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 pieces 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:提供一种新型
离子液体,其成本低廉,环保,粘度和熔点低。
解决问题的方法:本发明是由一般式[1]表示的
离子液体的发明:其中,R1到R3和n个R4分别独立表示氢原子或具有1到4个碳原子的烷基,R5到R7各自独立表示烷基,芳基烷基或芳基,R8表示烷基,芳基烷基,芳基或由一般式[2]表示的那个物质:(其中T表示具有1到8个碳原子的烷基链,n表示1或2,R1到R7与上述相同),X表示氮原子或
磷原子,n表示1或2。当n为1时,R3和R4结合并可以与相邻的碳原子一起形成
环己烯环。此外,当X为氮原子时,R5到R7或R5到R6可以与氮原子结合形成杂环。
