The synthesis method of 7-benzamido-4-hydroxy-3- [4- (4-sulfophenyl) azophenyl] azo-naphthalene-2-sulfonic acid is not detailed in the ancient book "Tiangong Kaiwu", but I can follow the ancient method of thinking and describe it for you.
To synthesize this product, the first raw material is selected. When using compounds containing benzamide groups, hydroxyl groups, azophenyl groups and sulfonic acid groups as the basic raw materials. Naphthalene compounds containing benzamide groups and hydroxyl groups can be found first, which are the foundation of the main structure.
In addition, it is necessary to prepare an intermediate with a 4- (4-sulfophenyl) azophenyl structure. It can be achieved by diazotization and coupling reactions. Take an appropriate aromatic amine compound and treat it with a diazotization reagent to convert it into a diazo salt. Then the diazo salt is coupled with a phenolic or aramid compound containing an appropriate substituent to obtain an intermediate containing a specific azo structure.
Then, the naphthalene compound containing benzamide group and hydroxyl group is reacted with the intermediate prepared above under suitable reaction conditions. The control of reaction conditions is crucial, such as reaction temperature, reaction time, reaction solvent and catalyst selection.
In terms of temperature, the reaction can be initiated at a lower temperature at the beginning, so that the reactants contact each other and initially combine. Then, depending on the reaction process, the temperature should be moderately increased to accelerate the reaction rate and make the reaction more complete. However, the temperature should not be too high, so as not to cause side reactions and destroy the product structure.
The reaction time also needs to be precisely controlled. If it is too short, the reaction will not be fully functional and the product will be impure; if it is too long, it will consume resources and may lead to the decomposition of the product or further reaction to form impurities.
The choice of reaction solvent should be selected that can dissolve the reactants well and has no adverse effect on the reaction. Organic solvents such as dichloromethane, N, N-dimethylformamide, etc., may meet the needs.
The role of the catalyst cannot be ignored. Specific basic catalysts or acidic catalysts can be selected, depending on the specific reaction mechanism, to promote the reaction and reduce the activation energy of the reaction.
After the reaction is completed, it needs to be separated and purified. Extraction, crystallization, column chromatography and other methods can be used to remove impurities to obtain pure 7-benzamido-4-hydroxy-3-[ 4-sulfophenyl) azophenyl] azo-naphthalene-2-sulfonic acid. Therefore, following the above steps and methods, the compound may be successfully synthesized.
