What is Diphenyl Sulfone?
White flake crystal. The melting point is 128-129 ℃, the boiling point is 379 ℃, 232 ℃ (2.4kPa), and the relative density is 1.252 (20/4 ℃). Soluble in hot ethanol, ether and benzene, slightly soluble in hot water, insoluble in cold water.
Diphenylsulfone is a sulfone compound with two S-phenyl substituents. It is a crystalline powder soluble in organic solvents. It has been found in Gni dia glauca, Dioscorea bulbifera and other plants. It has the function as plant metabolite.
Under certain conditions, the sulfuric acid solution reacts with benzene to form diphenyl sulfone. Used as high-temperature solvent. This high-temperature solvent can be used to process highly rigid polymers, such as PEEK, which are only soluble in very hot solvents. It is prepared by sulfonation of benzene with sulfuric acid and oleum. For a typical process, benzenesulfonic acid is an intermediate. It is also produced from benzene sulfonyl chloride and benzene.
Diphenyl Sulfone Uses
- Phenylsulfone is deoxidized with Mg MeOH at room temperature.
- Diphenyl sulfone is used in organic synthesis as plasticizer and acaricide.
- Diphenyl sulfone is used as intermediate of medicine and pesticide.
- Diphenylsulfone was determined to be the preferred solvent. Compared with dimethyl sulfoxide, diphenyl sulfone is chemically and thermally stable.
