PURIFICATION OF SULFURYL FLUORIDE.

摘要

Sulfuryl fluoride can be used as an insulation gas in electrical devices or pesticides. It often contains sulfur dioxide, hydrogen fluoride and hydrogen chloride. An effective purification is possible when the sulfuryl fluoride so contaminated is guided over alkali fluoride. Purification can be carried out during production, storage, but also before or during use of the sulfuryl fluoride as, for example, pesticide.
