摘要
Isobaric vapor-liquid equilibrium data for the system acetone (1) + methanol (2) + zinc chloride (3) at constant salt molalities have been measured with the help of a modified Scott ebulliometer at 66.66 and 101.33 kPa. The measured data were correlated using the electrolyte UNIQUAC (Sander et al., 1986) and the LIQUAC (Li et al., 1994) model. A comparison of the correlations with the experimental data shows superior results for the LIQUAC model.
