| titleOfInvention | A kind of method that adopts fluorosulfonic anhydride to prepare fluorosulfonate |
| abstract | The invention provides a method for preparing fluorosulfonic acid salt by using fluorosulfonic acid anhydride, and the method comprises the following steps: (1) mixing fluorosulfonic acid anhydride, alkali metal salt and organic solvent for reaction, and obtaining a reaction liquid after solid-liquid separation; (2) Concentrating the reaction solution obtained in step (1), adding a poor solvent, crystallizing and filtering to obtain a fluorosulfonate. The method provided by the invention simplifies the operation process, reduces the generation of by-products, improves the yield and purity of the target product, and reduces the requirements on production conditions, thereby being favorable for large-scale production and application. |
