摘要
Densities (rho), viscosities (eta), refractive indices (n(D)), and surface tensions (sigma), for 4-methyl-2-pentanone + ethyl benzoate mixtures, have been measured over the whole composition range at (283.15, 293.15, and 303.15) K. The excess volumes (V-E), the viscosity deviations (Delta eta), and the excess refraction (Delta R) were calculated and show negative values. The results were fitted to a Redlich-Kister type polynomial relation, and the corresponding parameters have been derived. The results are discussed in terms of molecular interactions.
