Bisphenol S, chemical name 44'- dihydroxydiphenylsulfone, English name 44 sulfonyldiphenol, 4,4'-Dihydroxydiphenylsulfone bisphenol S, etc., referred to as 44-bps, or bps. The molecular formula is C12H10O4S, the relative molecular weight is 250.27, and the CAS number is 80-09-1. High purity BPS is white acicular or powdery crystal, melting point 245-250 ℃, low toxicity. The solubility characteristics of BPS are as follows: it is easily soluble in ether, alcohol, acetone and aliphatic hydrocarbons, slightly soluble in hot water, and difficult to dissolve in cold water. The water solubility is 1.1g/l (20 ℃). From the structural formula in Figure 1-1, it can be seen that the benzene ring of BPS is connected with two hydroxyl groups, and there is a sulfonyl group with strong electric absorption capacity. Therefore, compared with other phenolic substances, BPS is more acidic: the conjugated system of BPS is enhanced.
The stability of the molecule is improved, so that it has good performance in heat resistance, light resistance and oxidation resistance.
Bisphenol s has a wide range of uses. It can be used as raw materials or Intermediates to produce pesticides, dyes, etc., especially in polymers, which can replace bisphenol A, which may affect the human endocrine system, and is superior to bisphenol A in performance and safety. It can also be used as dispersant of dyes for high temperature dyeing, additive of electroplating solution and flame retardant. It is also used in the manufacture of color photographic materials, chromogenic agents, surfactants and deodorants.
