What is the production method of 3-Hydroxy-2, 7-Naphthalenedisulfonic Acid Disodium Salt?
The preparation method of disodium salt of 3-hydroxy-2,7-naphthalene disulfonic acid, the ancient chemical industry has a cloud:
The first need is to use naphthalene as the base, first heat with sulfuric acid, and perform sulfonation. At a suitable temperature and time, when naphthalene encounters sulfuric acid, the sulfuryl group gradually enters the naphthalene ring to obtain naphthalene sulfonic acid intermediates. This step requires careful control of conditions. If the temperature is too high or the time is too long, it is easy to cause excessive sulfonation and produce other heterogeneous by-products; if the temperature is low or the time is short, the sulfonation will be insufficient, which will affect the follow-up.

In this process, the amount of oxidant and catalyst, the acid-base environment of the reaction, etc., are all key. After
, a sodium hydroxide solution is used to react with it to form 3-hydroxy-2,7-naphthalene disulfonic acid into a salt. An appropriate amount of sodium hydroxide makes the sulfonic acid groups into sodium salts. After separation and purification, such as crystallization, filtration, washing, etc., the impurities are removed, and the pure 3-hydroxy-2,7-naphthalene disulfonic acid disodium salt is finally obtained. Each step is related to the purity and yield of the product, requiring fine operation in order to obtain high-quality products.
