Isothermal vapor-liquid equilibrium data were determined by static method at 323.15 K for the binary systems {propyl vinyl ether + 1-propanol}, {propyl vinyl ether + toluene}, and {1-propanol + toluene} and also for the ternary system {propyl vinyl ether + 1-propanol + toluene}. The experimental binary and ternary vapor-liquid equilibrium data were correlated with different G(E) models such as the Margules, van Laar, Wilson, NRTL, and UNIQUAC equations. In addition, excess molar volume data are reported for the same systems at 298.15 K. The excess molar volume data were correlated with the Redlich-Kister equation for the binary systems and the Cibulka equation for the ternary system, respectively.
