What is the production method of Sodium 2, 6-Di-Tert-Butylnaphthalene-1-Sulfonate?
The process of preparing sodium 2,6-di-tert-butylnaphthalene-1-sulfonate is made after many delicate steps. First, choose 2,6-di-tert-butylnaphthalene as the starting material, which needs to be of considerable purity in order to lay the foundation for the subsequent reaction.
After that, a sulfonation reaction is carried out. Place 2,6-di-tert-butylnaphthalene in a suitable reactor and add an appropriate amount of sulfonating reagents, such as concentrated sulfuric acid or fuming sulfuric acid. The control of reaction temperature and time is crucial. Usually, the temperature should be maintained within a specific range, such as between 100 ° C and 150 ° C. After several hours of reaction, the sulfonating reagent can fully react with 2,6-di-tert-butylnaphthalene, and the sulfonic acid group is introduced at 1 position of the naphthalene ring to obtain 2,6-di-tert-butylnaphthalene-1-sulfonic acid.
Then, the step of forming a salt. In the above reaction product, slowly add a sodium hydroxide solution. During the process, the pH value of the solution should be carefully controlled, so that 2,6-di-tert-butylnaphthalene-1-sulfonic acid can fully react with sodium hydroxide to convert to 2,6-di-tert-butylnaphthalene-1-sulfonic acid In this step, the precise regulation of pH value is related to the purity and yield of the product. Generally, it is appropriate to adjust the pH value to between 7 and 8.
After the reaction is completed, the product needs to be refined. Filtration can be used to remove insoluble impurities in the reaction system. Then, the operation of crystallization is carried out, and the filtrate is concentrated and cooled to crystallize 2,6-di-tert-butylnaphthalene-1-sodium sulfonate. The crystals are washed with a suitable solvent, such as a mixed solvent of ethanol and water, to remove impurities, and finally dried to obtain a pure 2,6-di-tert-butylnaphthalene-1-sodium sulfonate product. In this way, after various steps, the compound is finally obtained.
