1-丁基-3-甲基咪唑类离子液体的合成及表征

Synthesis and Characterization of 1-Butyl-3- methylimidazolium Ionic Liquid

作为一类环境友好的绿色溶剂或催化剂，离子液体得到了化学工作者们的广泛关注。本文就几种最常见的1-丁基-3-甲基咪唑类离子液体[Bmim]C1、[Bmim]BF4、[Bmim]PF6和[Bmim][Co（CO）4]进行了合成，并通过红外光谱、核磁共振氢谱对其结构进行了表征。考察了它们在常见有机溶剂中的溶解性，为其以后的实际应用奠定了基础。

Ionic liquids have attracted more and more attention of chemical scientists as environmentally responsible solvents and catalysts. In this paper, several kinds of 1-Butyl-3- methylimidazolium ionic liquids [Bmim]C1, [Bmim]BF4, [Bmim]PF6 and [Bmim][Co（CO）4] was prepared, and the structure of ionic liquids was characterized by IR spectrum and 1H NMR. The solubility of ionic liquids in common organic solvants was investigated, it is a essential prerequisite for application in the future.
