| 1-Amino anthraquinone Usage And Synthesis |
| Synthesis | Anthraquinone is sulfonated with nicotinic sulfuric acid in the presence of a small amount of mercury salt to generate anthraquinone-1-sulfonic acid, which is then neutralized with potassium hydroxide to form anthraquinone sulfonic acid potassium salt. Under high temperature and high pressure, ammonia and anthraquinone sulfonic acid potassium The salt action generates 1-aminoanthraquinone, and the generated sulfite reacts with the product again and the quality of the product decreases. Therefore, nitrobenzene sulfonate is usually used as an oxidant to oxidize sulfite to sulfate, which itself is reduced to m-aminobenzenesulfonic acid. | | Description | Anthraquinone dyes are the second largest class of dyes after azo dyes, and 1-aminoanthraquinone is an important intermediate for the synthesis of anthraquinone dyes. It is the main raw materials of amino acid and pyrazole anthraquinone occupy an extremely important position in the dye industry. | | Chemical Properties | deep brown crystalline powder | | Uses | 1-Aminoanthraquinone is the most important intermediate for manufacturing acid, reactive, disperse, and vat dyes. | | Uses | In the manufacturing of dyes and pharmaceuticals | | Biochem/physiol Actions | 1-Aminoanthraquinone has the ability to increase the solubility of derivatives of anthraquinone in supercritical carbon dioxide. | | Safety Profile | Moderately toxic by intraperitoneal route. An eye irritant. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic NO,. See also AMINES |
