METHOD FOR PRODUCING LITHIUM OR SODIUM BIS(FLUOROSULFONYL)IMIDIDE

摘要

The invention relates to a process for the preparation of a bis(sulphonato)imide salt of formula: (III) (SO3)N(SO3)3C+(III) where C+ represents a monovalent cation, comprising the reaction of amidosulphuric acid of formula: (OH)SO2NH2(I) with a halosulphonic acid of formula: (OH)SO2X(II) where X represents a halogen atom, and comprising a reaction with a base which is a salt formed with the cation C+. The invention also relates to a process for the preparation of bis(fluorosulphonyl)imide acid of formula: F(SO2)NH(SO2)F(V) and to a process for the preparation of lithium bis(fluorosulphonyl)imide salt of formula: F(SO2)N(SO2)F Li+.(VII)
