摘要

1- 辛烯+1-乙基-3-甲基咪唑鎓乙酸盐（[EMIM][Ac]）、1-辛烯+1-丁基-3-甲基咪唑鎓乙酸盐（[BMIM][Ac]）、1-辛烯+1-丁基-3-甲基咪唑鎓四氟硼酸盐（[BMIM][BF4]）二元体系的液液平衡（LLE）、2-hexanone + [EMIM][Ac] 和 2-hexanone + [BMIM][Ac] 以及 1- 辛烯 +2-hexanone + [EMIM][Ac], 1- 辛烯 +2-hexanone + [BMIM][Ac] 和 1- 辛烯 +2-hexanone + [BMIM][BF4] 的三元体系在 298.15 K、303.15 K 和 313.15 K 在 101.3 kPa 下进行了测量。计算了溶质分配系数（D）和选择性（S），以研究[EMIM][Ac]、[BMIM][Ac]和[BMIM][BF4]作为溶剂的效率。此外，本研究还考察了 D 和 S 的温度依赖性。应用 NRTL 和 UNIQUAC 模型对 LLE 实验数据进行了相关分析。

Liquid−liquid equilibrium for ternary systems of 1-Octene +2-Hexanone + ionic liquid: Phase equilibrium measurement and correlation

Liquid–liquid equilibrium (LLE) for the binary systems of 1-octene +1-ethyl-3-methylimidazolium acetate ([EMIM][Ac]), 1-octene +1-butyl-3-methylimidazolium acetate ([BMIM][Ac]), 1-octene +1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF₄]), 2-hexanone + [EMIM][Ac], and 2-hexanone + [BMIM][Ac], and the ternary systems of 1-octene +2-hexanone + [EMIM][Ac], 1-octene +2-hexanone + [BMIM][Ac], and 1-octene +2-hexanone + [BMIM][BF₄] were measured at 298.15 K, 303.15 K and 313.15 K under 101.3 kPa. The solute distribution coefficient (D) and selectivity (S) were calculated to investigate the efficiencies of [EMIM][Ac], [BMIM][Ac], and [BMIM][BF₄] as solvents. Moreover, the temperature dependencies of D and S were investigated in this study. NRTL and UNIQUAC models were applied to correlate the experimental LLE data.

期刊介绍： The Journal of Chemical Thermodynamics exists primarily for dissemination of significant new knowledge in experimental equilibrium thermodynamics and transport properties of chemical systems. The defining attributes of The Journal are the quality and relevance of the papers published. The Journal publishes work relating to gases, liquids, solids, polymers, mixtures, solutions and interfaces. Studies on systems with variability, such as biological or bio-based materials, gas hydrates, among others, will also be considered provided these are well characterized and reproducible where possible. Experimental methods should be described in sufficient detail to allow critical assessment of the accuracy claimed. Authors are encouraged to provide physical or chemical interpretations of the results. Articles can contain modelling sections providing representations of data or molecular insights into the properties or transformations studied. Theoretical papers on chemical thermodynamics using molecular theory or modelling are also considered. The Journal welcomes review articles in the field of chemical thermodynamics but prospective authors should first consult one of the Editors concerning the suitability of the proposed review. Contributions of a routine nature or reporting on uncharacterised materials are not accepted.
