The saturation pressures of 1-propanol at (311 to 353) K were measured by the ebulliometric method. The vapor-liquid equilibrium (VLE), simultaneous measurements of pressure, temperature, and composition of liquid and vapor phases (x, y, p, T), was measured by an ebulliometric method for the system benzene + 2-methylpentane at (313.14, 323.14, and 333.13) K and for the system allyl alcohol + 1-propanol at (313.15, 333.15, and 353.15) K. The experimental vapor pressures were correlated with the Antoine and association + equation of state (AEOS) equations, and VLE was correlated with equations representing the activity coefficient and with the AEOS equation of state.
