THE METHOD OF PRODUCING CHLORINE OXIDES HIGHER THAN THE MONOXIDE WHICH COMPRISES EXPOSING A STREAM OF CHLORINE AND OXYGEN IN A REACTION ZONE TO A NON-LUMINOUS DARK ELECTRIC DISCHARGE UNDER CONDITIONS OF RELATIVELY LOW FREQUENCY OF ABOUT 10 TO 10,000 CYCLES PER SECOND AND AT A RELATIVELY LOW VOLTAGE-AMPERAGE RELATIONSHIP WITH LOW HEAT AND LIGHT PRODUCTION, RECOVERING THE REACTION MIXTURE, AND REMOVING UNREACTED CHLORINE AND OXYGEN FROM THE REACTION MIXTURE.
