Densities, Viscosities, Refractive Indices, and Surface Tensions of 4-Methyl-2-Pentanone + Ethyl Benzoate Mixtures at (283.15, 293.15, and 303.15) K

Densities ( ρ ), viscosities ( η ), refractive indices ( n D ), and surface tensions ( σ ), 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 ( Δη ), and the excess refraction ( Δ 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.
