摘要
综述了分子氧氧化苯乙烯制备环氧苯乙烷的多相催化剂研究进展,重点介绍了Co系催化剂在苯乙烯环氧化方面的应用。其中,负载在Beta型分子筛上的Co-Beta催化剂具有较高的催化活性、选择性及稳定性。
The latest research progress in the heterogeneous catalysts for epoxidation of styrene to styrene oxide by molecular oxygen was reviewed, especially cobalt catalyst, among which Co-beta catalysts suppor- ted on beta zeolites exhibited higher catalytic activity, selectivity and stability.
