<P>PROBLEM TO BE SOLVED: To provide an industrially simple method for producing an ionic liquid capable of giving combinations of various cations and anions. <P>SOLUTION: The method for producing an ionic liquid includes a step of reacting an ammonium salt of a sulfuric ester (1), an ammonium salt of a phosphoric ester (2) or an ammonium salt of a sulfonic acid with a nitrogen-containing compound. In formula (1), R<SP POS="POST">1</SP>indicates a 1C-20C substituted or unsubstituted, straight-chained, branched or cyclic alkyl group, a 6C-30C substituted or unsubstituted aryl group, or a 7C-31C substituted or unsubstituted arylalkyl group; A<SP POS="POST">1</SP>indicates a 2C-4C substituted or unsubstituted, straight-chained or branched alkylene group; and n indicates an integer of 0-50. In formula (2), R<SP POS="POST">2</SP>and R<SP POS="POST">3</SP>indicate each independently a hydrogen atom, a 1-20C substituted or unsubstituted, straight-chained, branched or cyclic alkyl group, a 6-30C substituted or unsubstituted aryl group, or a 7-31C substituted or unsubstituted arylalkyl group, provided that R<SP POS="POST">2</SP>and R<SP POS="POST">3</SP>do not simultaneously indicate a hydrogen atom; A<SP POS="POST">2</SP>and A<SP POS="POST">3</SP>indicate each independently a 2-4C substituted or unsubstituted, straight-chained or branched alkylene group; and m and q indicate each independently an integer of 0-50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
