APPLICATIONS

Sulfoxide (R2SO) is any of various organic sulfur compounds having the group -SO (sulfinyl group) whereas sulfone (RSOOR') with the group -SO2 (sulfonyl group). They are derived from oxidation of sulfides. In pharmacological medication application sulfone is a basic structure in preparing sulfonamide antibacterial agents. In polymer industry it is a structure in the production of engineering plastics and water soluble polymers. Sulfone-containing engineering plastics are thermally stable and have high resistance property to acids and alkalis. Some sulfone derivatives are used as a flame retardant that can be chemically inserted into the polymer molecule or be physically blended in polymers after polymerization to suppress, reduce, delay or modify the propagation of a flame through a plastic materials. Potassium 3-(phenylsulphonyl)benzenesulphonate is an example of sulfone class flame retardant.

4,4'-Dichlorodiphenyl sulfone, chlorinated organosulfone, is used as an intermediate in the preparing of epoxy hardners, engineering plastics, and pharmaceuticals (antibacterial agents, antileprotic drugs).
