Abstract
Problem: Providing a novel ionic liquid, which is low-cost, environment-friendly, and has low viscosity and melting point. Means for Solving the Problem: The present invention is the invention of the ionic liquid represented by the general formula [1]: {wherein, Rto Rand n pieces of Reach independently represent hydrogen atom or alkyl group having 1 to 4 carbon atoms, Rto Reach independently represent alkyl group, aralkyl group, or aryl group, Rrepresents alkyl group, aralkyl group, aryl group, or the one represented by the general formula [2]: (wherein T represents alkylene chain having 1 to 8 carbon atoms, n represents 1 or 2, and Rto Rare the same as the above-described), X represents nitrogen atom or phosphorus atom, n represents 1 or 2. When n is 1, Rand Rare bound and may form cyclohexene ring together with the adjacent carbon atoms. In addition, when X is nitrogen atom, Rto Ror Rto Rmay form hetero ring with nitrogen atom binding thereto}.
