The speed of sound in binary liquid mixtures of organic solvents with sunflower oil was measured over the entire range of concentrations at 298.15 K. The solvents considered were: n-hexane, n-heptane, n-octane, n-nonane, ethanol, 1-propanol, 2-propanol, 1-butanol, ethyl acetate, propyl acetate, isopropyl acetate, butyl acetate, and vinyl acetate. The speed of sound data were used to calculate isentropic compressibilities and excess isentropic compressibilities. The excess isentropic compressibilities vs. concentrations were correlated using Redlich-Kister polynomials. Speed of sound determinations in the mixtures were predicted using two mixing rules proposed in the literature, and values were compared with experimental data. In all cases, SD between predicted and experimental data were less than 3.5%.
