Versuchsvorschrift

The wet filter cake of 1-nitro-2-methylanthraquinone (0.45 mole) was placed in a 5 l flask. To the flask was added 420 g (1.75 mole) of Na2S.9H2O dissolved in 2.5 l of H2O and the slurry was heated and then stirred at 95°-99° C. for 2 hours. The reaction mixture was filtered and the orangish-red solid 1-amino-2-methylanthraquinone product was washed with hot H2O until the filtrate was clear and dried in vacuo at 70° C.
