Abstract

Excess molar volumes (Vm E ) of binary mixtures of 1-propanol or 2-propanol (1) + cyclohexane or n-hexane (2) were measured with V-shaped dilatometer at 303.15 K. The Vm E data for these mixtures varied as: 2-propanol > 1-propanol and were higher for cyclohexane than n-hexane for both propanol systems. The experimental data were correlated with Redlich-Kister polynomial. The Vm E data were interpreted qualitatively as well as quantitatively in terms of Flory- Treszczanowicz-Benson model and Prigogine-Flory-Patterson theory. Both models correctly described the sign and shape of Vm E vs x1 curves. The values calculated by both the models agree well with the experimental data.
