Abstract: | 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 0.1 MPa for eight binary mixtures of 1-ethyl-3-methylimidazolium chloride ([C(2)mim][Cl]), 1-butyl-3-methylimidazolium chloride ([C(4)mim][Cl]), 1-hexyl-3-methylimidazolium chloride ([C(6)mim][Cl]), and choline chloride ([N-111(2OH)[Cl]) with water and ethanol. The experimental data here measured were correlated with the NRTL model. (C) 2013 Elsevier B.V. All rights reserved. |
