반응 단계
363 g (1.37 moles) of 1-acetamino-anthraquinone are stirred into 3.5 kg of ethanol, 150 ml of concentrated sodium hydroxide solution (d = 1.48) are added and the mixture is then heated to the reflux temperature (80° C) for three hours. After cooling to 15° C, the red suspension is suction filtered. The residue is washed on the suction filter with hot water until the filtrate has a neutral reaction. After drying, 291 g of 1-amino-anthraquinone are obtained (yield: 95.2%). Degree of purity: 98 to 99%.
