Reaction Steps
Add 1,8-dinitroanthraquinone (1.49 g, 5 mmol) into 56 ml ethanol and stir the mixture. Then add a reductive solution containing sodium sulfide nonahydrate (5.4 g, 22.5 mmol), sodium hydroxide (2.14 g, 53.5 mmol) dissolved in 95 ml water. The mixed solution is reflux heated for 6 hours, standing overnight, and filter the precipitate. The precipitate is recrystallized from ethanol to get red compound 2.
