Abstract

Excess molar Gibbs free energy of mixing for 1-butanol or 2-butanol or 2-methylpropan-1-ol or 2-methylpropan-2-ol + cyclohexane over the entire range of composition at 308.15 K have been calculated by Barker method from vapour pressure data measured by a static method. The free energy data have been analysed in terms of Mecke-Kempter type of association model with a Flory contribution term using two interaction parameters. The predicted values agree reasonably well with the corresponding experimental values.
