Abstract: A process for the epoxidation of alkene to form alkene oxide comprising contacting alkene and oxygen- gas under epoxidation conditions in the presence of a performance-enhancing gaseous halide, e.g., ethyl chloride, at least one gaseous efficiency-enhancing member of a redox-half reaction pair, e.g., nitric oxide, and a supported silver catalyst, the catalyst comprising a catalytically-effective amount of silver and an efficiency-enhancing amount of at least effi- ciency-enhancing salt of a member of a redox-half reaction pair, e.g., potassium nitrate, wherein the gaseous halide and the gaseous efficiency-enhancing member of a redox-half reaction pair are provided in such amounts and the ratio of which are such that the activity and/or the efficiency of the process are enhanced.
