反应详情

A 10g amount of benzanthrone was dissolved in a solvent mixture of 100g acetic acid and 100 g of water. 6 g of potassium chlorate was added to the solution and the mixture was heated and stirred at 90°-95° C for 2 hours. 12 g of conc. hydrochloric acid was added dropwise to the mixture during 1 hour and 20 minutes. After the addition, the mixture was stirred for 1 hour to complete the reaction. The reaction mixture was cooled, filtered, washed with water and dried. The product was recrystallized from chlorobenzene to obtain 3-chlorobenzanthrone having a melting point of 179°-190° C (orange needle crystals).
