醚基功能化氨基酸离子液体具有其独特的低粘度和高电导率以及氨基酸的生物降解性的优点。三种醚基功能化氨基酸离子液体1-(4-甲氧基丁基)-3-甲基咪唑鎓甘氨酸([COC4mim][Gly])、1-(4-甲氧基丁基)-3-甲基咪唑鎓丙氨酸([COC4mim][Ala])和1-(4-甲氧基丁基)-3-甲基咪唑鎓苏氨酸合成了([COC4mim][Thr])。在不同的实验条件下测量了物理化学性质，包括密度、表面张力和折射率。基于希尔德布兰德理论提出的离子液体极性尺度，提出了极性系数Py的方程。我们发现它可以应用于离子液体和分子液体极性的测定。 [COC4mim][Gly]、[COC4mim][Ala] 和 [COC4mim][Thr] 的表面张力通过摩尔表面吉布斯能量和摩尔折射的定义来估计。预测值γ(pre)与相应的实验值具有非常高的线性相关性。
Ether-based functionalized amino acid ionic liquids have the advantages of its unique Contribution to low viscosity and high conductivity, as well as the biodegradability of amino acids. Three kinds of ether-based functionalized amino acid ionic liquids 1-(4-methoxybutyl)-3-methylimidazolium glycine ([COC4mim][Gly]), 1-(4-methoxybutyl)-3-methylimidazolium alanine ([COC4mim][Ala]) and 1-(4-methoxybutyl)-3-methylimidazolium threonine ([COC4mim][Thr]) were synthesized. And physicochemical properties, including density, surface tension and refraction, were measured at different experimental conditions. Based on the polarity scale of ionic liquids proposed by Hildebrand theory, an equation of the polarity coefficientPywas proposed. And we found that it can be applied into the determination of polarity for both ionic liquids and molecular liquids. The surface tension of [COC4mim][Gly], [COC4mim][Ala] and [COC4mim][Thr] was estimated by the definitions of the molar surface Gibbs energy and molar refraction. The predicted valuesγ(pre) have a very high linear correlation with the corresponding experimental ones.
