  A cesium-133 nuclear magnetic resonance study of the cesium cation сomplexation by macrocyclic polyethers in hydrophobic RITLs

  摘要：

  Thermodynamic data for cesium complexes formation with 18-crown-6 (18C6, L) in five hydrophobic room temperature ionic liquids (RTIL): trioctylmethylammonium salicylate ([TOMA][Sal]), tetrahexylammonium dihexylsulfosuccinate ([THA][DHSS]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]), 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([BMIM][N(Tf)(2)]), 1-hexyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([HMIM][N(Tf)(2)]) as well as with 12-crown-4 (12C4, L) and 15-crown-5 (15C5, L) in [BMIM][N(Tf)(2)] are measured with NMR Cs-133 technique at 27-50 degrees C. Only [Cs(18C6)](+) complexes are found for [TOMA][Sal], [THA][DHSS], [BMIM][PF6], while in [BMIM][N(Tf)(2)] and [HMIM][N(Tf)(2)] both [Cs(18C6)](+) and [Cs(18C6)(2)](+) species are formed. For 12C4 and 15C5 only [CsL](+) species are registered in [BMIM][N(Tf)(2)]. For [BMIM][N(Tf)(2)] the log K-1 values are steadily increasing: 12C4 < 15C5 < 18C6. A comparative study of [Cs(18C6)](+) stability in RTILs is estimated to be in the range between water and acetonitrile with constants increasing in the order [THA][DHSS] < [TOMA][Sal] < [BMIM][PF6] < [BMIM][N(Tf)(2)] < [HMIM][N(Tf)(2)]. It is demonstrated that unlike hydrophilic RTIL the entropy change with an exception of [BMIM][PF6], promotes complex formation while the corresponding enthalpy change is either positive or gives rather small contribution to the complex stability.

The results reveal that the studied techniques could work as a novel process for the extraction of betanin from red beet juice employing ionic liquids, which have not been tested for this purpose in

• Phosphonium and Ammonium Ionic Liquids with Aromatic Anions: Synthesis, Properties, and Platinum Extraction

  Several hydrophobic long-chain quaternary ammonium and phosphonium ionic liquids (ILs) with functionalized aromatic anions were prepared following a metathesis route using tricaprylmethylammonium chloride (Aliquat 336) and trihexyl(tetradecyl)phosphonium chloride (Cyphos IL101) as precursors. The incorporation of aromatic anions bearing hydroxy-, methoxy-, thiol-, and thioether functionalities as well as tetraphenylborate anions resulted in an increased chemical stability of the ILs and an alteration of their physico-chemical properties. Furthermore, aromatic anions significantly decreased the water solubility and water uptake of both ammonium and phosphonium-based ILs. Thiol- and thioether ILs were applied for the extraction of platinum from aqueous phase using liquid phase micro-extraction. Time dependent studies showed a rapid elimination of up to 95% platinum after 30 min. With a leaching of the anion <0.01 wt-% into the aqueous media, the evaluated ILs were found to be suitable as extracting agents for platinum from aqueous solutions.

  以三(丙烯酰甲基)氯化铵（Aliquat 336）和三己基(十四烷基)氯化磷（Cyphos IL101）为前体，采用偏合成路线制备了几种具有官能化芳香阴离子的疏水性长链季铵和鏻离子液体（IL）。加入具有羟基、甲氧基、硫醇和硫醚官能团的芳香族阴离子以及四苯基硼酸阴离子后，IL 的化学稳定性得到了提高，其物理化学性质也发生了改变。此外，芳香族阴离子会明显降低铵基和鏻基 IL 的水溶性和吸水性。利用液相微萃取技术，硫醇基和硫醚基 ILs 被用于从水相萃取铂。与时间相关的研究表明，30 分钟后，铂的去除率可达 95%。阴离子在水介质中的浸出率为 0.01 wt-%，因此发现所评估的 ILs 适合用作从水溶液中萃取铂的萃取剂。
