실험 절차

A mixture of 1,5-dichloroanthraquinone (13.8 grams, 0.05 mole), o-mercapto benzoic acid (15.4 grams, 0.10 mole), potassium carbonate (13.8 grams, 0.10 mole), and N,N-dimethylformamide (200 ml) was heated at approximately 125° C. for four hours. The reaction mixture was allowed to cool to room temperature and then drowned into water (500 ml) and acidified with acetic acid to a pH of about 5.0. The dye was collected by filtration, washed with hot water, and then dried in air to yield 23.5 grams of 1,5-bis(2-carboxyphenylthio)anthraquinone.
