実験手順

8.25 parts of 1,8-dihydroxy-4,5-dinitroanthraquinone is heated in 40 parts of phenol in the presence of 1 part of morpholine for 3 hours at 140° to 150° C. Then another 1 part of morpholine is added and the whole is heated for 1 hour at 150° C. The reaction mixture is allowed to cool to 60° C, 80 parts of methanol is added and the precipitated reaction product is suction filtered. The filter residue is washed with hot water and dried. 4.9 parts of 1-amino-8-nitro-4,5-dihydroxyanthraquinone is obtained.
