ABSTRACT:
When supported silver materials are being prepared, deposits of from about 4.0.times.10.sup.-5 to about 8.0.times.10.sup.-3 gram equivalent weights per kilogram of finished product of ionic, higher alkali metals, i.e., ionic potassium, rubidium or cesium simultaneously with the deposit of silver improves the selectivity of these materials as catalysts for ethylene oxide production. Particularly good results are obtained with potassium.
