ABSTRACT:
Many impurities of sulfuryl fluroide are removed by selective adsorption on activated alumina and activated carbon. Thionyl fluoride, hydrogen fluoride, hydrogen chloride, and water are removed by treating contaminated sulfuryl fluoride with activated alumina. Sulfur dioxide and 1,2-dichloroethane are removed by treating contaminated sulfuryl fluoride with activated carbon. When sulfuryl fluoride is treated with the two adsorbents in sequence, sulfuryl fluoride of exceptionally high purity is obtained.
