氯离子基离子液体在各种离子液体中具有独特的重要性。然而，它们通常具有很强的粘性，研究它们与分子溶剂的混合对它们的实际应用具有重要意义。在这项工作中，测量了1-丁基-3-甲基咪唑氯和几种质子/非质子溶剂的二元混合物的粘度和电导率，并讨论了分子间相互作用和微观结构的基本信息。结果表明，具有较高介电常数和氢键酸度的分子溶剂将更有效地促进氯离子离子的解离，并改善相应应用的输运性能。
Chloride anion-based ionic liquids (ILs) have unique importance among various ILs. Nevertheless, they are usually very viscous, and the study on their mixtures with molecular solvent is important for their practical application. In this work, the viscosities and conductivities of the binary mixtures of 1-butyl-3-methylimidazolium chloride and several protic/aprotic solvents were measured, and the underlying information about intermolecular interaction and microscopic structure was discussed. The result showed that the molecular solvents which have relatively high dielectric constant and hydrogen-bond acidity will be more efficient in promoting the dissociation of chloride anion-based ILs and improving the transport properties of corresponding applications.
