What is the production method of 1-Amino-2-Hydroxylnaphthalene-4-Sulfonic Acid?

1-Amino-2-hydroxynaphthalene-4-sulfonic acid, the method of preparation in the past is roughly as follows:
Initially, 2-naphthol is used as the starting material and is sulfonated. Mix 2-naphthol with sulfuric acid to control the temperature, duration and other conditions. At a suitable temperature, sulfuric acid reacts with 2-naphthol, and the sulfonic acid group gradually enters the molecular structure of naphthol to obtain an intermediate product containing a sulfonic acid group.
After that, the step of nitrification is carried out. Meet the above intermediate product with the mixed acid of nitric acid and sulfuric acid, and carefully adjust the reaction situation. With the help of sulfuric acid, nitro groups are introduced into the naphthalene ring of the intermediate product to obtain a new compound containing sulfonic acid groups and nitro groups.
Then, the reduction method is carried out. A system composed of metal (such as iron, etc.) and acid (such as hydrochloric acid), or a catalytic hydrogenation technique is used to convert the nitro group into an amino group, and then the 1-amino-2-hydroxynaphthalene-4-sulfonic acid precursor is obtained.
At the end, it is separated and purified through various processes. Using crystallization, filtration, washing and other means, the pure 1-amino-2-hydroxynaphthalene-4-sulfonic acid was extracted from the reaction mixture to meet the purity standards required by industry or experiments.
