| abstract | D#75,321-1 LGM/?? 6/???6 MODIFIED ETHYLENE OXIDE CATALYST (D#75,312-1-F) ABSTRACT OF THE DISCLOSURE 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 (a) diamines wherein at least one amino moiety is primary or secondary, but no more than one is primary; (b) polyamines containing at least three amino moieties wherein at least one is primary or secondary; or (c) amino ethers containing at least one ether linkage and at least one amino moiety which is primary or secondary; and an effective amount of a salt of cesium; and, heating the impregnated support at temperatures of from about 50°C to about 300°C to evaporate volatiles, decompose the complex and activate the catalyst.
