ABSTRACT
Isobaric vapor-liquid equilibrium at 101.3 kPa has been measured for the systems 1-pentanol + cyclohexane and 1-pentanol + n-hexane, at low alcohol mole fractions. These data were satisfactorily correlated with Wilson, NRTL, and UNIQUAC activity coefficient models to obtain the binary interaction parameters of both mixtures. With these parameters, an accurate knowledge of vapor-liquid equilibrium for both mixtures can be reached in a range of 1-pentanol mole fractions less than 0.1.
