However, the reaction is complicated and there are many products. To obtain 1-naphthol-5-sulfonic acid, it must be carefully separated before it can be reached.
In the early stage of sulfonation, sulfuric acid is often used as a agent. At a specific temperature and duration, naphthalene comes into contact with sulfuric acid. Temperature is very important. If it is slightly higher, there will be more by-products, and if it is slightly lower, the reaction will be slow. After the sulfonation is completed, the product contains a variety of isomers, and 1-naphthol-5-sulfonic acid is mixed in it, which is difficult to separate. It needs to be extracted with a special solvent or crystallized many times before purification.
Today's production method is advanced in technology. With the method of catalytic sulfonation, a special catalyst is introduced, which can increase the reaction selectivity and greatly increase the proportion of 1-naphthol-5-sulfonic acid in the product. The catalyst can reduce the activation energy of the reaction, so that the reaction can be carried out efficiently under mild conditions. And the subsequent separation steps have also been improved. High-purity 1-naphthol-5-sulfonic acid can be easily and accurately obtained by high-performance chromatography or new membrane separation methods.
