Isothermal vapor-liquid equilibrium (VLE) data at 323.15 K are reported for the binary systems of propyl vinyl ether (PVE) + ethanol, ethanol + isooctane, and PVE + isooctane and also for ternary system of PVE + ethanol + isooctane by using headspace gas chromatography. For the computation of VLE, vapor pressure of PVE was determined and fitted to the Antoine equation. The experimental binary and ternary VLE data were correlated with different G(E) models. Additionally the new excess volume data are reported for the same binary systems at 293.15 K and correlated with the Redlich-Kister polynomial. Ternary V-E data are also calculated with correlated parameters by the Radojkovic equation.
