MoO2(acac)2 anchored on organic copolymer-inorganic hybrid zirconium phosphonate-phosphate functionalized by pyridines as highly efficient, reusable catalysts for alkene epoxidation

Abstract

The supported molybdenyl acetylacetonate on organic polymer-inorganic hybrid material zirconium poly(styrene-phenylvinylphosphonate)-phosphate (ZPS-PVPA) modified by pyridines, have been synthesized and characterized. The resulting catalysts indicate high activities in the epoxidation of olefins with TBHP as oxidant (conv%, up to >99; sele%, up to >99) whether in experimental scale or in large-scale reactions. Moreover, the catalysts are relatively stable and could be recycled at least ten times without significant loss of activities, which are provided with the potentiality for application in industry.
