実験手順

First of all, 17.3 g (0.1 mol) of 3-aminobenzenephosphonic acid was dispersed in a solution of 70 ml of water and 8 g of sodium hydroxide and mixed throughout. To the mixture, 8 g of sodim bicarbonate and 16 g (0.04 mol) of 1-amino-4-bromoanthraquinone were added and 0.6 g of copper chloride was then added and mixed at 70° to 75° C. until the reaction was terminated. The resultant mixture was filtered and the filtrate was made acidic to remove excess 3-aminobenzenephophonic acid. Sodium chloride was added to the filtrate and salted out, filtered and dried. It was then purified with alcohol to obtain a blue anthraquinone compound (20 g).
