Title:
METHOD FOR PRODUCING IONIC LIQUID
Document Type and Number:
Japanese Patent JP2012072130
Kind Code:
A
Abstract:

To provide an industrially simple method for producing an ionic liquid capable of giving combinations of various cations and anions.

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), R1 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; A1 indicates a 2C-4C substituted or unsubstituted, straight-chained or branched alkylene group; and n indicates an integer of 0-50. In formula (2), R2 and R3 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 R2 and R3 do not simultaneously indicate a hydrogen atom; A2 and A3 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.
