Measurement and prediction of vapor pressure in binary systems containing the ionic liquid [EMIM][DCA]

The vapor-liquid equilibrium (VLE) data for water/methanol/ethanol +1-ethyl-3-methylimidazolium dicyanamide ([EMIM][DCA]) binary mixtures were measured by a saturated vapor pressure device at different temperatures. The experimental results showed that the existence of ionic liquid (IL) has a significant effect on the VLE data for all the investigated systems. The thermodynamic model (i.e., modified UNIFAC model) for quantitative prediction has...
