What is the preparation method of 1-Naphthalenesulfonic Acid?

The preparation method of 1-naphthalene sulfonic acid has been known for a long time. In the past, this acid was often prepared with naphthalene as the starting material, so that it was co-heated with sulfuric acid to undergo a sulfonation reaction.
First take pure naphthalene and mix it with concentrated sulfuric acid in a certain proportion. In the reactor, slowly heat up to ensure that the temperature is properly controlled. This reaction requires careful operation. If the temperature is too high, side reactions will occur frequently, affecting the purity of the product; if the temperature is too low, the reaction rate will be slow and take a long time.
Usually the reaction temperature is maintained between hundreds of degrees, fine-tuned according to the specific situation. During the reaction, pay close attention to the changes in the kettle, and the naphthalene interacts with sulfuric acid to gradually form 1-naphthalene sul After the reaction is completed, the product needs to be followed up.
