ABSTRACT:
When supported silver materials are being prepared, deposits of ionic, higher alkali metals, i.e., ionic potassium, rubidium, cesium or combinations thereof on porous supports with surface areas ranging from 0.1 to 7 square meters per gram prior to the deposit of silver improves the selectivity of these materials as catalysts for ethylene oxide. Optimal concentrations of the ionic, higher alkali metals are directly proportional to the surface area of the support.
