| Abstract: | The epoxide is a kind of versatile intermediate for manufacture of a wide variety of fine chemicals. The goal of modem efficient catalytic methods is to produce desired compounds with high yield, selectivity, low cost, safety, operational simplicity and more importantly environmentally benign manner. However, there are various oxidants, which are often hazardous or expensive, being used for both laboratory and industrial epoxidation. Hydrogen peroxide (30 wt%) solution is thought as one of the ideal oxidants because water is a sole theoretical side product. Meanwhile the epoxidation of styrene is a typical one among olefins. Here, the performance of styrene epoxidation was studied with hydrogen peroxide solution catalyzed by Co(Ⅱ) phenanthroline complex encapsulated in supercages of MCM-41. |
