摘要
The liquid-phase epoxidation reaction of an olefin with hydrogen and oxygen in the presence of a catalyst mixture comprising titanium zeolite and a supported catalyst surprisingly shows higher activity toward epoxide production when the supported palladium catalyst is pre-treated with bromide, or where the reaction is performed in the presence of an alkali or alkaline earth metal bromide compound.
