What is the production method of 2-Acetoamido-5-Naphthol-7-Sulfonic Acid?

The preparation method of 2-acetamido-5-naphthol-7-sulfonic acid, also known as J acid, is generally as follows:
First take naphthalene as the initial raw material and sulfonate it with sulfuric acid. Naphthalene and sulfuric acid are placed in a suitable reactor and controlled at appropriate temperature, pressure and reaction time. In this sulfonation process, sulfuric acid is used as a sulfonating agent, and the structure of naphthalene is reacted to introduce a sulfonic acid group to generate naphthalene sulfonic acid intermediates.
Then, the generated naphthalene sulfonic acid product is subjected to a step of nitration. Using nitric acid as a nitrifying agent, under specific conditions, nitro groups are re-introduced into the naphthalene ring to obtain naphthalene derivatives containing nitro and sulfonic acid groups. In this step, the control of the reaction conditions is very critical, which is related to the purity and yield of the product.
Then, the nitro-containing naphthalenesulfonic acid derivative is reduced with an appropriate reducing agent, such as iron powder, sulfide base, etc. The nitro group is reduced into an amino group to obtain a naphthalene compound containing an amino group and a sulfonic acid group.
Then the amino group is acetylated with an acetylating agent such as acetic anhydride or acetyl chloride. The amino group is converted into an acetamido group, and the naphthalene derivative containing acetamido and sulfonic acid is thus generated.
Finally, through a series of separation and purification operations, such as crystallization, filtration, washing, drying, etc., the pure 2-acetamido-5-naphthol-7-sulfonic acid product is obtained.
This preparation method is continuously optimized and improved in the process of chemical production, and strives to improve the yield, reduce costs and reduce pollution to meet the actual needs of industrial production.

What is the price range of 2-Acetoamido-5-Naphthol-7-Sulfonic Acid in the market?

2-Acetamido-5-naphthol-7-sulfonic acid, what is the price in the market? This question is quite difficult to answer, because its price is not constant, but is affected by many factors.
Looking at the past "Tiangong Kaiwu", the price of all things is related to the place of production, season, supply and demand. 2-Acetamido-5-naphthol-7-sulfonic acid is no exception. If its production is wide, the material is easy to cause, and the price is slightly cheaper; if the production is rare and difficult to collect, the price will increase.
Season is also a major reason. When production is booming, the supply of goods is sufficient, and the price may become stable but low; when it is low, the supply decreases, and the price fluctuates accordingly.
Furthermore, the price is especially influenced by the situation of supply and demand. If there are many users, the demand will exceed the supply, and the price will rise; if there is a shortage of demand, the supply will exceed the demand, and the price will decline.
Today in the market, its price ranges from tens of yuan to hundreds of yuan per kilogram. However, this is only a rough figure. The actual price still needs to be consulted by franchised merchants or checked in detail on the chemical raw material trading platform before the exact number can be obtained.
