ABSTRACT:
Sulfuryl fluoride (SO.sub.2 F.sub.2) frequently contains chlorine, sulfur dioxide and other acidic impurities owing to its production. Effective purification is possible if the sulfuryl fluoride is contacted with hydrogen peroxide or a precursor thereof, preferably in an aqueous solution. The purified product is suitable as a pesticidal agent, for example.
