Diphenyl sulfone is an organosulfur compound with the formula (C₆H₅)₂SO₂. It is a white solid that is soluble in organic solvents. It is used as a high temperature solvent. Such high temperature solvents are useful for processing highly rigid polymers, such as PEEK, which only dissolve in very hot solvents.^[1]

Diphenyl sulfone is produced by the sulfonation of benzene with sulfuric acid and oleum. For typical processes, benzenesulfonic acid is an intermediate.^[2] It is also produced from benzenesulfonyl chloride and benzene.^[3]
