“…The reliability of our apparatus has been validated by the VLE data of methyl acetate + methanol binary system at 101.3 kPa in our previous study [20]. Tables 3-5, where x 3 represents the mole fraction of ILs in the liquid phase, T is the equilibrium temperature, x 1 represents the mole fraction of methyl acetate in the liquid phase containing ILs, x 0 1 refers to the mole fraction of methyl acetate in the liquid phase expressed on an IL-free basis, y 1 is the mole fraction of methyl acetate in the vapor phase.…”

“…As is well known, conventional distillations are not able to purify binary liquid mixtures beyond the concentration of this azeotropic point. Nonetheless, distillation of mixtures that present an azeotropic point can be improved by using a separating agent, sometimes called an entrainer (Kiss & Suszwalak, 2012;Matsuda et al, 2011;Bastos et al, 2015;Zhang et al, 2015). The entrainer is added in order to change the volatility of the components, and depending on its effects on the mixture, it leads mainly to two different distillations: azeotropic or extractive distillation.…”

“…In addition, the third component added in extractive distillations is often safer than the organic solvents commonly used in azeotropic distillation; this is the case, for example, of saline extractive distillations, where the entrainer is a salt, which presents very low toxicity and flammability. Although not as safe as inorganic salts as a consequence of a higher toxicity, the use of ionic liquids has recently become an interesting alternative as entrainer in SED because of their recognized advantages: in addition to their low vapor pressure, which allows an efficient recovery, ionic liquids are less corrosive and have higher solubility than inorganic salts (Bastos et al, 2015;Calvar et al, 2007;Pereiro et al, 2012;Vicent Orchillés et al, 2008;Vicent Orchillés et al, 2011, Zhang et al, 2015.…”
