What are the synthetic methods of Disodium 5, 7-Dinitro-8-Oxidonaphthalene-2-Sulphonate

In order to prepare disodium 5,7-dinitro-8-naphthalene oxide-2-sulfonate, there are many methods. In the past, naphthalene was used as the starting material, and by sulfonation, the naphthalene was heated with sulfuric acid to obtain naphthalene sulfonic acid. This step requires checking the temperature, duration and concentration of sulfuric acid. If the temperature is high, the reaction will be rapid, but the side effects will also increase. Therefore, when controlled at a suitable degree, about 160-180 ° C, when the number of times, naphthalene sulfonic acid is obtained.
Next, the method of nitrification is carried out. Naphthalene sulfonic acid is mixed with mixed acids of nitric acid and sulfuric acid. Nitric acid is the nitrifying agent, and sulfuric acid The key to this step is to control the nitrification position. The formation of 5,7-dinitro depends on the fine adjustment of the reaction conditions. The amount of nitric acid and the temperature of the reaction need to be carefully observed. If the temperature is high, the nitro group will easily enter other positions, resulting in impure products. Always control the temperature at a low temperature, such as 0-10 ° C, slowly drop in the mixed acid, and accompany it with strong stirring to make the reaction uniform, resulting in 5,7-dinitro-naphthalene sulfonic acid.
Then, oxidize it to obtain 5,7-dinitro-8-oxynaphthalene-2-sulfonic acid. The choice of oxidizing agent is very important, such as using suitable peroxide, reacting in a specific solvent, and adjusting pH and other conditions to promote the anterograde of oxidation.
Finally, neutralize 5,7-dinitro-8-naphthalene oxide-2-sulfonic acid with alkali, and sodium hydroxide is commonly used to form disodium 5,7-dinitro-8-naphthalene oxide-2-sulfonate. During neutralization, the process of the reaction needs to be monitored to achieve precise neutralization and obtain a pure product. Every step needs to be careful before this compound can be prepared.
