본 발명은, 설팜산 또는 이의 염들 중 하나와, 할로게노황산, 그리고 SOF, F-SO-F 및 SF로부터 선택되는 플루오르화제 적어도 1 개를 반응시킨 다음, 비스(플루오로설포닐)이미드산을 회수하는 것을 포함하는, 비스(플루오로설포닐)이미드산을 제조하기 위한 방법에 관한 것이다. 본 발명은 또한 이와 같이 제조된 비스(플루오로설포닐)이미드산으로부터 비스(플루오로설포닐)이미드의 염들을 제조하기 위한 방법에 관한 것이다. The invention relates to a method for preparing bis(fluorosulfonyl)imide acid, comprising: the reaction of sulphamic acid or one of the salts thereof with a halogenosulfuric acid and at least one fluorinating agent selected from SOF2, F-SO2-F and SF4, and the subsequent recovery of bis(fluorosulfonyl)imide acid. The invention also relates to a method for producing salts of bis(fluorosulfonyl)imide from the bis(fluorosulfonyl)imide acid thus produced.
