The present disclosure relates to a process for preparing a bis (fluorosulfonyl) imine salt and a process for preparing an alkali metal salt of a bis (fluorosulfonyl) imine from the bis (fluorosulfonyl) imine salt. More specifically, the present invention provides a novel process for the production of these bis (fluorosulfonyl) imine salts, which process can be implemented on an industrial scale, and which process provides high purity bis (fluorosulfonyl) imine salts. 本披露涉及一种用于制备双(氟磺酰基)亚胺盐的方法以及一种用于由所述双(氟磺酰基)亚胺盐制备双(氟磺酰基)亚胺的碱金属盐的方法。更具体地，本发明提供一种用于生产这些双(氟磺酰基)亚胺盐的新方法，该方法在工业规模上可实施，并且该方法提供高纯度的双(氟磺酰基)亚胺盐。
