3-Amino-8-Naphthol-4, what is the production method of 6-Disulfonic Acid

The production method of 3-amino-8-naphthol-4,6-disulfonic acid has been known since ancient times. At the beginning of the method, naphthalene is mostly used as the starting material, and it is formed by sulfonation, nitrification, reduction, etc.
The first step is sulfonation. Naphthalene is mixed with sulfuric acid, heated to an appropriate temperature, and a sulfonic acid group is introduced into the naphthalene ring to obtain a mixture of naphthalene sulfonic acid. This step requires careful control of the temperature and the concentration of sulfuric acid. If the temperature is too high, too many sulfonic acid groups are introduced, which is unfavorable for subsequent reactions; if the temperature is too low, the reaction is slow and the yield is also low. After nitration, a mixture of nitric acid and sulfuric acid is added to the naphthalene sulfonic acid system to introduce nitro groups at specific positions on the naphthalene ring. The reaction is intense, and strict cooling is required to control the reaction rate and prevent side reactions from clumping and causing impure products.
Then the reduction is carried out. Nitro-naphthalene sulfonic acid is used as the substrate, and the nitro group is converted into an amino group by reducing agents such as iron powder and sodium sulfide. This reduction method has its own advantages and disadvantages. Although the cost of iron powder reduction is low, the product separation is complicated; the reduction of sodium sulfide is relatively mild, but it has a certain impact on the environment.
After separation and refining, impurities are removed to obtain pure 3-amino-8-naphthol-4,6-disulfonic acid. Separation methods are often used for crystallization, extraction, etc. In refining, recrystallization, ion exchange, etc. are used to increase the purity of the product.
In today's production, new technologies have also emerged, such as catalytic synthesis methods, which can improve reaction efficiency, reduce energy consumption, and reduce environmental pollution. However, the ancient method is still used in some occasions because of its simple equipment and familiar operation.
