What is the production method of 2-Amino-6-Nitro-1-Phenol-4-Sulfonic Acid?

The preparation method of 2-amino-6-nitro-1-phenol-4-sulfonic acid follows the following steps in the past.
Starting with phenols as the base, phenol is often taken as the raw material. First, it interacts with sulfuric acid to perform the method of sulfonation. In this process, the concentration, dosage, reaction temperature and time of sulfuric acid need to be controlled in detail. When the concentration of sulfuric acid is appropriate, it is about a certain range. At a suitable temperature, it is co-placed with phenol in the reaction kettle. After several hours, a sulfonic acid group can be introduced into the phenol ring of phenol to obtain a phenolic derivative containing a sulfonic acid group.
Next, the obtained product is subjected to nitrification. The mixed acid of nitric acid and sulfuric acid is used as the nitrifying agent to control the ratio of mixed acid, reaction temperature and other factors. With the help of sulfuric acid, nitric acid has strong oxidation and nitrification activity, which can introduce nitro groups at specific positions on the benzene ring of the aforementioned products. At this stage, the temperature needs to be carefully adjusted. If it is too high, it is easy to cause side reactions and impure products. If it is too low, the reaction will be slow and take a long time.
Then, the step of amination is carried out. Ammonia or compounds containing amino groups are often used to react with phenolic products containing nitro and sulfonic acid groups under suitable catalyst and reaction conditions. The choice of catalyst is crucial, and it is necessary to conform to the reaction characteristics to promote the amino group to replace the atoms at a specific position on the benzene ring, and finally obtain 2-amino-6-nitro-1-phenol-4-sulfonic acid.
During the preparation process, the precise control of the reaction conditions at each step is the key, which is related to the purity and yield of the product. After the reaction, it needs to be separated and purified, such as crystallization, extraction, column chromatography, etc., to remove impurities and obtain pure 2-amino-6-nitro-1-phenol-4-sulfonic acid.
