Product 1

HCID 6780Anthraquinone

Procedure

1-Amino-2-(3'-amino-4'-sulfophenoxy)-4-(4'-sulfophenylthio)anthraquinone (6 parts) and cyanuric chloride (1.8 parts) were subjected a to condensation reaction at 5° to 30° C. under a weak acid condition in an aqueous medium, and then salting out of the reaction mixture gave an anthraquinone compound of the following formula (free acid form). ##STR166##
