稀散金属铼功能材料的设计合成及催化烯烃环氧化

Design & Synthesis of Rhenium Functional Compounds and Its Catalysis in Olefin Epoxidation

在前期研究基础上,以席夫碱为配体,合成了改性MTO配合物,将其应用于烯烃的环氧化反应,效果良好.根据催化历程,采用分子设计,合成了对空气和湿气稳定的铼离子液体,应用于同一体系,效果极大地超越同类催化剂,实现了99%以上的选择性和较高的产率.

On the basis of our previous investigation, we synthesized modified MTO Schiff- Base Complexes, which could be applied in olefin epoxidation with good performance. According to the catalysis mechanism, we also designed advanced rhenium ionic liquids which were stable in air and moisture. The synthesized rhenium ionic liquids were applied in the same catalysis system, and it was proved high yields with selectivity above 99% ,which surpassed other similar catalysts.
