FIELD: industrial organic synthesis catalysts.
SUBSTANCE: invention provides catalyst for oxidation of ethylene into ethylene oxide, which catalyst contains no rhenium and no transition metals and comprises up to 30% silver on solid support and promoter combination mainly consisted of (i) component containing alkali metal on amount from 700 to 3000 ppm of the mass of catalyst and (ii) component containing sulfur in amount from 40 to 100% by weight of amount required to form alkali metal sulfate and, optionally, a fluorine-containing component in amount from 10 to 300 ppm of the mass of catalyst. Ethylene oxide is produced via reaction of ethylene with molecular oxygen in presence of above-defined catalyst.
EFFECT: increased selectivity of catalyst.
