METHOD FOR PRODUCING LITHIUM OR SODIUM BIS(FLUOROSULFONYL)IMIDIDE

摘要

The invention relates to a process for the preparation of a bis (sulfonate) imide salt of the formula: (III) (SO 3 -) N - (SO 3 -), 3C + wherein C + represents a monovalent cation, comprising the reaction of the amidosulphuric acid of the formula: (I) (OH) -SO 2 -NH 2 with a halosulfonic acid of the formula: (II) (OH) -SO 2 -X where X represents a halogen atom, and comprising a reaction with a base which is a salt formed with the C + cation. The invention also relates to a process for preparing a bis (fluorosulfonyl) imide acid of the formula: (V) F- (SO 2) -NH- (SO 2) -F and a process for the preparation of a bis (fluorosulfonyl) salt lithium imide of formula: (VII) F- (SO2) -N- (SO2) -F, Li +.
