Isothermal vapor—liquid equilibrium of ternary mixtures formed by 1-propanol, acetonitrile and benzene

Abstract

Vapor—liquid equilibrium data are presented for the ternary system 1-propanol-acetonitrile-benzene, at 45°C. The experimental vapor—liquid equilibrium results of the three constituent binary systems are well reproduced with the UNIQUAC associated-solution model and the ternary results are compared with those calculated from the model with binary parameters alone. Ternary prediction of liquid—liquid equilibria is given for the 1-propanol-acetonitrile- n-hexane and 1-propanol—acetonitrile- n-heptane systems at 25°C.
