ABSTRACT

Isobaric vapour liquid equilibrium measurements for mixtures containing 1,4-dioxane and cyclopentane, cyclohexane or benzene at the pressures of 40.0, 66.6 and 101.3 kPa are reported. The experimental data were tested for thermodynamic consistency, the calculated activity coefficients have been correlated using Wilson, NRTL and UNIQUAC equations. The system 1,4-dioxane with cyclohexane shows minimum temperature azeotropes. Using our VLE results UNIFAC and predictive Soave Redlich Kwong methods were tested.
