Procedure
The semi-solid oily 4,4'-thiobis(6-cyclohexyl-3-methylphenol) is dissolved in acetic acid (100 ml), to which 35% hydrogen peroxide (9.7 g) is added at 40° C. over a period of 2 hours. Further, 35% hydrogen peroxide (20 g) is added thereto at 50°-60° C. over a period of 6 hours. After the reaction, water is added thereto and the water layer is decanted off. Dichloroethane is added to the resulting oily substance to allow precipitation. The crystals are filtered off and recrystallized from ethanol to give 4,4'-sulfonylbis(6-cyclohexyl-3-methylphenol), m.p. 301° C. (decomposition).
