6.83 g of aluminum chloride was added to 20.0 g of benzene, and the mixture was stirred under cooling at 3° C. Subsequently, 40.4 g of cyclohexyl chloride was slowly added dropwise and after the dropwise addition, the reaction solution was stirred at room temperature for 5 hours and then poured in ice water. The organic layer was extracted with ethyl acetate, and the obtained organic layer was distilled off under reduced pressure at 40° C., further distilled off under reduced pressure at 170° C., then cooled to room temperature and recrystallized by charging 50 ml of acetone thereinto. The precipitated crystals were collected by filtration to obtain 14 g of tricyclohexylbenzene.
