Procedure

Subsequently, 30 g of tricyclohexylbenzene was dissolved in 50 ml of methylene chloride, and the solution was stirred under cooling at 3° C. Thereto, 15.2 g of chlorosulfonic acid was slowly added dropwise. After the dropwise addition, the mixture was stirred at room temperature for 5 hours, charged with 10 g of ice and then charged with 40 g of an aqueous 50% sodium hydroxide solution. furthermore, 20 g of ethanol was added, and the mixture was stirred at 50° C. for 1 hour. Insoluble matters were removed by filtration, and the residue was distilled at 40° C. under reduced pressure. The precipitated crystal was collected by filtration and washed with hexane to obtain 30 g of sodium 1,3,5-tricyclohexylbenzenesulfonate.
