What is the production and preparation method of P-Phenylene-Diamine-Ortho-Sulphonic Acid?

The method of preparing p-phenylenediamine o-sulfonic acid begins with p-nitroaniline, which is co-heated with sulfuric acid and sodium bisulfite, and then becomes p-nitroaniline o-sulfonic acid. The key to this step is to control the temperature and the material ratio to ensure that the reaction goes forward.
The obtained p-nitroaniline o-sulfonic acid is reduced. Iron powder and hydrochloric acid are commonly used as reducing agents, and sodium sulfide is also used. In the reactor, add an appropriate amount of water, iron powder and hydrochloric acid, stir it, and gradually add p-nitroaniline o-sulfonic acid. This reduction process requires temperature and pH. If the temperature is high, the yield will decrease and impurities will increase; if the pH is improper, the reaction will also be affected. After reduction, p-phenylenediamine o-sulf
After that, the work of refining is carried out. First, filter to remove unreacted iron powder and other residues, adjust the pH of the filtrate to crystallize, and then recrystallize to improve the purity. Choose a suitable solvent, such as ethanol, water, etc., crystallize many times, remove impurities, and obtain high-purity p-phenylenediamine o-sulfonic acid.
Or there are other methods. If p-phenylenediamine is the beginning, it is obtained by sulfonation. However, this way needs to be carefully selected sulfonating agent, control the reaction conditions, prevent multi-sulfonation and other side reactions. Concentrated sulfuric acid and fuming sulfuric acid are often used as sulfonating agents, slowly added at low temperature, stirred, and the reaction is closely observed. After the reaction is completed, pure p-phenylenediamine o- Overall, all methods require precise control of conditions to achieve high-yield and high-purity products.
