycol,various non-ionic surfactants,and so on.The research prog-ress on catalytic selective epoxidation of propylene to propylene oxide in recent years were reviewed in this paper,including the catalytic processes with oxygen,H_(2)O_(2),in situ generation of H_(2)O_(2)and organic peroxides as oxidant.Green catalytic process for preparing propylene oxide in the future were expected.It is necessary to focus on the propylene epoxidation process of biomimetic catalysis,in situ H_(2)O_(2),design of high selectivity catalyst and the catalytic reaction mechanism.
