PROCESS FOR PRODUCING EPOXIDES FROM OLEFINES AND HYDROGEN PEROXIDE OR HYDROPEROXIDES USING A ZEOLITHIC OXIDATION CATALYST

摘要

A kind of method preparing epoxides by alkene and hydrogen peroxide or hydroperoxides uses oxidation catalyst in the liquid phase, is had based on titanium or vanadium silicalite zeolite structured, and wherein the concentration of the hydrogen peroxide in reaction mixture or hydroperoxides is in from 0.05 to less than 1 weight %; % is reacting.
