Over the last decade ionic liquids appeared as potential entrainers for extractive distillation processes. However experimental vapor-liquid equilibrium data for ionic liquid containing systems is still scarce since most conventional equilibrium cells are not adequate for these systems. To overcome that limitation a new isobaric microebulliometer, operating at pressures ranging from 0.05 to 0.1. MPa and requiring a sample volume lower than 8. mL was developed and validated in this work.The new apparatus was used to determine isobaric VLE data at pressures of 0.05, 0.07 and 0.1MPa for eight binary mixtures of 1-ethyl-3-methylimidazolium chloride ([C2mim][Cl]), 1-butyl-3-methylimidazolium chloride ([C4mim][Cl]), 1-hexyl-3-methylimidazolium chloride ([C6mim][Cl]), and choline chloride ([N111(2OH)][Cl]) with water and ethanol. The experimental data here measured were correlated with the NRTL model.
