Viscosities and densities of three binary liquid mixtures, benzeneþmethylacetate, benzeneþmethyl propanoate and benzeneþmethyl butanoate, have been measured at 283.15, 298.15 and 313.15 K, and atmospheric pressure. From experimental data, viscosity deviation, excess energy of activation for viscous flow, and excess molar volume were calculated and satisfactorily correlated with Redlich and Kister equation. Empirical and semiempirical equations and the predicted group-contribution method, universal automatic computer, were applied
