Abstract :Thermodynamic properties provide a deep and significant insight of the various interactions taking place multi component liquid mixtures especially in the field of petrochemical and reservoir engineering. The density, viscosity and ultrasonic velocity were measured experimentally for diethylmalonate insert ignore into journalissuearticles values(DEM); +1,4-dioxane with nitrobenzene insert ignore into journalissuearticles values(TM-1); and diethylmalonate insert ignore into journalissuearticles values(DEM); +1,4-dioxane + toluene insert ignore into journalissuearticles values(TM-2); at the temperature of 308.15K and atmospheric pressure over the entire range of mole fraction. The excess thermodynamic properties such as excess volume insert ignore into journalissuearticles values(VE);, excess adiabatic compressibility insert ignore into journalissuearticles values(ΔKs);, excess viscosity insert ignore into journalissuearticles values(Δɳ);, excess free volume insert ignore into journalissuearticles values(ΔVF);, excess free length insert ignore into journalissuearticles values(ΔLF);, excess isothermal compressibility insert ignore into journalissuearticles values(ΔβΤ);, were calculated from measured values and applied to Redlich - Kister polynomial equation to determine the appropriate coefficients. The excess or deviation properties were found to be either negative or positive depending on the molecular interactions and the nature of liquid mixtures. The deviations of the ternary mixtures from its ideal behaviour were determined in order to investigate the molecular interaction between the components of ternary liquid mixtures.
