Use | used in the manufacture of dyes The product is reduced to 1, 5-diaminoanthraquinone, used as an intermediate for Anthraquinone dyes. |
production method | is obtained by nitration of anthraquinone. The anthraquinone, nitric acid and fuming sulfuric acid were stirred together at a temperature of about 30 °c, and the temperature was adjusted to 78 °c when the end of the reaction was reached. The reactant is cooled, diluted, filtered, and refined with sodium sulfite to obtain a finished product. Industrial use of 1, 5-dinitroanthraquinone intermediates for the yellow wet product, dry content of not less than 92%. Raw material consumption quota: anthraquinone 965kg/t, nitric acid 4800kg/t, fuming sulfuric acid (20% SO3)2400kg/t. |
