Nitric Acid → 1-Nitroanthraquinone

Participants

Reaction Steps

20 g of anthraquinone are introduced into 100 ml of 98 % HNO3 at 0°, the temperature rising to 10° in two minutes as a result of this addition. The reaction mixture is then nitrated at 10° for 20 minutes, with cooling by iced water. 100 ml of sulpholan are added, the temperature rising to 50° as a result. The reaction mixture is suction-filtered at 20° and the precipitate is washed with 50 ml of sulpholan and then with water, and dried. 12.7 g of 1-nitro-anthraquinone, formed by analysis to have the following composition, are obtained:
