  Synthesis and Properties of Seven Ionic Liquids Containing 1-Methyl-3-octylimidazolium or 1-Butyl-4-methylpyridinium Cations

  摘要：

  Syntheses are reported for ionic liquids containing 1-methyl-3-octylimidazolium or 1-butyl-4-methylpyridinium cations and trifluoromethyl sulfonate, dicyanamide, bis(trifluoromethylsulfonyl) imide, or nonafluorobutyl sulfonate anions. Densities, melting points, glass-transition temperatures, solubilities in water, and polarities have been measured. Ionic liquids containing pyridinium cations exhibit higher melting points, lower solubility in water, and higher polarity than those containing imidazolium cations.

• A Simple Halide-to-Anion Exchange Method for Heteroaromatic Salts and Ionic Liquids

  A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A− form) in non-aqueous media. The anion loading of the AER (OH− form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A− form) method in organic solvents was

  Further studies on the application of an AER (A(-) form) method broadened the anion exchange scope of representative ionic liquids and bis(imidazolium) systems. Depending on the hydrophobicity nature of the targeted imidazolium species and counteranions, different organic solvents were used to swap halides for assorted anions, proceeding in excellent to quantitative yields.

  对AER（A（-）形式）方法应用的进一步研究拓宽了代表性离子液体和双（咪唑鎓）体系的阴离子交换范围。根据目标咪唑类物质和抗衡阴离子的疏水性，使用不同的有机溶剂将卤化物交换为各种阴离子，从而以优异的产率获得定量的收率。
