Abstract
A diphenylsulfone compound containing 4,4′-dihydroxydiphenylsulfone is produced in good yield in a short time and at a relatively low temperature. A diphenylsulfone compound represented by formula (2) below is produced by irradiating, with microwaves, a compound represented by formula (1) below and a sulfonating agent so that a dehydration condensation reaction is carried out.
