Versuchsvorschrift

363 g (1.37 moles) of 1-acetamino-anthraquinone are warmed with 3.5 kg of methanol and 150 ml of concentrated sodium hydroxide solution (d = 1.48) in a stainless steel autoclave for 3 hours at 85° C. After cooling to room temperature, the red suspension is suction filtered. The residue on the suction filter is washed with hot water until the filtrate has a neutral reaction. After drying, 290 g of 1-amino-anthraquinone are obtained (yield: 95%). Degree of purity: 98 to 99%.
