Abstract (EN): In this work, experimental data of isobaric vapour–liquid equilibria for the ternary system ethanol +water + 1-hexyl-3-methylimidazolium chloride ([C6mim][Cl]) and for the corresponding binary systems containing the ionic liquid (ethanol + [C6mim][Cl],water + [C6mim][Cl]) were carried out at 101.300 kPa. VLE experimental data of binary and ternary systems were correlated using the NRTL equation. In a previous work [N. Calvar, B. Gonz´alez, E. G´omez, A. Dom´ınguez, J. Chem. Eng. Data 51 (2006) 2178–2181], the VLE of the ternary system ethanol +water + [C4mim][Cl] was determined and correlated, so we can study the influence of different ionic liquids in the behaviour of the azeotropic mixture ethanol–water.
