실험 절차

A mixture of 36.8 g. (0.20 mole) of cyanuric chloride, 88.0 g. (0.66 mole) of anhydrous aluminum chloride and 250 ml. of o-xylene was heated at 45°C for 1.5 hours. After cooling to room temperature, the mixture was poured into ice water, and then steam distilled to remove the excess o-xylene. The water was decanted from the pot residue and the remaining solid filtered, washed with acetone and dried to yield 58.1 g. of product, m.p. 220°-230°. Recrystallization from benzene gave an analytically pure sample, m.p. 235°-236°.
