Abstract: The vapour pressures of n-propyl acetate, iso-butyl acetate and 2-propanol from 0.004 to 1.6 MPa absolute pressure and vapour--liquid equilibria (VLE) data for the binary systems n-propyl acetate+ethanol, n-propyl acetate+2-propanol, iso-butyl acetate+ethanol and iso-butyl acetate+2-propanol at 0.15 MPa were determined. The experimental VLE data were verified with the van Ness Test and the Fredenslund Criterion. The n-propyl acetate+ethanol and +2-propanol binary systems have an azeotropic point at 0.15 MPa. Different versions of the universal quasichemical functional group activity coefficients and analytical solutions of groups contribution models were applied.
