실험 절차

16.5 parts of a mixture of 1,5-dinitro-4,8-dihydroxyanthraquinone and 1,8-dinitro-4,5-dihydroxyanthraquinone (about 1:1 parts) is heated with 50 parts of phenol for eight hours at 180° C while stirring. After cooling 100 parts by volume of methanol is added, the precipitate is suction filtered and the residue is washed with methanol and then with hot water. After drying 13 parts of a mixture of 1-amino-5-nitro-4,8-dihydroxyanthraquinone and 1-amino-8-nitro-4,5-dihydroxyanthraquinone is obtained; this is equivalent to 87% of the calculated yield.
