ABSTRACT

Densities, viscosities and refractive indices of the binary mixtures of n-butyl acetate + 1- chlorobutane, + 1-chloropentane, + 1-chlorohexane, + 1-chloroheptane, and + 1-chlorooctane were measured at 298.15 K for the liquid region and at ambient pressure for the whole composition range. The excess molar volumes were calculated from experimental densities. Viscosity deviations and the refractive index deviations AnD from the mole fraction average, for the mixtures were derived from the experimental data. The binary data of , and AnD were correlated as a function of the mole fraction by using the Redlich-Kister type function to determine the fitting parameters and the standard deviations. McAllister's three-body interaction, Hind and Nissan-Gruenberg models are used for correlating the kinematic viscosity of binary mixtures. The experimental data of binaries are analyzed to discuss the nature and strength of intermolecular interactions in these mixtures.
