What is the production process of 2-Naphthol-3,6-Disodium Disulfonate?

2-Naphthol-3,6-Disodium Disulfonate (2-Naphthol-3,6-Disodium Disulfonate), also known as R salt, its preparation process was quite delicate in the past.
Initially, 2-naphthol is used as the basic raw material. Place 2-naphthol in a specific reactor and slowly inject concentrated sulfuric acid in an appropriate proportion. In this step, the temperature and reaction time need to be carefully controlled. Generally, the temperature is usually maintained between 130-160 ° C for about 3-5 hours. Concentrated sulfuric acid and 2-naphthol then sulfonate, and the sulfonic acid group is cleverly attached to the naphthalene ring to form a mixture of 2-naphthol-3-sulfonic acid and 2-naphthol-6-sulfonic acid.
After that, the mixture is moved into another reaction apparatus, and the soda ash (sodium carbonate) solution is slowly added. This process needs to be handled with caution to prevent overreaction. Sodium carbonate interacts with the sulfonic acid compound to neutralize and generate the corresponding sodium salt. At this moment, 2-naphthol-3-sulfonic acid and 2-naphthol-6-sulfonate sodium coexist in the reaction system.
Then take this mixed sodium salt solution, concentrate and crystallize, so that the salt precipitates from the solution. When crystallizing, factors such as temperature and stirring rate need to be carefully controlled to obtain high-quality crystals. The obtained crystals are filtered and washed to remove impurities, and finally pure 2-naphthol-3,6-disulfonate can be obtained.
The whole preparation process, each step is interlocked, and temperature, raw material ratio, reaction time, etc. are all key factors. A slight difference may affect the purity and yield of the product.
