ABSTRACT:
A novel cesium modified, activated silver catalyst useful in the vapor phase epoxidation of ethylene with a molecular oxygen containing epoxidizing agent is disclosed. The improved catalyst comprises an inorganic, porous support containing metallic silver and an effective amount of a cesium promoter which have been deposited coincidentally on the support.
The catalyst is prepared by impregnating a porous inorganic substrate with a solution comprising solvent, a silver carboxylate solubilized in an amine-containing complexing agent selected from
