Abstract (EN): A study on the isobaric vapor-liquid equilibria of the ternary system containing the ionic liquid 1-ethyl- 3-methylpyridinium ethylsulfate (EMpyESO4) and the azeotropic mixture ethanol + water is presented in this work. Experimental isobaric vapor-liquid equilibrium of the ternary system ethanol + water + EMpyESO4 was determined at 101.3 kPa, together with the vapor-liquid equilibria of the binary systems ethanol + EMpyESO4 and water + EMpyESO4. The experimental data obtained from the binary vapor-liquid equilibria were correlated using the NRTL and e-NRTL equations. The NRTL equation was also used to correlate the experimental vapor-liquid equilibrium of the ternary system. With the parameters obtained from these correlations, the evolution of the azeotrope ethanol + water with different amounts of ionic liquid can be studied. The results obtained were compared with the isobaric vapor-liquid equilibria data of the system containing this azeotropic mixture with the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate.
