Verfahren zur Herstellung von Epoxiden aus Olefinen und Wasserstoffperoxid oder Hydroperoxiden

摘要

A process for producing epoxides from olefines and hydrogen peroxide or hydroperoxides in the liquid phase using an oxidation catalyst based on titanium or vanadium silicalites with a zeolithic structure, in which the concentration of the hydrogen peroxide or hydroperoxides in the reaction mixture is in the range from 0.05 to less than 1 wt.% during the reaction.
