What is the preparation method of G Salt (2-Naphthol-6,8-Disulfonic Acid Dipotassium Salt)
The method of preparing G salt (2-naphthol-6,8-disulfonic acid dipotassium salt) is to take 2-naphthol as the initial material. First put 2-naphthol into the sulfonation reactor, and use sulfuric acid as the sulfonation reagent. When sulfonating, it is necessary to pay attention to the reaction temperature and time. In the initial stage, the temperature should be controlled in a moderate range, so that the sulfuric acid and 2-naphthol interact slowly, and gradually introduce the sulfonic acid group. As the reaction progresses, the temperature is moderately adjusted according to the process, and the sulfonic acid is precisely substituted based on the 6 and 8 positions of the naphthalene ring to achieve the ideal degree of sulfonation.
After the sulfonation reaction is completed Then, the product is moved to the neutralization reaction device and neutralized with potassium hydroxide solution. During the neutralization process, slowly add potassium hydroxide solution dropwise, and closely monitor the pH value of the system. When the pH value reaches a specific range, it indicates that the sulfonic acid group has fully reacted with potassium ions to form 2-naphthol-6,8-disulfonic acid dipotassium salt.
After that, the neutralization product still contains impurities and needs to be separated and purified. The common method is the crystallization method, by adjusting the temperature and adding an appropriate solvent, etc., the G salt is crystallized and precipitated from the system. Through filtration, washing and other operations, the impurities on the crystalline surface are removed, and the pure G salt (2-naphthol-6,8-disulfonic acid dipotassium salt) is finally obtained. The whole preparation process needs to be carefully controlled in each link to obtain high-quality products.
