Tricyclohexylbenzene (30 g) was dissolved in 50 ml of methylene chloride, and the resulting solution was cooled with stirring at 3° C. Thereto, 15.2 g of chlorosulfonic acid was gradually added dropwise. After the dropwise addition, the reaction solution was stirred at room temperature for 5 hours, and 10 g of ice was poured thereinto. Furthermore, 40 g of an aqueous 50 mass % sodium hydroxide solution was poured therein, and 20 g of ethanol was then added. This mixture was stirred at 50° C. for 1 hour, and insoluble matters were removed by filtration. The residue was distilled off under reduced pressure at 40° C., and the precipitated crystal was collected by filtration and washed with hexane to obtain 30 g of sodium 1,3,5-tricyclohexylbenzenesulfonate.
