Abstract

The objective of this
research work is to determine the effect of ionic liquids on the vapor liquid
equilibrium behaviour of methanol and ethyl acetate binary system at
atmospheric pressure. The ionic liquids used in the experiments are:
1-ethyl-3-methylimidazolium Chloride [EMIM][Cl], 1-ethyl-1-methylpyrrolidinium
Bromide [EMPyrr][Br]. VLE experiments were conducted with Othmer still experimental
setup and the VLE data sets were tested for thermodynamic consistency.  Experimental results average deviations were
within the experimental toleration limits and satisfied the Gibbs-Duhem
equation.  The results showed that the
addition of ionic liquids (ILs) caused salting-out of methanol from the system.  For the same concentrations of the ionic
liquids, [EMIM][Cl] is observed to be more effective than the [EMPyrr][Br] in
breaking the azeotropes and in increasing the salting effect.  For the 15% concentration of [EMPyrr][Br] the
azeotrope was completely disappeared.
