실험 절차
Cyclohexyl benzene (500 gm, 3.12M) is stirred in a five liter 3-necked flask equipped with a condenser and a thermowatch, and is warmed to 70° C. Sulfuric acid (381 gm, 3.74M) and 30% oleum (38.2 gm) are added dropwise to the stirred reaction at a rate sufficient to maintain a temperature of approximately 70°-75° C. When the addition is complete, the reaction is aged at 70° C. for three hours and then cooled. The resulting reaction mixture, which is deep red in color, then is drowned in two liters of a saturated NaCl solution that is cooled to approximately 5° C. The solid precipitated in the salt solution then is filtered and washed with hexane, following which the precipitate is dried in a vacuum oven at 75° C.
