실험 절차
22.6 of 1,2,2,5,5-pentamethylcyclohexanol are dissolved in 280 ml of benzene and, after the addition of 100 mg of p-toluenesulphonic acid, the mixture is boiled on a water separator for 7 hours. After cooling the solution, some solid sodium carbonate is added thereto, the mixture is filtered and the filtrate is evaporated at normal pressure. The residue is distilled in a water-jet vacuum. There are obtained 15.8 g of 1,3,3,6,6-pentamethylcyclohexen as a colorless liquid, b.p. 56°-57° C./17 mm.
