报道了一种铵基熔盐双（三氟甲基磺酰基）酰胺-18-冠-6（1/1）铵[NH 4+·18 C6][Tf 2N-]（Tf= SO2 CF 3）的合成与表征。拉曼光谱表明，[NH 4+·18 C6][Tf 2 N-]由18 C6包裹的NH 4+离子和Tf 2 N-阴离子组成。[NH_4 ~+·18C_6][Tf_2N ~-]的熔点约为100 ℃。在140 ℃下，[NH 4+·18 C6][Tf 2N-]的粘度为14.7 mPa s，电导率为8.0 mS cm-1，密度为1.23 g cm-3。这些性能与普通离子液体相当。
We report synthesis and characterization of an ammonium-based molten salt, ammonium bis (trifluoromethylsulfonyl) amide-18-crown-6 (1/1), ie [NH4+· 18C6][Tf2N–](Tf= SO2CF3). Raman spectra shows [NH4+· 18C6][Tf2N–] consists of NH4+ ion encapsulated by 18C6 and Tf2N–anion. The melting point of [NH4+· 18C6][Tf2N–] was around 100 C. At 140 C, the viscosity of [NH4+· 18C6][Tf2N–] was 14.7 mPa s, the conductivity was 8.0 mS cm–1, and the density was 1.23 g cm–3. These properties were comparable to those of common ionic liquids.
