Popis: 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.
