摘要： The present invention provides a method for producing a disulfonylamine alkali metal salt, including a step of subjecting a disulfonylamine onium salt represented by formula [I] (wherein each of R 1 and R 2 independently represents a fluorine atom or a fluorinated alkyl group having 1 to 6 carbon atoms, provided that at least one of R 1 and R 2 represents a fluorine atom, and each of R 3 , R 4 , R 5 and R 6 independently represents a hydrogen atom or the like) to a cation exchange reaction in an organic solvent, thereby producing a disulfonylamine alkali metal salt represented by formula [II] (wherein M + represents an alkali metal cation, and R 1 and R 2 are as defined in formula [I]), and a step of filtering the organic solvent solution containing the disulfonylamine alkali metal salt through a filter having a particle retention size of 0.1 to 10 µm to obtain a filtrate.
摘要翻译： 本发明提供了制备二磺酰胺碱金属盐的方法，包括使式[I]表示的二磺酰胺鎓盐（其中R 1和R 2各自独立地表示氟原子或具有1个 至6个碳原子，条件是R 1和R 2中的至少一个表示氟原子，并且R 3，R 4，R 5和R 6各自独立地表示氢原子等）与阳离子交换反应 有机溶剂，由式[II]表示的二磺酰胺碱金属盐（其中M +表示碱金属阳离子，R 1和R 2如式[I]中所定义）），以及过滤有机 通过具有0.1〜10μm的粒子保持尺寸的过滤器含有二磺酰胺碱金属盐的溶剂溶液，得到滤液。
