Densities,viscosities and speed of sound of n-butyl acetate with toulene at 303.15, 308.15 and 313.15 K: Comparative study on viscosity models

Abstract

The densities, viscosities and speeds of sound of n-butyl acetate with toluene at different temperatures have been measured experimentally. The excess molar volumes, deviations in viscosities, excess Gibbs free energies, deviations in speeds of sound and isentropic compressibilities have been calculated across the mole compositions. The compositional variation of excess and deviation functions has been expressed in terms of the Redlich-Kister equation. The viscosity data are correlated with some of the semi-empirical viscosity models and the results are compared with the experimental findings.
