Bis(4-hydroxyphenyl) Sulfone Usage And Synthesis
Chemical PropertiesWhite needle-like crystals. Freely soluble in aliphatic hydrocarbons, soluble in alcohols and ethers, slightly soluble in aromatics, insoluble in water. Bisphenol S molecule contains two hydroxyl groups and a strong electron-absorbing sulfone group, so the acidity is stronger than other phenols.
Uses4,4'-Sulfonyldiphenol is commonly used as a reactant in epoxy reactions and is also used as a latent thermal catalyst for epoxy resin.
UsesBis(4-hydroxyphenyl) Sulfone is commonly used as a reactant in epoxy reactions and is also used as a latent thermal catalyst for epoxy resin.
PreparationA process for the preparation of bis(4-hydroxyphenyl)sulfone by reacting phenol with sulfuric acid in the presence of a solvent at from 130° to 220° C and in the presence or absence of a sulfonating assistant. 
Definition4,4'-Sulfonyldiphenol is a sulfone that is diphenyl sulfone in which both of the para hydrogens have been replaced by hydroxy groups.
General DescriptionBisphenol S (BPS), belonging to the class of bisphenols, is a structural analog of bisphenol A (BPA), used in a variety of industrial applications and products marketed as BPA-free. It is commonly identified in food and beverages, environmental samples, biological matrices, etc. It is also reported to be used in the production of epoxy resins. BPS is also found to be stable compared to BPA at elevated temperature and sunlight conditions.
Health HazardAlthough there is no direct link established between bis(4-hydroxyphenyl) sulfone(BPS) and cardiac disease, it is thought that bis(4-hydroxyphenyl) sulfone may operate by a similar mechanism to BPA and could cause cardiac toxicity.
Flammability and ExplosibilityNonflammable
