Vapor-liquid equilibrium at 101.32 kPa has been measured for the binary systems formed by ethyl ethanoate, propanoate, and butanoate with propan-2-ol and butan-2-ol in an equilibrium still with circulation of both the vapor and liquid phases. The data were correlated by several available equations, and the parameters are reported for each of mixtures studied. Azeotropes were found in the mixtures ethyl ethanoate or propanoate + propan-2-ol and ethyl propanoate + butan-2-ol. Satisfactory results are obtained for the prediction of activity coefficients and the equilibrium compositions with the UNIFAC modified model. The densities for the same mixtures at 298.15 K are also reported.
