离子液体作为一种可替代的、可持续的溶剂被广泛讨论，不仅是因为它们独特的化学性质，而且还因为它们极低的蒸汽压和——至少在某些情况下——相对较高的热稳定性。本文介绍了一些纯离子液体和负载离子液体的蒸汽压数据和分解动力学。基于这些结果，介绍了确定纯离子和负载离子挥发性和稳定性的一般策略，以及关于分解和蒸发的最高工作温度的标准。
Ionic liquids (ILs) are widely discussed as alternative, sustainable solvents not only because of their unique chemical properties, but also because of their extremely low vapor pressure and – at least in some cases – relatively high thermal stability. In this work the vapor pressure data and kinetics of decomposition are presented for some selected pure and supported ionic liquids. Based on these results general strategies to determine the volatility and stability of pure and supported ILs as well as criteria for the maximum operation temperature with regard to decomposition and evaporation are introduced.
