摘要：
The invention relates to a method of treating an impure organic composition of ammonium imide, one of the substituents of which imide ion is a sulfonyl carried by a perhalogenated, advantageously perfluorinated carbon, characterized in that said composition is subjected to a step of liquid-liquid extraction by means of an aqueous phase and containing, as impurity, at least one of the chemical species chosen from halides, sulfonates and sulfinates, in particular those whose sulfur is carried by a perhalogenated carbon.
