HCID 6780Anthraquinone

Procedure

1-Amino-4-(3'-amino-2',4',6'-trimethyl-5'-sulfophenylthio)anthraquinone-2-sulfonic acid (23.7 parts) and cyanuric chloride (9.3 parts) were subjected a to condensation reaction at 10° to 20° C. in an aqueous medium under a weak acid condition, followed by a condensation reaction with 1-aminobenzene-3-β-sulfatoethylsulfone (14.1 parts) at 20° to 30° C. under a weak acid condition. Thereafter, salting out of the reaction mixture gave an anthraquinone compound of the following formula (free acid form). ##STR426##
