4,4'-Dichlorodiphenyl sulfone
4,4′-Dichlorodiphenyl sulfone is an organic compound with the formula 2SO2. Classified as a sulfone, this white solid is most commonly used as a precursor to polymers that are rigid and temperature-resistant such as PES or Udel.DCDPS is synthesized via sulfonation of chlorobenzene with sulfuric acid, often in the presence of various additives to optimize the formation of the 4,4′-isomer:
It can also be produced by chlorination of diphenylsulfone.
With chloride substituents activated toward substitution, DCDPS is useful in the production of polysulfones:
