| titleOfInvention | A kind of preparation method of pyridine cyclic sulfonylimide alkali metal salt |
| abstract | The present invention provides a kind of preparation method of alkali metal salt of pyridine ring sulfonyl imide, comprising the following steps: (1) under argon protection, stirring pyridine ring sulfonyl chloride, sulfonamide, acid-binding agent and an appropriate amount of organic solvent Under the condition of mixing in the reaction bottle for reaction, forming an organic solution containing the imine compound, (2) under the stirring condition, the anhydrous alkali metal compound solid which will be 1.0 to 3 times the stoichiometric amount of the imine compound is added to the In the organic solution in step (1), the crude product of alkali metal salt of pyridine cyclic sulfonimide is obtained; (3) select a polar and weak polar compound solvent for recrystallization, filter, and obtain the target product after drying under reduced pressure, the present invention provides A method for preparing alkali metal salts of pyridine cyclic sulfonimides has the characteristics of short operation steps, easy separation and purification of products, high yield and high purity of products, and the like, and has important industrial application value. |
