제목 | Isothermal vapor-liquid equilibrium for the azeotropic systems, DIPE + ethanol with ionic liquids at 333.15 K |
초록 | Ionic liquids (ILs) could be a suitable compound to act either as extracting solvent or as entrainer for the separation of azeotropic systems by means of extractive distillation. In present work, shift of azeotropic point at 333.15K for the azeotropic systems {diisopropyl ether (DIPE) + ethanol} with trihexyltetra decylphosphonium chloride and {DIPE + ethanol} with trihexyltetradecylphosphonium bis(2, 4, 4-trimethylpentyl)phosphinate. It was reported by using headspace gas chromatography(HSGC). The experimental binary VLE data were correlated with using the NRTL and UNIQUAC equations. |
