Abstract

A novel catalyst for the manufacture of ethylene oxide from ethylene by means of oxygen or air, comprising from 2 to 12% of silver on a conventional carrier, together with from 0.1 to 2 atom% (based on silver) of lithium and from 0.05 to 0.35 atom% of potassium or 0.003 to 0.25 atom% of rubidium or 0.0005 to 0.2 atom% of cesium or mixtures of potassium, rubidium and/or cesium in amounts exhibiting corresponding catalytic activity. The catalyst is advantageously obtained by heating a carrier which is impregnated with a silver complex compound.
