Isothermal (vapour + liquid) equilibria of (4-methylpentane-2-one + pyridine), (4-methylpentane-2-one + 1,4-dioxane), and (pyridine + 1,4-dioxane) have been measured at 308.65, 313.15, 318.15, and 323.15 K using the total-pressure method. The results are analysed by Barker's method with UNIQUAC, Wilson, and NRTL equations. All three models are found to represent the results satisfactorily. All mixtures show positive deviations from ideality; none forms an azeotrope. © 1989.

Isothermal (vapour + liquid) equilibria of three binary mixtures at four temperatures

The Journal of Chemical Thermodynamics

Isothermal (vapor + liquid) equilibria of (acetone + tetrahydrofuran), (tetrahydrofuran + acetonitrile), (tetrahydrofuran + 1,2-dichloroethane), and (acetonitrile + 1,2-dichloroethane) have been measured at 302.15 K using the total-pressure method. The results are analysed by Barker's method with Wilson, NRTL, and UNIQUAC equations. All three are found to represent the results satisfactorily for the four mixtures. (Tetrahydrofuran + 1,2-dichloroethane) shows negative deviations from ideality; the other three show positive deviations. (Acetonitrile + 1,2-dichloroethane) and (acetone + tetrahydrofuran) form azeotropes. © 1984.
