Bisphenol S Application
1. Mainly used as fixing agent.
2. Can be used as plating solution additive, leather tanning agent, dispersant for high temperature disperse dyeing, phenolic resin hardening accelerator, resin flame retardant, etc.
3. Intermediates for pesticides, dyes and additives.
4. The substitute of bisphenol A can be used as the raw material of polycarbonate, epoxy resin, polyester, phenolic resin, and the raw material of polysulfone and polyethersulfone.
5. It can be used to manufacture color photographic materials, contrast contrast enhancers, thermal recording materials (color developing agents), daily surfactants and high-efficiency deodorants.
6. Fixing agent A can be prepared with bisphenol S as raw material (foreign trade name is CibatexPA).
Bisphenol S molecule contains two hydroxyl groups and a strong electron-withdrawing sulfone, acidic than other phenols.
Bisphenol S mainly used as a fixing agent. Fixing agents can be produced for raw material with bisphenol-A. It has excellent heat resistance, light resistance, and oxidation resistance, is polycarbonate, epoxy resin, and polysulfide, polyethersulfone, polyether resin raw materials, etc.
