Abstract

Ethylene oxide is produced by the partial oxidation of ethylene by means of gaseous oxygen in the presence of a silver-containing catalyst, which comprises operating with a concentation of oxygen in the range 1-10%, a concentration of ethylene of 1-30%, a concentration of carbon dioxide of 0.1-10%, a concentration of halogenated inhibitor of 0.0001-100 p.p.m., a concentration of ethane and/or ethane in the range of 0.001-40%, a reaction temperature of 150-400 DEG C., a reactor pressure of 50-650 p.s.i.g., a flow rate of 50-1500 standard cu. ft./hr., a reaction zone average diameter of 0.5-2.0 inches and length of 5-40 ft., the conditions being controlled to give a selectivity of 60-80% and an ethylene oxide concentration in the exit gases of 0.3-5%. The percentages given, where appropriate, are percentages by volume. The preferred inhibitor is ethylene dichloride.
