HCID 67041-Nitroanthraquinone

Procedure

Anthraquinone is nitrated using a mixed acid comprising sulfuric acid and nitric acid, the concentration of sulfuric acid being 70 to 76% by weight and the amount of nitric acid being 33 to 55% by weight based on the total weight of sulfuric acid and nitric acid, whereby 1-nitroanthraquinone is obtained in a high yield and a high purity.
