摘要

Densities, viscosities and speeds of sound for the binary systems of butyl propionate with cyclopentanone, 3-pentanone, cyclohexanone and acetophenone have been determined as a function of composition at (303.15 and 313.15) K and atmospheric pressure. The excess volume ( V E ), excess Gibbs free energy of activation of viscous flow (Δ G *E ), deviation in speeds of sound (Δ u ), isentropic compressibility ( K S ), deviation in isentropic compressibility (Δ K S ), and intermolecular free length ( L f ) were derived from the experimental data. These binary data were correlated as a function of the mole fraction by using the Redlich- Kister Polynomial equation to determine the fitting parameters and the standard deviations.
