  Physical absorption of CO2 in betaine/carboxylic acid-based Natural Deep Eutectic Solvents

  摘要：

  The ability of some zwitterionic natural deep eutectic solvents (NADESs) based on N,NN-trimethylglycine (TMG) and carboxylic adds (oxalic, glycolic and phenylacetic) to act as environmentally friendly solvents for CO2 capture has been investigated. The solubility of CO2 in the NADESs was measured gravimetrically at different temperatures in the range 298.15-333.15 K, and at different pressures in the range 0.1-4 MPa. The effect of the adopted experimental conditions has been discussed. The highest uptake has been observed for phenylacetic acid/TMG DES at 313.15 K and 4 MPa (45.5 mg CO2/g DES). The efficiency of this NADES as CO2 sorbent when reused in subsequent capture cycles has been evaluated. This work might open new perspectives in developing the most appropriate combination of HBA and HOD components of the DESs and the most appropriate operative conditions for an environmentally friendly CO2 capture.

  A new group of bioinspired ionic liquids (ILs) based on glycine betaine and natural or synthetic anions was synthesized. The developed synthesis methods enabled the preparation of designed salts with high yields. The melting points for 17 of the 21 betaine-based salts were below 100 °C, allowing them to be classified as ionic liquids. Moreover, the solubilities of the novel salts in water and organic

  合成了一组新的基于甘氨酸甜菜碱和天然或合成阴离子的生物启发离子液体（ILs）。发达的合成方法能够高产率地制备设计好的盐。21种基于甜菜碱的盐中有17种的熔点低于100°C，因此可以归为离子液体。此外，检查了新型盐在水和不同极性的有机溶剂中的溶解度，并确定了它们的表面活性。在温室实验中，所有的ILs均用作农药佐剂，并确定了它们对碘磺隆的除草活性的影响。另外，确定了所获得的盐对害虫的威慑特性以及对微生物和植物的毒性的影响。事实证明，大多数国际劳工组织都是对饲料的威慑力量较弱的国家。然而，它们对被检查生物的毒性相对较低。结论是所提供的某些盐是高质量的农药佐剂，对环境安全，对储藏害虫的活性可能弱。这项工作的重要方面也是除草活性与疏水性表面的润湿性之间的关系。
