ABSTRACT

Refractive indices and surface tensions for binary mixtures of six 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. Refractive indices were measured using a digital Abbe-type refractometer. Surface tensions were determined using the Wilhelmy-plate method. Deviations in the refractive index centsnD and deviations in the surface tension centso from volume fraction average for the binary mixtures were derived from experimental data. The binary data of centsnD and centso were correlated as a function of mole fraction using the Redlich-Kister equation.
