Synthesis of tetrabutylammonium bis (fluorosulfonyl) imide and related salts

摘要

The present invention adds ammonia as an ammonium salt or gas at a pressure below 0.01 Mpa to a sulfuryl fluoride solution to form an anion of bis (fluorosulfonyl) amine under conditions well suited for large scale production. To a method comprising: The bis (fluorosulfonyl) amine thus produced can be isolated by the methods described in the prior art or as an organic ion pair, such as a solid salt of an alkyl ammonium or as an ionic liquid can do.
