Anthraquinone is nitrated with a mixed acid prepared with sulfuric acid and nitric acid, and then sulfonated with sodium sulfite to produce sodium sulquinone-1-sulfonate. In the boiling state Dropwise into the hydrochloric acid solution of sodium chlorate for chlorination, filtration, drying to obtain the finished product.
used as an intermediate for anthraquinone vat dyes and other Anthraquinone dyes, such as reduced Brown BR dyes.
