ABSTRACT:
An improved process for obtaining a silver catalyst promoted with cesium wherein said silver crystals average about 0.4.mu. in diameter and wherein 75-86% of the crystals are within the range of 0.2 to 0.6 .mu. in diameter. This catalyst is prepared without any special heat treatment after the initial reduction of the silver salt and prior to incorporating the cesium promoter.
