Abstract

A catalyst for the manufacture of ethylene oxide, giving improved yield and having a long life, based on an alkali metal-modified silver catalyst on an oxide carrier is obtained by providing the silver-containing catalyst, in the reduced state, with the alkali metal by applying an alcoholic alkali metal salt solution which also contains an organic oxygen compound or nitrogen compound which forms complexes with silver ions.
