Abstract
Highly selective and productive epoxidation catalysts are prepared by combining a titanium zeolite, palladium, and a gold promoter. The resulting materials are useful catalysts for transforming olefins to epoxides in the reaction of an olefin, hydrogen, and oxygen.
Claims18
A process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in the presence of a catalyst comprising a titanium zeolite, palladium, and a gold promoter.
A method for preparing a catalyst comprising the steps of:
- (a) impregnating a titanium zeolite with a solution of a palladium compound and a gold compound in a solvent;
- (b) removing the solvent from the impregnated titanium zeolite;
- and
- (c) drying the impregnated titanium zeolite.
