1, What is the preparation method of 3-Phenylene-Diamino-4-Sulphonic Acid?

1% 2C3-phenylene-diamino-4-sulfonic acid, that is, 1,3-phenylenediamine-4-sulfonic acid, is prepared as follows:
First take an appropriate amount of m-phenylenediamine and slowly add it to a certain amount of pre-cooled concentrated sulfuric acid. This process requires careful operation. Because concentrated sulfuric acid is highly corrosive and water-absorbing, it will release a lot of heat at the same time. Therefore, it is necessary to continuously stir when adding to make m-phenylenediamine evenly dispersed and prevent local overheating.
Subsequently, the reaction system is heated to a specific temperature range, generally between 100 ° C and 150 ° C. This temperature range is conducive to the progress of the sulfonation reaction. During the heating process, close attention should be paid to the reaction conditions to ensure that the temperature is stable and does not fluctuate widely.
Continue to stir and maintain the reaction temperature for a period of time to make the reaction fully proceed. During this period, the amino o-sites in the m-phenylenediamine molecule will sulfonate with concentrated sulfuric acid, and gradually form 1,3-phenylenediamine-4-sulfonic acid.
After the reaction is completed, until the reaction system cools down, the product can be separated and purified by appropriate methods. For example, the reaction solution can be diluted by pouring a large amount of ice water. At this time, 1,3-phenylenediamine-4-sulfonic acid will precipitate in solid form, and the crude product can be obtained by filtration. After that, further purification by recrystallization and other means can obtain relatively pure 1,3-phenylenediamine-4-sulfonic acid. It should be noted that the entire preparation process should be operated in a well-ventilated environment, and operators should take protective measures to avoid harm to the body caused by concentrated sulfuric acid and other substances.
