Abstract
1,134,318. Ethylene oxide. NAPHTACHIMIE. 21 Aug., 1967 [29 Aug., 1966], No. 38371/67. Heading C2C. Ethylene oxide is prepared by direct partial oxidation of ethylene by passing a gaseous mixture of ethylene and oxygen or a mixture of gases containing ethylene and oxygen at a temperature in the range 150-400‹ C. through a catalytic layer of silver-containing catalysts, the temperature of which increases in the direction in which the gaseous reaction mixture circulates. If desired the catalyst may be divided into two portions maintained at different temperatures increasing in the direction in which the gaseous reaction mixture circulates. The difference in temperature between the two portions of the catalyst is preferably from 5‹ to 50‹ C.
