ABSTRACT

Densities and viscosities for ternary mixtures of diethylketone + 2-butanol + ethylchloroacetate, and related binary mixtures have been reported as a function of mole fraction at temperatures (298.15 K, 308.15 K and 318.15 K) for binary and 298.15 K for ternary mixtures. Excess molar volumes VEm , viscosity deviations , and excess thermal expansion coefficients ^2E, were calculated from the experimental data. Redlich Kister and Cibulka equations were used to correlation of calculated data for binary and ternary mixtures, respectively. The experimental results of VEm are positive for the mixtures of (diethylketone + 2- butanol) and (2-butanol + ethylchloroacetate) and negative for (diethylketone + ethylchloroacetate) over the whole composition range. The values of are negative for three binary mixtures. The results were analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
