<p>A process for the preparation of fluorine-containing sulfonyl imide compounds, which includes subjecting a mixture of a fluorine-containing sulfonyl imide compound represented by (Rf1SO2)(Rf2SO2)NH (1) and a sulfonic acid compound represented by RfSO3H (2) to distillation in the presence of water. In formula (1), Rf1 and Rf2 are each fluorine, or linear or branched C1-4 perfluoroalkyl, with the proviso that a case wherein both Rf1 and Rf2 are fluorine is excepted. In formula (2), Rf is linear or branched C1-4 perfluoroalkyl.</p> |
