Resumen
Density, speed of sound and viscosity for the ternary system formed by toluene, benzene and methyl acetate and their corresponding binaries were measured at atmospheric pressure in the temperature range of 288.15 K to 318.15 K, every 5 K. Experimental data were used to calculate derived properties: excess molar volume, isentropic compressibility, isentropic compressibility deviation, viscosity deviation and excess free energy of activation for viscous flow. These magnitudes were fitted to different equations available in the literature. In addition, geometrical models have been used to predict ternary magnitudes. Predictions of viscosities for the ternary system were performed by group contribution models. Molecular interactions among the components of the mixtures were inferred from the sign of the excess and deviation properties.
