When phenol and sulfuric acid are reacted to produce 4,4'-bisphenol sulfone, the dehydration reaction is carried out in a mixed solvent composed of aliphatic saturated hydrocarbons with a boiling point of 175°C or higher and mesitylene, and finally Distilling mesitylene from the reaction system, or reacting it in a solvent containing aliphatic saturated hydrocarbon in a reaction vessel equipped with a rectification device, it is excellent in operability and can be produced in high yield 4, 4'-bisphenol sulfone. In addition, after reacting in a solvent containing an aliphatic saturated hydrocarbon, an alcohol having 1 to 3 carbon atoms is added to the reaction liquid, and 4,4'-bisphenol sulfone is recrystallized from the alcohol layer after liquid separation. This enables easy and high-purity 4,4'-bisphenol sulfone to be obtained.
