  Hydrophobic and low-density amino acid ionic liquids

  摘要：

  A series of tetraalkylphosphonium amino acid salts was synthesized to determine the effect of ion structure, in particular the length of alkyl chains, on physico-chemical properties such as density, viscosity, glass transition temperature, and decomposition temperature. The resulting alkylphosphonium amino acid ionic liquids (AAILs) all had low density, from 0.886 to 0.945 g cm(-3) at 25 degrees C. The density was tunable by varying the alkyl-chain length, regardless of the symmetry of the phosphonium cations. When the alkyl chains on the phosphonium cation were hexyl or longer, the AAILs were phase-separated upon mixing with water because of their hydrophobicity, and floated on top of the water phase. The water content in the ILs depended on the amino acid side chains and on the alkyl-chain length on the cations. (C) 2010 Elsevier B.V. All rights reserved.

  comparison of their properties, and their applications as bifunctional catalysts for CO2 insertion into epoxides. The synthetic procedures to obtain ILs rely on anion exchange and acid–base reactions, including an innovative route for the synthesis of molybdate ionic liquids (Mo-ILs) using a halide-free organic IL precursor. The use of Mo-ILs as catalysts for CO2 fixation was investigated using 1,2-epoxyhexane

  在此，我们描述了一系列钼酸盐和多氧钼酸盐离子液体 (IL) 的合成、它们的完整光谱表征（FT-IR、1 H-、13 C-、31 P- 和95 Mo-NMR 和 ICP-MS），它们的性能比较，以及它们作为 CO 2插入环氧化物的双功能催化剂的应用。获得离子液体的合成程序依赖于阴离子交换和酸碱反应，包括使用无卤化物有机离子液体前体合成钼酸盐离子液体 (Mo-IL) 的创新途径。Mo-ILs作为CO 2催化剂的用途使用 1,2-环氧己烷作为模型底物对固定进行了研究。在 2.5 mol% 的四丁基钼酸铵存在下，在T = 120 °C、p 0 (CO 2 ) = 30 bar、t = 9 h、无溶剂条件下且不添加任何物质的情况下，碳酸己烷的产率高达 86%卤化物助催化剂。底物范围扩大到其他12种端环和内环氧化物；此外，反应扩大到 2 g 底物，催化剂的可回收性被证明高达 5 次循环。
