为了克服以往许多烯烃环氧化催化剂发生严重沉积的缺点,我们首次合成了一种苯乙二醇氧钼螯合物(简称M BC,M为MoO_2,B为苯乙二醇,C为螯合物).将其用于丙烯环氧化新反应中,可以免去助溶剂,苯乙二醇配位体原料可重新由该过程获得,各反应指标均较满意,较好地消除了沉积,表明MBC是个良好的环氧化催化剂. In order to overcome the shortcomings that many olefin epoxidation catalysts have been seriously deposited in the past, for the first time, we synthesized a molybdovanadate chelate (M BC, M is MoO 2, B is styrene glycol, C is chelated Which can be used for the new reaction of propylene epoxidation, can be removed from the cosolvent, styrene glycol ligand material can be re-obtained by the process, the reaction indicators are more satisfactory, the better elimination of deposition, MBC is a good epoxidation catalyst.
