  Preparation of protic ionic liquids with minimal water content and 15N NMR study of proton transfer

  摘要：

  低分子量的布朗斯特酸和胺碱被用来重复制备非常干燥、高纯度的室温质子型离子液体（PILs）。将一系列八种胺碱和六种布朗斯特酸组合，产生了48种混合物，其中18种在室温下为液态。每种混合物的相变和热分解温度被测定；而室温液体的粘度、密度和电导率也被测定。通过利用15N NMR，能够区分中性和离子化的胺碱（氨与铵型离子），这表明在作为化学计量混合物制备时，质子型离子液体是完全离子化的。然而，流动性和摩尔电导率的沃尔登图比较表明，除了当碱包含过量的质子给体基团时，大多数PIL的电导率远低于粘度所预测的值。这种差异表明，质子型离子分子形成了中性聚集体或非牛顿流体氢键网络，并出现了由多质子碱引起的次级格罗图斯质子跳跃机制。

  Three hydroxyl ammonium ionic liquids containing the alcoholic hydroxy group were synthesized that mixed with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to form integrated sorption systems with the mole ratio of 1:1. At ambient temperature and atmospheric pressure, the absorption of SO2 by integrated ionic liquid-DBU systems was investigated. The saturated absorption mole ratio of SO2/ILs was 0.30, 0.50 and 0.66, respectively. And that of SO2/ILs-DBU was 2.63, 2.83 and 2.96, respectively. The net increase in the saturated absorption mole ratio of three mixed absorption systems was close to 2.3 after deducting the SO2 saturated absorption capacity of pure ionic liquids. The results indicated that SO2 was absorbed fastly and efficiently by the mixed systems and the absorption could be completed in 0.5 h. In addition, the mixed systems had a strong regenerative ability. It’s absorption capacity and rate were hardly changed after four SO2 absorption-desorption cycle experiments.

  研究人员合成了三种含有醇羟基的羟铵离子液体，并将其与 1,8-二氮杂双环[5.4.0]十一-7-烯（DBU）混合，形成摩尔比为 1:1 的集成吸附系统。在常温常压下，研究了离子液体-DBU 一体化体系对二氧化硫的吸收。SO2/ILs 的饱和吸收摩尔比分别为 0.30、0.50 和 0.66。而 SO2/ILs-DBU 的饱和吸收摩尔比分别为 2.63、2.83 和 2.96。扣除纯离子液体的 SO2  饱和吸收能力后，三种混合吸收体系的饱和吸收摩尔比净增加值接近 2.3。结果表明，混合体系对SO2 的吸收速度快、效率高，0.5 h即可完成吸收。经过四次 SO2 吸收-解吸循环实验后，其吸收能力和吸收速率几乎没有变化。

  Low-molecular-weight Brønsted acids and amine bases were used to reproducibly prepare very dry, high-purity room-temperature protic ionic liquids (PILs). A series of eight amine bases and six Brønsted acids were combined to produce 48 mixtures, of which 18 were liquid at room temperature. The phase transitions and thermal decomposition temperatures were determined for each mixture; whereas viscosity, density and conductivity were determined for the room-temperature liquids. By utilising 15N NMR it was possible to distinguish between neutral and ionised amine bases (ammonia vs. ammonium-type ion), which indicated that the protic ionic liquids were completely ionised when made as a stoichiometric mixture. However, a Walden plot comparison of fluidity and molar conductivity indicated the majority of PILs had much lower conductivity than predicted by viscosity unless the base contained excess proton-donating groups. This disparity is indicative of protic ionic molecules forming neutral aggregates or non-Newtonian fluid hydrogen-bonded networks with a secondary Grotthuss proton-hopping mechanism arising from polyprotic bases.
