Aqueous epoxidation process using modified titanium zeolite

摘要

An olefin epoxidation process is described. The process comprises epoxidizing an olefin with hydrogen peroxide in the presence of a modified titanium zeolite catalyst in water solvent. The titanium zeolite catalyst is modified with a platinum, palladium or copper compound. The modified catalyst unexpectedly increases olefin epoxidation activity.
