Densities, viscosities, refractive indices, and surface tensions of dimethyl sulfoxide plus butyl acetate mixtures at (293.15, 303.15, and 313.15) K

Densities (rho), viscosities (eta), refractive indices (n(D)), and surface tensions (sigma) have been measured for dimethyl sulfoxide + butyl acetate mixtures, over the entire composition range at (293.15, 303.15, and 313.15) K. The excess volumes (V-E), the viscosity deviations (Delta eta), and the deviations in refraction (Delta R) were calculated from these experimental data. All the properties have negative values. The results have been fitted to the Redlich-Kister type polynomial relation, and the corresponding parameters have been derived. The results are discussed in terms of molecular interactions.
