Excess partial molar volumes and viscosity deviations of binary mixtures of n-butylacetate +1- chloroalkanes Comparison with theory

Densities ρ, dynamic viscosities η, of the binary mixture {(nbutylacetate + 1-chlorobutane, +1-chloropentane, +1- chlorohexane,+1-chloroheptane,+1-chlorooctane)} have been measured over the whole composition range at 298.15 K for the liquid region and at ambient pressure. The excess molar volumes Vm E, excess partial molar volumes E i V , limiting excess partial molar volumes E,∞ i V viscosity deviations Δη, calculated from experimental densities and viscosity. The experimental data of constitute were correlated as a function of the mole fraction by using the Redlich–Kister equation for binary mixtures. The McAllister's, Hind, and Nissan - Grunberg interaction models are used to correlate the kinematic and dynamic viscosity of binary mixtures, respectively, to determine the fitting parameters and the standard deviations. The experimental data of the constitute binaries are analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
