Packaged in iron drums lined with plastic bags. Net weight per barrel is 25kg or 50kg. Store in a cool, ventilated place. Moisture-proof and sun-proof. Store and transport according to regulations on toxic chemicals.

Synthesis method

1. Nitrification reduction method: Anthraquinone is nitrated with mixed acid to obtain nitroanthraquinone. The reaction product is filtered and washed with hot water until neutral, and then refined with sodium sulfite. Among them, 2-nitroanthraquinone and sodium sulfite generate anthraquinone-2-sodium sulfonate that is easily soluble in water, which is removed by filtering and washing. The obtained 1-nitroanthraquinone is reduced with sodium sulfide to obtain crude 1-aminoanthraquinone, which is refined by adding alkali solution and insurance powder to remove the diaminoanthraquinone, and then oxidized with oxygen, filtered, and dried to obtain the finished product.

2. Anthraquinone sulfonate ammonolysis method: Anthraquinone reacts with fuming sulfuric acid in the presence of mercury sulfate to generate anthraquinone-1-sulfonic acid, which is neutralized with ammonia and then replaced with sodium salt, and then catalyzed by sodium m-nitrobenzene sulfonate Under ammonolysis, 1-aminoanthraquinone is generated, and the finished product is obtained after refining.


Purpose

1. Determine nitrite. Dyes and pharmaceutical intermediates. Organic Synthesis. 2. Important dye intermediates. It can be used to produce reduced khaki 2G, reduced red brown R, reduced olive green B, olive T, olive R, reduced gray M, dispersed red 3B, as well as reactive brilliant blue KN-R and reactive brilliant blue M-BR. ?
