Title:
METHOD FOR PRODUCING (FLUOROSULFONYL)PERFLUOROALKANESULFONYLIMIDE SALT
Document Type and Number:
WIPO Patent Application WO/2016/080384
Kind Code:
A1
Abstract:
[Problem] To provide a (fluorosulfonyl)perfluoroalkanesulfonylimide salt with high selectivity with high yield. [Solution] A (fluorosulfonyl)perfluoroalkanesulfonylimide salt is produced by: obtaining a solution containing a perfluoroalkanesulfonamide ammonium salt and ammonium halide by having ammonia react with a perfluoroalkanesulfonyl halide in a solvent (first step); separating and removing the ammonium halide contained in the solution by filtrating the thus-obtained solution (second step); obtaining a solution containing "a salt of a perfluoroalkanesulfonamide and an organic base" and ammonia by adding the organic base to the thus-obtained solution containing a perfluoroalkanesulfonamide ammonium salt (third step); and adding sulfuryl fluoride to the thus-obtained solution (fourth step).
