Manufacturing Method For bis-Fluoro Sulfonyl Imide Salt And bis-Fluoro Sulfonyl Imide Ammonium Salt

摘要

The present invention relates to a process for producing a bis (fluorosulfonyl) imide ammonium salt having a low content of impurities, comprising the steps of (A) introducing a reaction solvent and ammonium fluoride into a reaction vessel, cooling the reaction vessel temperature to 0 to 5 ° C ; (B) adding dropwise bis (chlorosulfonyl) imide to the cooled reaction vessel, raising the temperature to 80 to 100 캜 and reacting for 2 to 4 hours; And (C) after completion of the reaction, cooling at room temperature, followed by filtration to obtain a bis (fluorosulfonyl) imide ammonium salt, and a process for producing the bis (fluorosulfonyl) imide ammonium salt.
