What is the synthesis method of 3- [[4- (Phenylamino) Phenyl] Azo] Benzenesulfonic Acid Monosodium Salt
3-% 5B% 5B4-% 28 phenylamino% 29 phenyl% 5DAzo% 5D benzenesulfonic acid monosodium salt can be synthesized according to the following steps.
First take an appropriate amount of aniline, place it in the reaction kettle, add an appropriate amount of sulfuric acid, make it fully mixed, and the reaction temperature is controlled in a suitable range, so that the aniline can be smoothly sulfonated to form p-aminobenzenesulfonic acid. This step requires close attention to the fluctuation of temperature to ensure the smooth progress of the reaction.
The obtained p-aminobenzenesulfonic acid is diazotized with sodium nitrite in an acidic medium. This process requires slowly adding sodium nitrite solution dropwise, and at the same time strictly measuring the temperature and acidity of the reaction system to ensure the stable formation of diazonium salts without decomposition.
Then take an appropriate amount of N-phenylaniline, add it to the above diazonium salt reaction solution, and carry out coupling reaction under appropriate temperature and pH conditions. During the reaction, stirring should be continued to promote full contact of the reactants to improve the reaction yield. With the progress of the reaction, the color of the solution can be seen gradually changing, which is the characteristic of the reaction process.
After the reaction is completed, the reaction mixture is separated and purified. It can be neutralized first, adjusted to a suitable pH range, followed by filtration, washing and other steps to remove impurities. Finally, through the drying process, a pure 3-% 5B% 5B4-% 28 phenylamino% 29 phenyl% 5DAzo% 5D benzenesulfonic acid monosodium salt product is obtained. Throughout the synthesis process, the reaction conditions of each step need to be precisely controlled in order to achieve the ideal synthesis effect.
