1-amino anthraquinone sulfonation process for bromamine acid production

The invention relates to the technical field of organic synthesis, and discloses a 1-amino anthraquinone sulfonation process for bromamine acid production, which has the advantages of mild reaction conditions, no pollution, meeting of the concept of green chemistry, simplicity and convenience in operation, and high-efficiency synthesis of a precursor 1-amino anthraquinone-2-sulfonic acid product of bromamine acid by regulating and controlling a recrystallized benign solvent and a poor solvent. The purity is high and the yield is high.

Process for synthesizing 1-amino-anthraquinone-2-sulfonic acid through solid-phase method

The invention provides a method for synthesizing 1-amino-anthraquinone-2-sulfonic acid from 1-amino-anthraquinone. The method comprises the following steps: generating a sulfate solid of 1-amino-anthraquinone through reaction of the 1-amino-anthraquinone and sulfuric acid, and then performing transposition on the sulfate solid of the 1-amino-anthraquinone to generate the 1-amino-anthraquinone-2-sulfonic acid. A process of synthesizing the 1-amino-anthraquinone-2-sulfonic acid by a sulfuric acid method is fundamentally improved; the sulfate of the 1-amino-anthraquinone is efficiently subjectedto transposition reaction under a solid-phase condition without a solvent after generated water is removed, so that the reaction yield is high, and no side effects are caused; furthermore, no 1-amino-4-chloroant-2-sulfonic acid is generated, and no wastewater, waste gas and waste residues are generated; an obtained product is further synthesized into bromamine acid, and the purity of the obtainedbromamine acid is close to 100 percent; the quality and the yield of the bromamine acid are both higher than the quality and the yield of bromamine acid synthesized by a chlorosulfonic acid method, afuming sulfuric acid method and a conventional sulfuric acid method.
