What is the preparation method of 1-Naphthalenesulfonic Acid, 6-Amino-?

The method of preparing 6-amino-1-naphthalenesulfonic acid has also had its own path in the field of chemical creation throughout the ages.
In the past, the method was mostly based on 1-naphthalenesulfonic acid. First take an appropriate amount of 1-naphthalenesulfonic acid and place it in a suitable reactor. The kettle needs to be made of fine material and can withstand the temperature and pressure changes of the reaction. Then, add a specific nitrifying agent to the kettle, such as the mixed acid of nitric acid and sulfuric acid. When adding, it needs to be slow and uniform to prevent overreaction. The ratio of mixed acid and the rate of addition are both key, which are related to the direction of the reaction and the purity of the product. After adding, the temperature should be controlled within a certain range. This temperature should be stable and should not fluctuate greatly. After nitration reaction, 6-nitro-1-naphthalenesulfonic acid can be obtained.
However, this product is not a final state and needs to be converted. Then 6-nitro-1-naphthalenesulfonic acid is taken out, another kettle is placed, and a suitable reducing agent is added, such as iron powder and hydrochloric acid system, or a combination of hydrogen and catalyst. Taking hydrogen and catalyst as an example, palladium and carbon are commonly used in catalysts. Under suitable temperature and pressure, hydrogen and nitro undergo a reduction reaction, and the nitro gradually converts to an amino group, resulting in 6-amino-1-naphthalenesulfonic acid.
The method after
, or by means of new organic synthesis techniques. Using naphthalene as the starting material, the sulfonic acid group is introduced through the sulfonation reaction first, and then the nitro group is introduced at the 6 position precisely by the newly invented nitrogenation method, and the reagents and conditions used are milder, and the side reactions are less. In the subsequent reduction step, a new reducing agent or catalytic system is also used to improve the reaction efficiency and product yield. Or in the reaction, with the help of phase transfer catalysts and other auxiliaries, the reaction is carried out efficiently in a heterogeneous system, and the product is easy to separate and purify. All these are methods for preparing 6-amino-1-naphthalenesulfonic acid.
