3-Hydroxynaphthalene-2, What is the production method of 7-Disulfonic Acid Disodium Salt?

The preparation method of 3-hydroxy naphthalene-2,7-disulfonic acid disodium salt is made from naphthalene as the starting material and has undergone many delicate chemical changes.
At the beginning, the naphthalene is sulfonated. The naphthalene is placed in a suitable reaction vessel and supplemented with sulfuric acid and other sulfonating reagents. At a specific temperature and reaction time, the sulfonic acid group in the sulfuric acid (-SO 🥰 H) ingeniously replaces the hydrogen atom on the naphthalene ring to form naphthalene sulfonic acid derivatives. This step of the reaction is quite critical. The control of temperature and reagent ratio is extremely important, and a slight difference will affect the formation of subsequent products.
Next, the obtained naphthalene sulfonic acid derivatives are hydroxylated. Under suitable reaction conditions, a hydroxyl group (-OH) is introduced. This process often requires the help of a specific catalyst to promote the smooth progress of the reaction in the direction of generating 3-hydroxynaphthalenesulfonic acid derivatives.
Then, sulfonate again. This step aims to precisely introduce the second sulfonic acid group at a specific position of the 3-hydroxynaphthalenesulfonic acid derivative, and then generate 3-hydroxynaphthalenesulfonic acid. This step requires high selectivity of the reaction check point, which can only be achieved by relying on delicate reaction conditions and suitable reaction aids.
