実験手順

Aluminum chloride (6.83 g) was added to 20.0 g of benzene, and the mixture was stirred under cooling at 3° C. Thereto, 40.4 g of cyclohexyl chloride was slowly added dropwise. After the dropwise addition, the mixture 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 at 40° C. under reduced pressure, further distilled at 170° C. under reduced pressure, then cooled to room temperature, and recrystallized by charging 50 ml of acetone. The precipitated crystal was collected by filtration to obtain 14 g of tricyclohexylbenzene.
