Provided are an ionic liquid and a method of preparing the same. The ionic liquid includes at least one type of compound represented by (Cat
+
)(R′COO
−
). Here, the Cat
+
is a cation selected from the group consisting of quaternary ammonium, quaternary phosphonium, sulfonium, imidazolium, pyridinium, pyrazolium, piperidinium, pyrrolium, pyrrolidinium, triazolium, and a mixture of two or more thereof, and R′ is a hydrocarbon comprising at least one unsaturated bond, and having 4 to 30 carbon atoms. The ionic liquid is partially or completely miscible with various polar and/or non-polar solvents, and may be used as a solvent, a solvent additive, an electrolyte, a heat carrier, a charge carrier, a heat carrier additive, a charge career additive, or a phase transfer catalyst, at room temperatures and below. Furthermore, the cost of manufacturing the ionic liquid can be reduced.
提供了一种离子液体及其制备方法。该离子液体包括至少一种由(Cat+)(R′COO−)表示的化合物类型。这里,Cat+是从季铵盐、季磷盐、砜、咪唑盐、吡啶盐、吡唑盐、哌啶盐、吡咯盐、吡咯啉盐、三唑盐和两种或更多以上混合物组成的阳离子中选择的,R′是含有至少一条不饱和键的碳氢化合物,具有4至30个碳原子。该离子液体部分或完全与各种极性和/或非极性溶剂相容,并可用作溶剂、溶剂添加剂、电解质、热载体、电荷载体、热载体添加剂、电荷载体添加剂或相转移催化剂,在室温及以下温度下使用。此外,可以降低制造该离子液体的成本。
