Vorschrift

To 20.0 g of benzene, 6.83 g of aluminum chloride was added, cooled by 3° C. and stirred, and 40.4 g of cyclohexyl chloride was slowly added dropwise. After the dropwise addition, the mixture was stirred for 5 hours at room temperature and was poured into ice water. An organic phase was extracted using ethyl acetate and the obtained organic phase was distilled off at reduced pressure at 40° C. After further distilling off at reduced pressure at 170° C., the organic phase was cooled to room temperature, 50 ml of acetone was introduced and recrystallized. The precipitated crystals were filtered off and 14 g of tricyclohexylbenzene was obtained.
