2,5-Bis (4-amino-3-sulphophenylamino)-3,6-dichlorobenzoquinone was obtained via the condensation between 1,4-diaminobenzene-2-sulphonic acid and tetrachloro-p-benzoquinone. The condensation product then underwent an intramolecular cyclization in the presence of 15%oleum and ammonium peroxodisulfate to afford 3,10-diamino-6,13-dichlorotriphendioxazine-4,11-disulphonic acid, which reacted with benzenesulfinic acid sodium in the presence of benzoyl peroxide to afford triphendioxazine acid blue AXG. The material ratios, reaction temperature, and reaction time of both the condensations and the cyclization were discussed, and an optimized reaction condition was established.
