Chemical Properties |
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. |
|
Uses |
BPS is commonly used as a reactant in epoxy reactions and is also used as a latent thermal catalyst for epoxy resin. |
|
Definition |
BPS is a sulfone that is diphenyl sulfone in which both of the para hydrogens have been replaced by hydroxy groups. |
|
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. |
