Abstract
Densities, \(\rho \), viscosities, \(\eta \), speeds of sound, \(u\), and refractive indices, \(n_\mathrm{D} \), of binary liquid mixtures of 2-ethyl-1-hexanol with benzene, chlorobenzene, and bromobenzene have been measured over the entire range of composition at 298.15 K, 303.15 K, and 308.15 K and at atmospheric pressure. From the experimental data of the density, speed of sound, viscosity, and refractive index, the values of the excess molar volume, \(V^\mathrm{E}\), isentropic compressibility, \({\kappa _{S}}\), and deviations in molar refraction, \(\Delta R\), have been calculated. The viscosity data have been correlated using McAllister’s three-body interaction model at different temperatures. The calculated excess and deviation functions have been analyzed in terms of molecular interactions and structural effects.
