<P>PROBLEM TO BE SOLVED: To provide ionic liquids excluding ionic liquids composed of cations based on quarternary nitrogen or phosphorus with nucleus selected from a quarternary ammonium cation, pyrrolidinium cation, imidazolium cation, pyridinium cation or the like. <P>SOLUTION: The invention relates to the ionic liquid comprising an anion and a cation wherein the cation is a nitrogen-containing cation of the formula N+HRR'R", (wherein the formula: R is a hydrocarbyl group optionally interrupted by one or more ether or thioether linkages, and optionally substituted with one or more substituents selected from nitrogen-containing functional groups, alkyl, alkenyl, alkoxy, hydroxy, carbonyl and carboxy groups, R' and R", which may be the same or different, each represents H or the same to the R, and any two or three of R, R' and R" may be joined together with the N to form a cyclic group). <P>COPYRIGHT: (C)2012,JPO&INPIT |
