Method for preparing sulfonimide compound and salts thereof The present invention relates to a process for preparing a sulfonimide compound of the structural aqueous (Rf 1 -SO 2 ) (Rf 2 -SO 2 ) NH, wherein Rf 1 and Rf 2 are independently the other, perfluoroalkyl, fluoroalkyl , Selected from the group consisting of 1 to 10 carbon atoms and fluorine fluorine selected from fluoroalkenyl, fluoraryl, fluoroallyl, and (Rf 1 -SO 2 ) (Rf 2 -SO 2 ) NH, Rf 1 SO 2 H And / or starting from the mixture M1 comprising Rf 2 SO 2 H, Rf 1 SO 2 NH 2 and / or Rf 2 SO 2 NH 2 , wherein (Rf 1 -SO 2 ) (Rf 2 -SO 2 ) NH, Rf Oxidizing the mixture M1 with an oxidant to obtain a mixture M2 comprising 1 SO 3 H and / or Rf 2 SO 3 H and Rf 1 SO 2 NH 2 and / or Rf 2 SO 2 NH 2 . A manufacturing method characterized by the above-mentioned. |
