实验过程

Aluminum chloride (6.38 g) was added to 20.0 g of benzene, followed by stirring under cooling at 3° C., and 40.4 g of cyclohexyl chloride was slowly added dropwise thereto. After the dropwise addition, the resultant was stirred at room temperature for 5 hours, and the obtained reaction solution was added to ice water. The organic layer was extracted by using ethyl acetate, and the obtained organic layer was removed by distillation at 40° C. under reduced pressure. The resultant was further removed by distillation at 170° C. under reduced pressure and then cooled to room temperature, and 50 ml of acetone was added thereto to cause recrystallization. The precipitated crystals were collected through filtering, thereby obtaining 14 g of tricyclohexylbenzene.
