Excess molar volumes, viscosity deviations and excess thermal expansion coefficients for binary and ternary mixtures consist of diethylketone + 2-butanol + ethylchloroacetate at (298.15, 308.15 and 318.15) K

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 (298.15K, 308.15K and 318.15K) for binary and 298.15K for ternary mixtures. Excess molar volumes VmE, viscosity deviations Δη, and excess thermal expansion coefficients αE, 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 VmE 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 Δη are negative for three binary mixtures. The results were analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
