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, R1 to R3 and n moieties of R4 each independently represent hydrogen atom or alkyl group having 1 to 4 carbon atoms, R5 to R7 each independently represent alkyl group, aralkyl group, or aryl group, R8 represents 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 R1 to R7 are the same as the above-described), X represents nitrogen atom or phosphorus atom, n represents 1 or 2. When n is 1, R3 and R4 are bound and may form cyclohexene ring together with the adjacent carbon atoms. In addition, when X is nitrogen atom, R5 to R7 or R5 to R6 may form hetero ring with nitrogen atom binding thereto}.
问题:
提供一种低成本、环保、低粘度和低熔点的新型离子液体。
解决问题的方法:
本发明是通式[1]代表的离子液体的发明:
其中,R1至R3和R4的n个分子各自独立地代表氢原子或具有1至4个碳原子的烷基,R5至R7各自独立地代表烷基、芳烷基或芳基,R8代表烷基、芳烷基、芳基或通式[2]所代表的:
(其中 T 代表具有 1 至 8 个碳原子的亚烷基链,n 代表 1 或 2,R1 至 R7 与上述相同),X 代表氮原子或磷原子,n 代表 1 或 2。当 n 为 1 时,R3 和 R4 结合,可与相邻碳原子一起形成环己烯环。此外,当 X 为氮原子时,R5 至 R7 或 R5 至 R6 可与氮原子结合形成杂环}。
