To prepare Sodium + 6-Amino-5- { (E) - [4-Chloro-2- (Trifluoromethyl) Phenyl] Diazenyl} -4-Hydroxynaphthalene-2-Sulfonate, the synthesis method is as follows:
First, when 4-chloro-2- (trifluoromethyl) aniline is used as the starting material, the diazotization reaction occurs first. Take an appropriate amount of 4-chloro-2- (trifluoromethyl) aniline and dissolve it in an appropriate amount of inorganic acid solution, common such as hydrochloric acid or sulfuric acid. The mixture is cooled to a low temperature, generally 0-5 ° C. Then, slowly add the sodium nitrite solution dropwise. During the process, the temperature should be strictly controlled to avoid excessive temperature and ensure the smooth progress of the diazotization reaction to generate diazonium salts.
Secondly, 6-amino-4-hydroxy-2-naphthalenesulfonic acid is used as the coupling component. Dissolve it in a suitable alkaline solution, such as sodium carbonate or sodium hydroxide solution, and adjust it to a suitable pH value, generally in the weakly basic range. Under stirring, the diazonium salt obtained above is slowly added to the alkaline solution of 6-amino-4-hydroxy-2-naphthalenesulfonic acid, and the reaction temperature is controlled, usually between 5-15 ° C. During the reaction, the reaction process needs to be continuously monitored, which can be achieved by means of thin-layer chromatography. After the reaction is complete, the target product Sodium + 6-Amino-5- { (E) - [4-Chloro-2- (Trifluoromethyl) Phenyl] Diazenyl} -4-Hydroxynaphthalene-2-Sulfonate is formed in the solution.
Finally, the reaction product is separated and purified. Filtering methods can be used to separate the solid product, and then the solid is washed with an appropriate solvent to remove impurities. The product is further purified by recrystallization, etc., a suitable solvent is selected, the product is dissolved by heating, and the product is slowly cooled to allow the product to crystallize and precipitate to obtain high-purity Sodium + 6-Amino-5- { (E) - [4-Chloro-2- (Trifluoromethyl) Phenyl] Diazenyl} -4-Hydroxynaphthalene-2-Sulfonate.
