실험 절차

In a 250 ml three-necked round-bottom flask equipped with a reflux condenser, thermometer, dropping funnel with pressure-equalizing, and magnetic stirring bar, and containing 74.9 g (0.30 mol) of 3,6-dibromotoluene, 15.5 ml (47.9 g, 0.30 mmol) of bromine was added dropwise under exposure to 500 W lamp for 3 hours at 190° C. The resulting mixture was cooled to room temperature. Fractional distillation gave colorless liquid, b.p. 132-135° C./3 mm Hg. Yield 84.3 g (85%).
