The excess molar volumes, VE, and viscosity deviations, Δη, were calculated from the measured density and viscosity data over the whole composition range for the ternary systems of 1,3-dioxolane (DO), dichloromethane (DM) + methyl acetate (MA), ethyl acetate (EA), propyl acetate (PA), butyl acetate (BA) and isoamyl acetate (IA) at 298.15 K. From the experimental observations the speed of sounds and refractive indices of these ternary mixtures have been measured over the entire range of composition at the same temperature. Also the isentropic compressibility, deviation in isentropic compressibility and deviation in molar refraction have been evaluated. The excess or deviation properties were found to be either negative or positive depending on the molecular interactions and the nature of liquid mixtures.
