Abstract

Experimental densities, viscosities and ultrasonic velocities were measured for ternary liquid mixtures of diethylmalonate+ 1, 4-dioxane with cyclohexane and n-hexane at 308.15K and 318.15K and atmospheric pressure over the entire range of mole fractions. The calculated thermodynamic properties and some excess parameters such as VE, ΔKs,  Δɳ, ΔVF, ΔLF, ΔβΤ, were calculated and applied to Redlich − Kister polynomial equation to determine the appropriate coefficients. The deviations of the ternary mixtures from its ideal behaviour were determined and the interaction ability of the liquids in the ternary liquid mixtures was studied.
