Abstract: Isobaric vapor-liquid equilibrium data were measured at 74.66, 101.32 and 127.99 kPa for binary mixtures composed of methyl ethanoate or methyl propanoate and propan-2-ol using a dynamic method. In thermodynamic calcutions using the data, the vapor phase was considered to be non-ideal, and all the systems studied exhibit positive deviations from ideal solution behavior. At 74.66 kPa, the binary system (x1 methyl propanoate + x2 propan-2-ol) presents an azeotrope at x1 = 0.666, T = 340.47 K; as pressure increased, azeotrope concentration decreased quasi-regularly towards regions richer in propan-2-ol. After reduction of the data by fitting with a suitable equation and verification of thermodynamic consistency, various group-contribution models were applied to estimate the isobaric VLE data. The mean error in prediction of the activity coefficients for each system in no case exceeded 7%.
