摘要： 本文选取疏水性和疏水性离子液体混合物作为研究对象, 将疏水性离子液体1-甲基-3-n-丁基咪唑三氟甲基磺酰胺盐[BMImN(CF3SO2)2]与BMImPF6以不同的比例进行混合, 对混合离子液体及其相应单组分离子液体进行了相关物理化学性质的测试和对比, 讨论由于混合导致的物理化学效应.

关键词: 室温离子液体, 疏水性, 缔合, 混合, 协同效应

Abstract: RTIL consisting of 1-methyl-3-butyl-imidazolium(BMIm) cation and bis(trifluoromethane sulfone) imide(TFSI) anion was mixed with 1-methyl-3-n-butyl-imidazolium hexafluorophosphate(BMImPF6) at different ratios. Their room temperature conductivity, MS, LV were measured and the effect on association phenomenon by mixing is analyzed.The results demonstrate that the mixtures of ionic liquids can reduce the association degree of single ionic liquid with the better effect of properties, which mesans that the properties of the mixtures are not the average of single RTIL, but have a synergism effect.

Key words: Room temperature ionic liquid, Hydrophobicity, Association, Mixing, Synergism effect
