Chemische Eigenschaften
White 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.
Verwenden
Bis(4-hydroxyphenyl) Sulfone is commonly used as a reactant in epoxy reactions and is also used as a latent thermal catalyst for epoxy resin.

Definition
4,4'-Sulfonyldiphenol is a sulfone that is diphenyl sulfone in which both of the para hydrogens have been replaced by hydroxy groups.
synthetische
A 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.
Allgemeine Beschreibung
Bisphenol 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 Hazard
Although 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 Explosibility
Non flammable
