| Hazard Information | Back Directory | [Chemical Properties]
4,4'-Sulfonyldiphenol is light yellow crystalline powder
| [Uses]
4,4'-Sulfonyldiphenol 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4,4'-Sulfonyldiphenol is a sulfone that is diphenyl sulfone in which both of the para hydrogens have been replaced by hydroxy groups.
| [Preparation]
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. | [General Description]
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]
Nonflammable |
