1. the manufacture method of a sulfur oxychloride is characterized in that sulfur oxychloride is to utilize sulfurous gas making with gas-phase reaction as in the presence of the catalyzer with activated carbon with monochloride, the dichloride of sulfur subchloride;

  • (1). the building-up reactions of disulphur dichloride is to add SULPHUR POWDER in the gas-solid synthesizer, feeds chlorine again, makes disulphur dichloride gas, and temperature of reaction is controlled at 30-80 ℃

    ;

    (2). the building-up reactions of sulfur dichloride is that disulphur dichloride and chlorine are carried out building-up reactions in convertor, makes in sulfur dichloride gas, and temperature of reaction is controlled at 30-80 ℃

    ;

    (3). the building-up reactions of sulfur oxychloride is to carry out in the catalysis synthesizer, is that catalyzer adds the catalysis synthesizer with the activated carbon, and feeding sulfur dichloride gas, sulfur dioxide gas and chlorine react under 150-280 ℃

    temperature and makes the sulfur oxychloride crude product;

    (4). the crude product product of sulfur oxychloride is squeezed in the still kettle, and distillation makes the sulfur oxychloride elaboration under 75-130 ℃

    temperature, and its purity is more than 98%.
