<P>PROBLEM TO BE SOLVED: To provide a method for producing an ionic liquid that achieves low halogen concentration while reducing the production cost. <P>SOLUTION: In the method for producing an ionic liquid having a carboxylate anion, a cation exchange resin is used. The cation of the ionic liquid is at least one selected from the group consisting of an ammonium ion, an imidazolium ion, an imidazolinium ion, a pyridinium ion, a pyrrolidinium ion, a pyrrolinium ion, a pyrazinium ion, a pyrimidinium ion, a triazonium ion, a triazinium ion, etc., and derivatives thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
