실험 절차

4.0 g of sodium 4,8-diamino-1,5-dihydroxy-anthraquinone-2,6-disulfonate is dissolved in a mixture of 2.0 g of boric acid and 30 ml concentrated sulphuric acid heated to 80° C. The blue solution obtained is cooled to a temperature of 0° to 5° C., and 2.8 g of butoxybenzene is stirred in drop by drop, the colour then changing from blue to reddish brown. The mixture is agitated for a further two hours at 0° to 10° C., then poured onto ice. The suspension obtained is heated on reflux for 4 hours to destroy the boric ester, and a violet precipitate is filtered off after cooling, corresponding to 4,8-diamino-1,5-dihydroxy-3-p-butoxyphenyl-anthraquinone-6-sulphonic acid. The moist precipitate is dissolved hot in a mixture of 24 ml of 33% ammonia and 160 ml of water, and the sulphonic groups are separated by adding 2.2 g of sodium dithionate in stages. The mixture is finally heated to 95° C. for approximately 2 hours, then cooled and filtered. The precipitate thus obtained is washed with slightly acidified water, then with a great excess of water, and dried. The desired product may further be purified by crystallisation or chromatography if necessary.
