4,4′-Dichlorodiphenyl sulfone (DCDPS) is an organic compound with the formula (ClC6H4)2SO2. Classified as a sulfone, [1] this white solid is most commonly used as a precursor to polymers that are rigid and temperature-resistant such as PES or Udel. [2]
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. [3]
With chloride substituents activated toward substitution, DCDPS is useful in the production of polysulfones:
