What is the production method of 4-Aminoazobenzene-4-Sulfonic Acid?
For 4-aminoazobenzene-4-sulfonic acid, the method of preparation is based on the principles of chemistry.
At the beginning, benzene sulfonic acid is used as the starting material to make it co-warm with concentrated nitric acid and concentrated sulfuric acid, and the method of nitrification can obtain 4-nitrobenzene sulfonic acid. This step requires careful temperature control. If the heat is too high, the side should be clumped, and the yield is not high.
Times, 4-nitrobenzene sulfonic acid is co-heated with iron powder and hydrochloric acid, and the reduction technique is performed to make the nitro group into an amino group, and 4-aminobenzene sulfonic acid is obtained. In the meantime, the amount of iron powder, the concentration of acid and the degree of heat are all factors, which are related to the purity and amount of the product.
After that, a diazonium salt solution prepared with 4-aminobenzenesulfonic acid, sodium nitrite and hydrochloric acid is coupled with aniline at low temperature. The low temperature is set to prevent the decomposition of diazonium salts. When coupling, control its pH value and the ratio of materials, so that the reaction goes forward to produce 4-aminoazobenzene-4-sulfonic acid.
There are other methods, starting with p-nitroaniline, after diazotization, and then coupling with benzenesulfonic acid, and then reducing, it can also be obtained. However, each method has its advantages and disadvantages. Those who need to use the technique observe the ease and difficulty of materials, the level of cost, the high and low yield, and the purity of the product, and choose the good method to prepare. The way to its preparation depends on the expert's intensive study of chemical principles and skilled practice of experimental skills to achieve good results.
