Reaction Steps

20 Parts of acrylic acid are gradually added to a mixture of 15.8 parts of 1,4-diamino-2,3-dichloroanthraquinone, 3.1 parts of boric acid and 100 parts of 100% sulphuric acid at 25°-30° C, and the mixture is then stirred for 60 hours at 25°-30°. The reaction mixture is then processed as described in Example 1 to give 21 parts (93%) of 1,4-bis(β-carboxyethylamino)-2,3-dichloroanthraquinone.
