“…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.…”
