DIRECT EPOXIDATION PROCESS USING A MIXED CATALYST SYSTEM

摘要

A catalyst mixture containing a titanium zeolite and a supported gold-containing catalyst is highly selective and productive for transforming olefins to epoxides in the liquid-phase reaction of an olefin, hydrogen, and oxygen. This is particularly surprising because neither titanium zeolite nor the supported gold-containing catalyst alone is effective in olefin epoxidation.
