  Low viscous and highly conductive phosphonium ionic liquids based on bis(fluorosulfonyl)amide anion as potential electrolytes

  摘要：

  The physical and electrochemical properties of room-temperature ionic liquids based on quaternary phosphonium cations together with a bis(fluorosulfonyl)amide anion are presented in this report. The bis (fluorosulfonyl)amide-based phosphonium ionic liquids were relatively low-melting, low viscous and highly conductive when compared to those of the corresponding bis(trifluoromethylsulfonyl)amide-based ionic liquids. Particularly, the ionic liquids containing a methoxy group in the phosphonium cations indicated very low viscosities and high conductivities. The FSA-based phosphonium RTILs were thermally stable up to nearly 300 degrees C. The voltammetric analysis suggested that the bis(fluorosulfonyl)amide-based phosphonium ionic liquids showed high electrochemical stability similar to the corresponding bis(trifluoromethylsulfonyl) amide-based ionic liquids.

  用于高温酶促开环聚合的乙二醇功能化离子液体†

  摘要：

  酶促开环聚合 (ROP) 是一种制备聚丙交酯和其他聚内酯等聚酯的良性方法。这些反应通常在相对较高的温度（60-130°C）下进行，然而，对于这种热要求高的生物催化过程，缺乏与酶相容的溶剂。在这项研究中，我们制备了一系列基于磷鎓、咪唑鎓、吡啶鎓、铵或哌啶鎓阳离子头基的短链乙二醇接枝离子液体 (ILs)。大多数这些乙二醇接枝的 IL 表现出相对较低的动态粘度（30 °C 时为 33-123 mPa s），同时在分解温度下具有出色的短期热稳定性（T dcp) 在 318–403 °C 范围内。值得注意的是，在与酶促 ROP 合成条件相匹配的条件下（130 °C，7 天），这些特定任务 IL 中的一些具有出色的长期热稳定性。使用 Novozym 435 催化的 ROP，这些 IL 被证明是可行的溶剂，可用于酶促生产合理产率（30-48%）的高分子量（M w ∼20 kDa）聚（L-丙交酯）和聚（ε-己内酯）与无溶剂条件（12-14

  room temperature ionic liquids based on quaternary phosphonium cations together with a dicyanamide anion are presented in this report. The most dicyanamide-based phosphonium ionic liquids prepared were hydrophilic, except ionic liquids containing a long alkyl chain in the phosohonium cation. It was found that asymmetric phosphonium cations gave low-melting salts in combination with a dicyanamide anion

  本报告介绍了基于季phospho阳离子和双氰胺阴离子的室温离子液体的物理化学和电化学性质。所制备的大多数基于双氰胺的phospho离子液体是亲水的，除了在膦鎓阳离子中包含长烷基链的离子液体。发现不对称的nium阳离子与双氰胺阴离子结合产生低熔点的盐。与相应的铵离子液体相比，基于双氰胺的phospho离子液体表现出相对较低的粘度和较高的电导率。特别地，在phospho阳离子中含有甲氧基的离子液体显示出非常低的粘度。通过伏安法测量证实了基于双氰胺的phospho离子液体的相对较好的电化学稳定性。热重分析表明，基于双氰胺的phospho离子液体显示出比相应的铵离子液体更高的热稳定性，表明the阳离子对热稳定性的改善作用。
