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.

“…In ref LLE data for the ternary systems containing acidic IL–ethyl acetate–ethanol or acetic acid are reported, and the influence of the alkyl chain length on the LLE were studied at 313.2 K. In this work authors used several ILs: 1-methylimidazolium hydrogen sulfate ([hmim][HSO4]), 1-ethyl-3-methylimidazolium hydrogen sulfate ([emim][HSO4]), and 1-butyl-3-methylimidazolium hydrogen sulfate ([bmim][HSO 4 ]). In the ref the data on LLE for ethyl acetate–ethanol–1-ethyl-3-methylimidazolium acetate at 288.15, 299.15, and 308.15 K is presented. The ternary LLE for four systems alcohol ( n -propanol or n -butanol)–ester–1-ethyl-3-methylimidazolium hydrogen sulfate [emim][HSO 4 ] were studied at 313.2 K …”

Study of Deep Eutectic Solvent on the Base Choline Chloride as Entrainer for the Separation Alcohol–Ester Systems

et al. 2018

Choline chloride-based deep eutectic solvent (DES) was tested for the separation of azeotropic mixtures of ethanol−ethyl acetate, n-propanol−n-propyl acetate and nbutanol−n-butyl acetate via liquid−liquid extraction. The mixture of choline chloride with malonic acid with a molar ratio of 1:1 was used. Extraction experiments were conducted with the ternary mixture ethanol−ethyl acetate−DES at temperatures 293.15, 303.15, and 313.15 K and with ternary mixtures npropanol−n-propyl acetate−DES and n-butanol−n-butyl acetate−DES at 293.15, 303.15, 313.15, and 323.15 K. Liquid− liquid tie-lines for studied systems were determined. The extraction performance of DES was characterized with solute distribution coefficients and values of selectively respectively to alcohol. The influence of the alkyl chain length of the alcohol and ester on the phase equilibria was investigated. Experimental data were fitted using the nonrandom two liquids model.

“…Orchilles et al 18,19 20 They also studied the vapor liquid equilibrium of ethyl acetate−ethanol using 1-alkyl-3-methylimdazolium tetrafluoroborate at 101.32 kPa. 21 Cai et al 22 24 In the present work, methyl acetate−methanol and ethyl acetate− ethanol systems were chosen since these are important solvents in industry. These nonaqueous azeotropic mixtures are used in the poly vinyl alcohol manufacturing process 22,23 and in the process of esertification, 24 among others.…”

The separation of the nonaqueous azeotropic systems methyl acetate−methanol and ethyl acetate−ethanol was investigated with 13 cations and 27 anions as entrainers to identify suitable ionic liquids using the COSMO-RS model. It is observed that the cations best suited are imidazolium > pyridinium > methyl pyrrolidinium > octyl quinolinium. The lengthening of the alkyl chain of cations was also studied as well as whether the shorter the alkyl chain, the better is the separation. It was also noticed that the efficacy of the anions is in the order
