<P>PROBLEM TO BE SOLVED: To provide a method for stably producing high-purity lithium fluorosulfonate in a mild condition in consideration of: necessity of using highly reactive sulfur trioxide (or, oleum including the same), and necessity of taking countermeasures against difficulty of production with general reaction equipment since the production is accompanied with by-production of a gaseous inorganic fluoride producing hydrogen fluoride with hydrolysis in the method known so far; and the problem of removing acetic acid which may be adsorbed by the product with high probability even when another method is tried. <P>SOLUTION: In the method for producing lithium fluorosulfonate, lithium fluorosulfonate is obtained via a reaction step between lithium halide and fluorosulfonic acid in a nonaqueous solvent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
