What is the production method of 4,5-Dihydroxy-3- [ (2-Hydroxy-5-Sulfophenyl) Azo] -2, 7-Naphthalenedisulfonic Acid Trisodium Salt?
The preparation method of 4% 2C5-dihydroxy-3- [ (2-hydroxy-5-sulfophenyl) azo] - 2% 2C7-naphthalene disulfonate trisodium salt is quite complicated.
First take 2-hydroxy-5-sulfoaniline, dissolve it in an appropriate amount of dilute acid, and prepare a diazonium salt solution by diazotization. This process requires precise temperature control, preferably at low temperature, to prevent the decomposition of diazonium salts.
Then, take 2% 2C4% 2C5% 2C7-naphthalene tetrasulfonic acid, dissolve it in an alkaline environment, and slowly add the previously prepared diazonium salt solution. In this process, continuous stirring is required to make the two fully react. This is a coupling reaction. During the reaction, close attention should be paid to the color change of the solution and the reaction process, and timely adjustment of the reaction conditions, such as temperature, pH, etc., to ensure the smooth progress of the reaction.
After the reaction is completed, the resulting mixed solution goes through a series of post-treatment steps. First, the product is precipitated from the solution by an appropriate salting-out method, and then filtered and washed to remove impurities to obtain a crude product.
The crude product still needs to be refined, and the commonly used method is to recrystallize in an appropriate solvent. Choose an appropriate solvent, dissolve the crude product, and then slowly cool down or change the proportion of the solvent to crystallize and precipitate the product. This process can effectively improve the purity of the product. After drying, 4% 2C5-dihydroxy-3- [ (2-hydroxy-5-sulfonophenyl) azo] - 2% 2C7-naphthalene disulfonate trisodium salt is obtained. The whole preparation process has strict requirements on the purity of the raw material, the control of the reaction conditions, and the fineness of the post-treatment, so that high-quality products can be prepared.
