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.

Isothermal (vapor+liquid) equilibria of four binary mixtures

The Journal of Chemical Thermodynamics

Isothermal (vapor + liquid) equilibria of (4-methylpentan-2-one + pyridine + 1,4-dioxane) have been measured at (308.65, 313.15, 318.15, and 323.15) K using the total-pressure method. The pressure was also predicted using the Wilson model with parameters determined from binary (vapor + liquid) equilibria. The predicted vapor pressures agree satisfactorily with the measured values at all four temperatures. © 1990.

Isothermal (vapor + liquid) equilibria of (4-methylpentan-2-one + pyridine + 1,4-dioxane) at four temperatures

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.
