METHOD FOR PRODUCING BIS(FLUOROSULPHONYL)IMIDE

摘要

Disclosed is a method for producing bis(fluorosulphonyl)imide capable of continuous production while controlling the generation of carbon dioxide gas and reaction heat. A method for producing bis(fluorosulphonyl)imide characterized by comprising a process for mixing urea in fluorosulfuric acid without being reacted and preparing an unreacted liquid mixture, a process for supplying the unreacted liquid mixture to a heated reaction vessel and producing a reaction liquid containing at least bis(fluorosulphonyl)imide and a process for recovering the reaction liquid from the reaction vessel is used.
