The name of this compound is "Benzenesulfonic Acid, 4,4 '- (1,3-Phenylenebis (Azo (4,6-Diamino-3,1-Phenylene) Azo)) Bis-, Disodium Salt". It is an organic synthetic product. The production process is as follows:
First, when taking an appropriate amount of 1,3-phenylenediamine, carefully dissolve it in an appropriate amount of dilute acid solution, stir well to fully dissolve it. Slowly add an appropriate amount of sodium nitrite solution to this solution, and control the temperature at a specific range, usually 0-5 ° C. This is a diazotization reaction. During this period, monitor the reaction progress at all times, and wait for the reaction to be complete to obtain a diazonium salt solution.
times, take another 4,6-diamino-3-sulfonic acid-based benzene, also dissolve in an appropriate solvent, and adjust to a suitable pH range. The diazo salt solution obtained above is slowly dropped into this solution under stirring, and the reaction temperature is controlled to make it fully coupled to form an azo compound intermediate. In this step, it is necessary to precisely control the reaction conditions, such as temperature, pH value and the proportion of reactants, to ensure the smooth progress of the reaction and improve the purity of the product.
Furthermore, take an appropriate amount of benzene sulfonic acid, and introduce an appropriate substituent under specific reaction conditions to prepare another key intermediate.
Then, the azo compound intermediate prepared above and the benzenesulfonic acid intermediate containing the substituent are mixed in a suitable reaction vessel in an appropriate proportion, an appropriate amount of catalyst and solvent are added, and the condensation reaction is carried out under heating and stirring conditions. During this process, the reaction temperature and time are strictly monitored to ensure that the reaction is complete and the target product is generated.
Finally, the crude product is subjected to a series of post-processing steps, such as filtration, washing, recrystallization, etc., to remove impurities and improve the purity of the product, and finally obtain a high-purity "Benzenesulfonic Acid, 4,4 '- (1,3-Phenylenebis (Azo (4,6-Diamino-3,1-Phenylene) Azo)) Bis-, Disodium Salt" product.
