What is the production method of 1-Naphthol-5-Sulfonic Acid (Sodium Salt)?

The preparation method of 1-naphthol-5-sulfonic acid (sodium salt) is not detailed in the ancient book "Tiangong Kaiwu", but it can be determined according to the chemical theory at that time.
Preparation of such compounds in the past, a multi-step chemical synthesis method. The first group is 1-naphthol, which can be the starting point of the reaction because it has a specific chemical structure. 1-naphthol interacts with sulfuric acid, which is strongly acidic and sulfonating. Under suitable conditions, such as temperature control, time control and in a specific reaction vessel, sulfonation can be induced.
During the reaction, the sulfonic acid group (-SO-H) of sulfuric acid will replace the hydrogen atom at a specific position of 1-naphthol. In this example, the sulfonic acid group chooses the 5 position of 1-naphthol, which is due to factors such as spatial resistance and electron cloud distribution. During the reaction process, temperature control is extremely important. If it is too high, it is easy to cause excessive sulfonation or side reactions. If it is too low, the reaction will be slow and the efficiency will be poor. Usually it needs to be maintained at a certain temperature range to make the reaction proceed smoothly.
After 1-naphthol-5-sulfonic acid is formed, the sodium salt can be reacted with sodium hydroxide (NaOH) solution. This neutralization reaction is easy to control. The acidic hydrogen of 1-naphthol-5-sulfonic acid combines with the hydroxide ion of sodium hydroxide to form water, and the sodium ion associates with the sulfonic acid ion to obtain 1-naphthol-5-sulfonic acid (sodium salt).
Finally, after various post-treatment processes such as crystallization, filtration, and drying, impurities are removed and the product is purified, and pure 1-naphthol-5-sulfonic acid (sodium salt) can be obtained. Although the ancient method may be different from the modern process, the basic principles of chemistry are the same in ancient and modern times.
