摘要：

In this work, a series of imidazolium-based and pyridinium-based ionic liquids (ILs) with suitable density, viscosity, and other properties are synthesized and employed for the absorption of methyl chloroacetate (MC). The saturated absorption of [Bmim][SCN] reached 0.9409 g MC/g ILs, and the saturated absorption of [BPy][SCN] reached 0.8455 g MC/g ILs at atmospheric pressure, 40 °C. Absorption-desorption cycling experiments with [Bmim][SCN] and [BPy][SCN] were carried out. Both ILs showed excellent cycling and regeneration performance, and the chemical structures before and after absorption did not change significantly. The interaction between ILs and MC molecules has been analyzed from a microscopic point of view with the aid of quantum chemical calculations. The vapor–liquid equilibrium data of [Bmim][SCN] + MC, and [BPy][SCN] + MC are determined for the two systems at different compositions in the range of 353.15–393.15 K. The measured data are correlated using the UNIFAC activity coefficient model. © 2024
