| titleOfInvention | Synthesis method of bis (fluorosulfonyl) imide |
| abstract | The invention discloses a synthetic method of difluoride sulfimide, which comprises the following steps: 1) benzylamine compounds and sulfuryl fluoride react in a solvent in the presence of a catalyst and alkali to generate N-benzyl bis-fluorosulfonyl imide compounds; 2) carrying out catalytic hydrogenation reaction on the N-benzyl bis (fluorosulfonyl) imide compound to obtain bis (fluorosulfonyl) imide. The synthetic method of the bis-fluorosulfonyl imide provided by the invention has the advantages of easily available raw materials, no corrosion, low requirement on equipment, no hydrogen fluoride high-pressure fluorination reaction in the synthetic process, no pollution in the reaction process, greatly improved reaction safety and simple reaction steps, and the obtained bis-fluorosulfonyl imide can be further reacted with carbonate to directly prepare high-purity salt, and can meet the use requirement of a lithium battery without further purification. |
