    What is the production method of Disodium 4- [ (E) - (2,4-Dimethylphenyl) Diazenyl] -3-Hydroxynaphthalene-2, 7-Disulfonate
    The method of making disodium 4- [ (E) - (2,4-dimethylphenyl) azo] -3-hydroxy naphthalene-2,7-disulfonate is obtained by multi-step transformation.
    At the beginning, take 2,4-dimethylaniline and make it react with an appropriate amount of sodium nitrite in acid solution at low temperature. Hydrochloric acid or sulfuric acid are commonly used in acid solution, and the temperature is controlled at 0 to 5 degrees Celsius. This temperature can maintain the stability of diazonium salt. After the reaction, a diazonium salt solution is obtained.
    Next, prepare a solution of sodium 3-hydroxy naphthalene-2,7-disulfonate, pour it slowly into the above diazonium salt solution, and stir at the same time to control the pH value in the weakly basic range, about 8 to 9. At this time, the diazonium salt and 3-hydroxy naphthalene-2,7-disulfonate undergo a coupling reaction to form a disodium 4- [ (E) - (2,4-dimethylphenyl) azo] -3-hydroxy naphthalene-2,7-disulfonate crude product.
    Thereafter, the crude product is subjected to a refining technique. First dissolve in a suitable solvent, such as hot water or a polar organic solvent, to filter out insoluble impurities. Then, by means of crystallization, or cooling, or adding a precipitant, the product precipitates pure crystals. The crystals are washed with solvent to remove residual impurities, and dried in vacuum to obtain a high-purity target product. The whole preparation process requires strict control of reaction conditions, such as temperature, pH value, proportion of reactants, etc., to ensure the quality and yield of the product.
