Abstract (EN): In this work, experimental data of isobaric vapor-liquid equilibria (VLE) for the ternary system ethanol + water + 1-ethyl-3-methylimidazolium ethylsulfate (EMISE) and for the corresponding binary systems containing the ionic liquid (ethanol + EMISE, water + EMISE) were carried out at 101.3 kPa. VLE data of binary systems were correlated using the e-NRTL and NRTL equations. With the obtained parameters, we can predict the behavior of the ternary system. In addition, the ternary system was correlated using the NRTL equation. A study of the evolution of the ethanol + water azeotrope composition with different amounts of ionic liquid was made. © 2008 American Chemical Society.
