During reaction of phenol and sulfuric acid to produce 4, 4í»-bisphenol sulfone, the reaction system is dewatered in mixed solvent comprising saturated aliphatic hydrocarbon of boiling point not lower than 175 deg.c and mesitylene, and the reaction system is ultimately distilled to eliminate mesitylene. Or, the reaction is completed in solvent containing saturated aliphatic hydrocarbon inside a reaction container with rectifier, so as to obtain excellent operation performance and high yield of 4, 4í»-bisphenol sulfone. In addition, after reaction in solvent containing saturated aliphatic hydrocarbon, C1-C3 alcohol is added into the reacted solution, so that 4, 4í»-bisphenol sulfone is re-crystallized in separated alcohol layer and high purity 4, 4í»-bisphenol sulfone product is obtained simply.
