Abstract
Phase equilibria were studied in the systems methanol-methyl ethyl ketone, ethanol-methyl ethyl ketone, methyl ethyl ketone-2-propanol, methyl acetate-1-propanol, and methyl acetate-2-propanol under isothermal conditions. Heat of mixing data were obtained for these systems. The Wilson and NRTL equations were able to represent simultaneously these two kinds of thermodynamic quantities under the assumption that their parameters were temperature-dependent.
