반응 단계

Tricyclohexylbenzene amounting to 30 g was dissolved in 50 ml of methylene chloride and agitated while cooling at 3° C. Then, 15.2 g of chlorosulfonic acid was slowly dropped into the solution. After the completion of the dropping, the mixture was agitated at room temperature for five hours. Subsequently, 10 g of ice and then 40 g of 50% aqueous sodium hydroxide solution was poured into the mixture. Further, 20 g of ethanol was added and agitated at 50° C. for an hour. Any insoluble matter was removed by filtration, and the product was subjected to vacuum distillation at 40° C. The thus obtained crystal was collected by filtration, and washed with hexane, thereby obtaining 30 g of sodium 1,3,5-tricyclohexylbenzenesulfonate.
