Liquid phase selective oxidation of epoxides using molecular oxygen

摘要

Problem to be solved: to provide an epoxide method for selectively oxidizing the catalyst by molecular oxygen.Solution: performed in the presence of an epoxidation catalystThe epoxy catalyst comprises 50 wt% to 80 wt% of metal components based on the total amount of the epoxidation catalyst compositionAnd the liquid phase contains perfluoro solventsThe molar ratio of the olefins to the molecular oxygen isCharacterized by a range of 1 to 100 to 100Including the step of performing selective oxidationThe molecular oxygen isSupplied from the vapor phase to the liquid phaseAnd the perfluoro solvent isPerfluoromethyl decarinePerfluorodecarinPerfluoroperhydrophenanthrenePerfluorobutyl tetrahydrofuranAnd selected from the group consisting of themThe metal component contained in the epoxy catalyst is silver;The silver is characterized by at least a portion of the element silver.No selection
