Abstract: Density (?) and viscosity (?) for ternary liquid mixtures of ethanol + 1,2 propanediol + cyclohexanone were measured at 308.15 and 318.15K over the entire range of composition. From the measured data, Excess volume (VE ), Deviation in viscosity (??) and excess Gibbs free energy of activation of viscous flow (?G *E) were calculated. The results were fitted with Redlich-kister’s type polynomial equation and standard deviation between calculated and experimental excess parameter have been determined. Further, Heat of mixing and FT-IR spectrum are studied at equimolar concentration. The results provide information on the interaction of molecules in the pure liquids as well as in the ternary liquid mixtures.

Keywords: Excess volume, Deviation in viscosity, Excess Gibbs free energy of activation of viscous flow, Heat of mixing, FT-IR spectra.
