摘要：An improved silver catalyst for the oxidation of ethylene with molecular oxygenis made by impregnating a support with a silver salt prepared by reacting a silvercompound with a neo-acid, in a hydrocarbon solvent with the reaction completed underreflux conditions; drying and activating the resultant precatalyst by heating in air;thereafter impregnating the activated catalyst with an amount, 800 to 5000 wppm ofalkali metal, preferably Cs, to deactivate the catalyst to form a catalyst precursor andheating the catalyst precursor at 450-700°C for 0.1 to 4.5 hours at a steady state in asubstantially inert atmosphere to reactivate it.
