What are the methods of preparing 6-Nitro-1-Amino-2-Naphthol-4-Sulfonic Acid?

6-Nitro-1-amino-2-naphthol-4-sulfonic acid, the ancient production method is quite complicated, and it needs to be done with delicate methods and careful states.
First, naphthalene can be prepared by sulfonation, nitrification and other multi-step reactions. First, the naphthalene is placed in a suitable reactor, using sulfuric acid as a sulfonating agent, at a specific temperature and time, the naphthalene is sulfonated to obtain naphthalene sulfonic acid. This step requires attention to the concentration of sulfuric acid, the reaction temperature and time. If it is not properly controlled, the product will be impure.

Because the nitrification reaction is very violent, it is easy to cause danger if there is a little carelessness, and the temperature affects the nitro substitution position of the product. After nitrification, nitro-containing naphthalenesulfonic acid derivatives can be obtained.
Subsequently, through reduction and hydroxylation, the nitro group is reduced to amino group, and the hydroxyl group is introduced, and the final product is 6-nitro-1-amino-2-naphthol-4-sulfonic acid. Suitable reducing agents are commonly used in the reduction process, such as iron powder and hydrochloric acid; suitable reagents and conditions are also required for the hydroxylation step.
Second, there are other methods to follow. Or a specific substitution reaction is carried out on the naphthalene to construct a suitable intermediate, and then a multi-step transformation is carried out to realize the introduction and transformation of each group to achieve the purpose of preparation. In this process, each step of the reaction requires precise regulation of the reaction conditions, and strict requirements are placed on the purity of the raw materials and the reaction environment. Only then can high-purity 6-nitro-1-amino-2-naphthol-4-sulfonic acid be obtained.
