报道了钼化合物在聚4-乙烯基吡啶（P4 VP）微球上的固载化及其催化环氧化反应。P4 VP负载的钼化合物对以过氧化氢（H2 O2）为氧源的顺式环辛烯的环氧化反应具有高效和选择性。以乙醇为溶剂时，含钼催化剂在顺式环辛烯环氧化反应中表现出优异的催化活性和选择性。实现了一种完全绿色的H_2O_2和清洁溶剂的环氧化反应体系，且多相化后的钼催化剂可重复使用5次而不丧失活性。© 2009威利期刊公司. J Polym Sci Part A：Polym Chem 48：558-562，2010
The immobilization of molybdenum (Mo) compounds on poly(4-vinylpyridine) (P4VP) microspheres for catalytic epoxidation was reported. P4VP-supported Mo compounds were highly efficient and selective for the epoxidation of cis-cyclooctene using hydrogen peroxide (H2O2) as oxygen source. When ethanol was used as solvents, outstanding catalytic activity and selectivity were observed for Mo-containing catalysts in the epoxidation of cis-cyclooctene. A completely green epoxidation system based on H2O2 and cleaner solvent has been achieved, and the heterogenized Mo catalyst can be recovered for five times without loss of its activity. © 2009 Wiley Periodicals, Inc.
