Vapour pressures of propyl acetate, isobutyl acetate and 2-propanol from
0.004 to 1.6 MPa absolute pressure and VLE data for the binary systems propyl
acetate+ethanol, propyl acetate+2-propanol, isobutyl acetate+ethanol and
isobutyl acetate+2-propanol at 0.15 MPa have been determined. The
experimental VLE data were verified with the test of van Ness and the
Fredenslund criterion. The propyl acetate+ethanol or +2-propanol binary
systems have an azeotropic point at 0.15 MPa. The different versions of the
UNIFAC and ASOG group contribution models were applied.
