Total pressure and excess Gibbs energy for the ternary mixture di-isopropyl ether + 1-propanol + benzene and its corresponding binary systems at 313.15 K

Total pressure measurements are reported for the ternary system ‘di-isopropyl ether + 1-propanol + benzene’ and two of the binary systems involved ‘di-isopropyl ether + 1-propanol’ and ‘1-propanol + benzene’ at 313.15 K. Data reduction by Barkerʹs method provides correlations for GE using the Margules equation for the binary systems and the Wohl expansion for the ternary system. Wilson, NRTL and UNIQUAC models have been applied successfully to both the binary and the ternary systems.
