실험 절차

10 parts of 1-nitroanthraquinone-2-carboxylic acid and 2 parts of hydroxylammonium sulfate are suspended at room temperature in 60 parts of isopropanol and 100 parts of 4 N sodium hydroxide. The mixture is refluxed for 3 hours, then cooled to room temperature, diluted with water and acidified with hydrochloric acid. The mixture is filtered and the filter cake is washed netural with water and dried, affording 7 parts of 1,4-diaminoanthraquinone-2-carboxylic acid.
