Densities, speeds of sound, and refractive indices of the ternary mixtures (toluene plus methyl acetate plus butyl acetate) and (toluene plus methyl acetate plus methyl heptanoate) at 298.15 K
Density, p. speed of sound. it, and refractive index. n(D), at 298.15 K and atmospheric pressure have been measured over the entire composition range for (toluene + methyl acetate + butyl acetate) and (toluene + methyl acetate + methyl heptanoate) systems. Excess molar volumes, V-E, isentropic compressibility, K-s, isentropic compressibility deviations, Delta K-s, and changes of refractive index on mixing, Delta n(D), for the above systems, have been calculated from experimental data and fitted to Cibulka, Singh et al., and Nagata and Sakura equations, standard deviations from the regression lines are shown. Geometrical solution models, Tsao and Smith, Kholer, Jacob and Fitzner, Rastogi et al. were also applied to predict ternary properties from binary contributions. (c) 2006 Elsevier Ltd.
