Popis: Densities (ρ), speeds of sound (u), and isentropic compressibilities (kS) of binary mixtures of dimethyl sulfoxide (DMSO) with water, methanol, ethanol, 1-propanol, 2-propanol, acetone and cyclohexanone have been measured over the entire composition range at 293.15 and 313.15 K. The excess molar volumes (VE), the deviations in speed of sound (uE) and the deviations in isentropic compressibility (kSE) have been determined. The VE, uE and kSE values were fitted by the Redlich-Kister polynomial equation and the Ak coefficients as well as the standard deviations (d) between the calculated and experimental values have been derived. The results obtained are discussed from the viewpoint of the existence of interactions between the components of the binary mixtures.
