The present invention provides a method for producing fluorosulfonylimides more safely, rapidly and efficiently, which enables suppression of production of by-products, and fluorosulfonylimides. The method for producing a fluorosulfonylimide salt of the present invention includes a step of reacting a fluoride compound containing at least one element selected from the group consisting of elements of Group 11 to Group 15 and Period 4 to Period 6 (excluding arsenic and antimony) with a compound represented by the following general formula (I) to give a fluorosulfonylimide salt represented by the general formula (II):
wherein R
1
denotes at least one element selected from the group consisting of elements of Group 11 to Group 15 and Period 4 to Period 6 (excluding arsenic and antimony); R
3
denotes fluorine, chlorine or a fluorinated alkyl group having 1 to 6 carbon atoms; R
4
denotes fluorine or a fluorinated alkyl group having 1 to 6 carbon atoms; and m denotes an integer of 2 or 3.
本发明提供了一种更安全、更快速、更高效地生产氟磺酰亚胺的方法,该方法能够抑制副产物的生成,并得到氟磺酰亚胺。本发明的一种生产氟磺酰亚胺盐的方法包括以下步骤:将含有来自第11至第15族元素和第4至第6周期元素(不包括砷和锑)中至少一种元素的氟化物化合物与以下通式(I)所代表的化合物发生反应,得到以下通式(II)所代表的氟磺酰亚胺盐:其中R1代表来自第11至第15族元素和第4至第6周期元素(不包括砷和锑)中至少一种元素;R3代表氟、氯或具有1至6个碳原子的氟化烷基基团;R4代表氟或具有1至6个碳原子的氟化烷基基团;m代表2或3的整数。
