Abstract
Densities and viscosities for six binary mixtures formed by the flavor esters (ethyl acetoacetate, ethyl isovalerate, methyl benzoate, benzyl acetate, ethyl salicylate, and benzyl propionate) with ethanol over the whole composition range were measured at four different temperatures (288.15, 298.15, 308.15, and 318.15) K and atmospheric pressure. Densities were determined using a vibrating-tube density meter. Viscosities were measured with an automatic Ubbelohde capillary viscometer. Excess molar volumes (V E) and deviations in the viscosity from mole fraction average (Δη) for the binary mixtures were derived from experimental data. The binary data of V E and Δη were correlated as function of the mole fraction by using the Redlich−Kister equation. Furthermore, McAllister's multi-body interaction models are used to correlate the binary kinematic viscosities.
