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.
