摘要
The immobilization of molybdenum (Mo) compounds on poly(4-vinylpyridine) (P4VP) microspheres for catalytic epoxidation was reported. P4VP-supported Me compounds were highly efficient and selective for the epoxidation of cis-cyclooctene using hydrogen peroxide (H(2)O(2)) 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 H(2)O(2) and cleaner solvent has been achieved, and the heterogenized Mo catalyst can be recovered for five times without loss of its activity.
