Properties and stability

Poisonous. The raw material anthraquinone can cause allergic eczema, rhinitis, and bronchial asthma. The reaction equipment should be sealed and the workshop should be well ventilated.

Storage method

Stored sealed and protected from light. Packed in iron drums lined with plastic bags, net weight per drum is 50~100kg. Should be stored in a dry, ventilated place, protected from sun and moisture. Store and transport according to general toxic chemicals regulations.

Synthesis method

Anthraquinone is nitrated with a mixed acid of sulfuric acid and nitric acid, and then sulfonated with sodium sulfite to generate sodium anthraquinone-1-sulfonate. The hydrochloric acid solution of sodium chlorate is dropped into the boiling state for chlorination, filtered, and dried to obtain the finished product.


Used as an intermediate for anthraquinone vat dyes and other anthraquinone dyes, such as vat brown BR dye.
