What is the production method of 2-Amino-5-Methylbenzenesulfonic Acid?

2-Amino-5-methylbenzenesulfonic acid, the method of preparation, although the ancient book "Tiangong Kaiwu" does not explicitly state this thing, it can be deduced according to the ancient chemical process.
Ancient sulfonic acids are often made by sulfonation. To make 2-amino-5-methylbenzenesulfonic acid, you can first take 2-methylaniline as the base material. This 2-methylaniline is an organic compound, with amino groups and methylbenzene based on the benzene ring.
When sulfonating, a sulfonating agent is used. The ancient process often uses sulfuric acid as the sulfonating agent. Sulfuric acid, a strong acid, has strong oxidizing and sulfonating ability. Mix 2-methylaniline with sulfuric acid at a suitable temperature to make it react. Temperature control is crucial. If the temperature is too high, the reaction will be too fast, prone to side reactions, resulting in impure products; if the temperature is too low, the reaction will be slow and time-consuming.
During the reaction, the sulfonic acid group of sulfuric acid (-SO-H) replaces the hydrogen atom on the benzene ring, and then forms 2-amino-5-methylbenzenesulfonic acid. However, the product obtained by this reaction, or containing impurities, needs to be purified by refining. Ancient refining, often by crystallization and filtration. The reaction solution is cooled, the product crystallizes and precipitates, and then the impurities are removed by filtration to obtain a relatively pure 2-amino-5-methylbenzenesulfonic acid.
Although this preparation method is based on ancient principles, the ancient process may be simple, but today's production method must be more delicate, but its basic principles may be similar.
