What is the production method of 1-Methyl-2-Nitrobenzene-4-Sulfonic Acid?

The preparation method of 1-methyl-2-nitrobenzene-4-sulfonic acid is generally as follows.
First, toluene is used as the initial raw material and is first sulfonated. Put toluene in a specific reactor, slowly inject concentrated sulfuric acid in proportion, and control the reaction temperature and time at the same time. In this process, it is necessary to pay close attention to the reaction situation, because the temperature is too high to easily cause side reactions. After the sulfonation reaction is completed, p-toluenesulfonic acid can be obtained. The principle of this reaction is that the sulfonic acid group replaces the hydrogen atom on the toluenesulfonic ring to form p-toluenesulfonic acid.
Next, p-toluenesulfonic acid is nitrified. Under appropriate reaction conditions, a mixture of concentrated nitric acid and concentrated sulfuric acid is added to p-toluenesulfonic acid. This step of the reaction must be handled with caution, because it has certain risks. Under the action of concentrated sulfuric acid, nitrate is used as an electrophilic reagent to attack the benzene ring, and nitro is introduced at the ortho-position of the sulfonic acid group to obtain 1-methyl-2-nitrobenzene-4-sulfonic acid. In this process, the precise control of the reaction conditions is extremely critical. Factors such as temperature and the proportion of mixed acids will have a significant impact on the purity and yield of the product.
Another preparation method is to use toluene as the starting material. The nitration reaction is carried out first, so that the nitro group is introduced into the toluenesulfene ring. Then, the sul However, in practice, due to the localization effect of nitro groups, it is difficult to control the selectivity and purity of the product, so the former method is more commonly used. In short, the preparation of 1-methyl-2-nitrobenzene-4-sulfonic acid requires fine control of the reaction conditions in each step to obtain the ideal product.
