4,4′-Dichlorodiphenyl sulfone CAS:80-07-9

4,4′-Dichlorodiphenyl sulfone CAS:80-07-9 Product introduction

Product name: Bis(4-hydroxyphenyl) Sulfone

CAS: 80-09-1

MF:C12H10O4S

MW:250.2704

Appearance: white crystal

4,4′-Dichlorodiphenyl sulfoneChemical Properties:

White needle crystals. Bulk density 0.5 ~ 0.6g/cm3. Melting point 240-241 ℃. Soluble in aliphatic hydrocarbons, soluble in ethanol, isopropanol, 2-ethylhexanol, acetonitrile, acetone, slightly soluble in aromatic hydrocarbons, slightly soluble in ethyl acetate, methyl isobutyl ketone, insoluble in toluene and water.

The molecule contains two hydroxyl groups and a strong electron-withdrawing sulfone group, so the acidity is stronger than other phenols. Low toxicity.

4,4′-Dichlorodiphenyl sulfone CAS:80-07-9 COA:

4,4′-Dichlorodiphenyl sulfone CAS:80-07-9 Application:

1.4,4′-Dihydroxydiphenylsulfone is mainly used as a color-fixing agent.

2.It can be used as plating solution additive, leather tanning agent, dispersant for high temperature dyeing of disperse dyes, phenolic resin hardening accelerator, resin flame retardant, etc.

3.It is also an intermediate for pesticides, dyes and auxiliaries.

4.As a substitute for bisphenol A, it can be used as the raw material of polycarbonate, epoxy resin, polyester, phenolic resin, and raw material of polysulfone and polyethersulfone.

5.The product is also used in the manufacture of color photographic materials, photographic contrast enhancers, heat-sensitive recording materials (color developers), daily surfactants and high-efficiency deodorants.

6.Using bisphenol S as raw material, color-fixing agent A (foreign trade name is CibatexPA) can be prepared.
