실험 절차

122 Grams of 5-nitro-1,4-naphthoquinone which contained 10% of the 6-nitro compound, 2,800 grams of methyl cellosolve and 48 grams of 1,3-butadiene were placed in an autoclave, followed by reaction at 90° C. for 2 hours. After allowing to cool, 1.2 grams of a 5% palladium on carbon catalyst and 120 grams of a 20% aqueous sodium hydroxide solution were added to the reaction solution. Then, the procedure of Example 13 was repeated to obtain 108 grams of 1-aminoanthraquinone containing 7% of 2-aminoanthraquinone.
