Method for producing bis(fluorosulfonyl)imide alkali metal salt and method for producing non aqueous electrolytic solution
Provided is a method the enables easy production of bis(fluorosulfonyl)imide suitable for a non-aqueous electrolytic solution for a lithium ion secondary battery, etc. The method for producing a bis(fluorosulfonyl)imide alkali metal salt according to the present invention comprises reacting bis(fluorosulfonyl)imide with an alkali metal compound in a reaction solution containing an organic solvent, wherein the organic solvent includes at least one organic solvent (A) selected from the group consisting of carbonate solvents, cyclic ether solvents, linear ether solvents having two or more oxygen atoms in the molecule, cyclic ester solvents, sulfolane solvents, N,N-dimethyl formamide, dimethyl sulfoxide, and N-methyl oxazolidinone.
