Zusammenfassung:The invention relates to a method for the preparation of bis(fluorosulfonyl)-imide, the method starts from bis(chlorosulfonyl)-imide or its respective derivatives, which is reacted with HF in the presence of chlorosulfonyl isocyanate, and uses a certain extraction step for extraction of bis(fluorosulfonyl)-imide from an aqueous solution; the invention is also useful for the preparation of certainsalts of bis(fluorosulfonyl)-imide and its derivatives. 本发明涉及双(氟磺酰基)-酰亚胺的制备方法，该方法从双(氯磺酰基)-酰亚胺或其相应的衍生物开始，所述双(氯磺酰基)-酰亚胺或其相应的衍生物在氯磺酰异氰酸酯存在下与HF反应，并且使用定的萃取步骤以用于从水溶液中萃取双(氟磺酰基)-酰亚胺；本发明也可用于制备双(氟磺酰基)-酰亚胺及其衍生物的某些盐。
