Extractive distillation is commonly used for the separation of azeotropic or close-boiling mixtures in the chemical industry. During the past decade, the use of ionic liquids (ILs) as entrainers has received considerable attention due to their unique advantages when applied in extractive distillation. This work is devoted to providing an easy-to-read and comprehensive review on the recent progress made by chemical engineers, focusing on the issues of predictive thermodynamic models, structure-property relations, separation mechanisms, and process simulation and optimization. This review spans from the molecular level to the industrial scale, to provide a theoretical insight into the molecular interactions between ILs and the components to be separated. Moreover, a comprehensive database on the vapor-liquid equilibria (VLE) and activity coefficients at infinite dilution concerning ILs is provided as Supporting Information. Concluding remarks are made on the unsolved scientific issues with respect to this promising special distillation technology.

“…The imidazolium-based RTILs are excellently soluble in most polar solvents 1,2,11,13,15,17,[20][21][22][23][24][25][26][27][28][29][30][31][32][38][39][40][41][42][43][44] and are relatively cheap to synthesize. Polar molecular co-solvents, such as water, methanol, acetonitrile, acetone, n-butanol, alter physical and chemical properties of the imidazolium-based RTILs drastically.…”

a b s t r a c tImidazolium-based ionic liquids are widely used in conjunction with molecular liquids for various applications. Solvation, miscibility and similar properties are of fundamental importance for successful implementation of theoretical schemes. This work reports competitive solvation of the 1,3-dimethylimidazolium cation by water and methanol. Employing molecular dynamics simulations powered by semiempirical Hamiltonian (electronic structure level of description), the local structure nearby imidazolium cation is described in terms of radial distribution functions. Although water and methanol are chemically similar, water appears systematically more successful in solvating the 1,3-dimethylimidazolium cation. This result fosters construction of future applications of the ternary ion-molecular systems.

“…The NRTL model is commonly used for the correlation of the VLE data containing ILs since it often fits the experimental data well [27][28][29][30]. In this work, the NRTL model is also adopted for the correlation of the measured VLE data.…”

Isobaric vapor–liquid equilibrium for methyl acetate+methanol system containing different ionic liquids at 101.3kPa

A B S T R A C TIsobaric vapor-liquid equilibrium (VLE) data for ternary systems of methyl acetate + methanol containing three ionic liquids (ILs) were measured at 101.3 kPa. The investigated ILs were 1-hexyl-3-methylimidazolium chloride ([HMIM][Cl]), 1-benzyl-3-methylimidazolium chloride ([BzMIM][Cl]), and 1-hexyl-3-methylimidazolium bromide ([HMIM][Br]). The results indicate that the addition of ILs can give rise to the increase of the relative volatility of methyl acetate to methanol. Besides, the more ILs, the larger the relative volatility. All the three investigated ILs can eliminate the azeotropic point of methyl acetate and methanol, and the separation effect follows the order: [HMIM][Cl] > [BzMIM][Cl] > [HMIM] [Br]. Additionally, the measured VLE data are well correlated with NRTL model.
