ABSTRACT

The excess molar volumes, Vm E , and viscosity deviations, Ac, were calculated from the measured density and viscosity data over the whole composition range for the ternary systems of cyclohexane (CHX) + cyclohexanone (CHXN) + methyl acetate (MA), ethyl acetate (EA), and propyl acetate (PA) and the constituent binary mixtures of cyclohexane or cyclohexanone + methyl acetate, ethyl acetate, propyl acetate, and cyclohexane or cyclohexanone at 298.15 K under atmospheric pressure. The excess or deviation properties of the binary and ternary systems were fitted to Redlich-Kister and Cibulka equations, respectively. The excess or deviation properties were found to be either negative or positive depending on the molecular interactions and the nature of liquid mixtures.
