PROBLEM TO BE SOLVED: To provide an industrially useful production method of 1,4-bis(1,1,1,3,3,3-hexafluoro-2-hydroxyisopropyl)phenol. SOLUTION: The production method for 1,4-bis(1,1,1,3,3,3-hexafluoro-2-hydroxyisopropyl)phenol comprises the following two steps: (1) 1,4-bis(1,1,1,3,3,3-hexafluoro-2-hydroxyisopropyl)benzene as the raw material is reacted with a bromizing agent in the presence of sulfuric acid in a solvent to produce 1,4-bis(1,1,1,3,3,3-hexafluoro-2-hydroxyisopropyl)bromobenzene; and (2) this bromobenzene is hydrolyzed by heating in an aqueous alkaline metal solution in the presence of a catalyst to produce 1,4-bis(1,1,1,3,3,3-hexafluoro-2-hydroxyisopropyl)phenol.
