Abstract
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.
Claims13
A process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in an oxygenated solvent in the presence of a catalyst mixture comprising a titanium zeolite and a supported catalyst comprising gold and a support, wherein the support is an inorganic oxide containing titanium or zirconium.
