摘要: Ionic liquids (ILs) can replace conventional solvents in separation processes, such as extractive distillation (ED), because of their ability to selectively separate azeotropic/close boiling mixtures. Four case studies were selected: ethanol/water (1-ethyl-3-methylimidazolium dicyanamide, [emim][N(CN)2], and ethylene glycol, EG), 1-hexene/n-hexane (no suitable IL found), methylcyclohexane/toluene (1-hexyl-3-methylimidazolium tetracyanoborate, [hmim][B(CN)4], N-methyl-2-pyrrolidone, NMP), ethylbenzene/styrene (4-methyl-N-butylpyridinium tetrafluoroborate, [4-mebupy][BF4], sulfolane). Pilot plant experiments proved that the developed models for ED could well describe experimental results.
