To prepare Disodium 2,2 '- (Z) -Ethene-1,2 -Diylbis {5- [ (E) - (4-Ethoxyphenyl) Diazenyl] Benzenesulfonate}, the method is as follows:
First of all, various raw materials need to be prepared, such as benzenesulfonic acid compounds with specific structures, phenylhydrazine substances containing ethoxy groups, and other auxiliary reagents such as bases, organic solvents, etc.
First take an appropriate amount of benzenesulfonic acid derivatives and dissolve them in a suitable organic solvent. This solvent needs to be able to dissolve the reactants well and have no adverse effects on the reaction, such as N, N-dimethylformamide and the like. Then, under stirring, an appropriate amount of alkali is slowly added to adjust the pH of the reaction system and create an environment conducive to subsequent reactions.
At the same time, the phenylhydrazine containing ethoxy groups is also dissolved in a suitable solvent in another container in an appropriate proportion. When the above is ready, the phenylhydrazine solution is slowly added dropwise to the reaction system containing benzenesulfonic acid derivatives. The dropwise rate should be carefully controlled to prevent the reaction from being too violent. During this process, continue to stir to make full contact with the reactants to promote the reaction.
The reaction temperature is also a key factor, and it needs to be maintained within a specific range, or under moderate heating conditions, so that the reaction can occur in a stable and suitable ring. During the reaction, the reaction progress is monitored in real time by means such as thin-layer chromatography to see if the reaction is complete.
When the reaction reaches the desired degree, the reaction mixture is cooled to room temperature, and then the appropriate separation and purification steps are performed. Or by extraction, the target product is separated from the reaction system with a suitable extractant. After that, the impurities are removed by fine purification methods such as column chromatography to obtain a pure Disodium 2,2 '- (Z) -Ethene-1,2 -Diylbis {5- [ (E) - (4-Ethoxyphenyl) Diazenyl] Benzenesulfonate} product. The entire preparation process requires strict adherence to operating specifications and attention to detail to achieve ideal results.
