30 g of tricyclohexylbenzene was dissolved in 50 ml of methylene chloride, followed by cooling/stirring at 3° C., and 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 further charged with 40 g of an aqueous 50% sodium hydroxide solution. Furthermore, 20 g of ethanol was added, followed by stirring at 50° C. for 1 hour, and after removing insoluble matters by filtration, the filtrate was distilled off under reduced pressure at 40° C. The precipitated crystal was collected by filtration and subjected to hexane washing to obtain 30 g of sodium 1,3,5-tricyclohexylbenzenesulfonate.
