Versuchsvorschrift

363 g (1.37 moles) of 1-acetamino-anthraquinone are warmed with 3.5 l of water and 130 ml of concentrated sodium hydroxide solution (d = 1.48) in a stainless steel autoclave for 5 hours at 150° C. After cooling to room temperature, the red suspension is filtered. The residue is washed with hot water until neutral. After drying, 300 g of 1-amino-anthraquinone are obtained (yield: 98%). Degree of purity: 97 to 98%.
