Diphenyl Sulfone CAS 127-63-9 Purity >99.5% (GC) Factory

Diphenyl Sulfone (CAS: 127-63-9) is a sulfone compound having two S-phenyl substituents. Diphenyl Sulfone was identified as the preferred solvent. Diphenyl sulfone is chemically and thermally stable as compared to dimethyl sulfoxide. It is used as a high temperature solvent. Such high temperature solvents are useful for processing highly rigid polymers, e.g., PEEK, which only dissolve in very hot solvents. Used for sensitizer for thermal paper, polyether sulfones, polysulfone resins, and fire retardant; Used in organic synthesis, as plasticizer and acaricide; Used as intermediates of pharmaceutical and pesticide. Used as an additive for plating solution, leather tanning agent, dispersant for high-temperature dyeing of disperse dyes, hardening accelerator for phenolic resin, flame retardant for resin, etc. Used as a color fixing agent. Used in the synthesis of leather fuel, polymer monomer. As a substitute for bisphenol-A, it can be used as a raw material for polycarbonate, epoxy resin, polyester, phenolic resin, and polysulfone, and polyethersulfone. Used as analytical reagent, solvent, also used in the preparation of spices and enteric insecticides. Permitted flavorings for food according to GB 2760 -- 1996.Mainly used for the preparation of vanilla, fennel and beer flavor. Used as a solvent for recrystallization, thermostat filler, refractive index measurement, perfumery, intermediate for organic synthesis.
