Reaction Conditions

Reaction Steps

Tricyclohexylbenzene (30 g) was dissolved in 50 ml of methylene chloride, followed by stirring under cooling at 3° C., and 15.2 g of chlorosulfonic acid was slowly added dropwise thereto. After the dropwise addition, the resultant was stirred at room temperature for 5 hours, and 10 g of ice was added thereto. Subsequently, 40 g of 50% aqueous sodium hydroxide solution was added thereto, and 20 g of ethanol was further added thereto. The resultant was stirred at 50° C. for an hour, the insoluble fraction was then removed by filtering, and the resultant was removed by distillation under reduced pressure at 40° C. The precipitated crystals were collected through filtering and washed with hexane, thereby obtaining 30 g of sodium 1,3,5-tricyclohexylbenzene sulfonate.
