ABSTRACT

In this paper, we report the new experimental values of densities, speeds of sound, and refractive indices for four binary mixtures: {methyl isobutyl ketone (MIBK) + dimethyl sulfoxide (DMSO) or acetone or acetonitrile, or cyclohexane} over the entire composition range and in the temperatures range (293.15 313.15) K at 10 K intervals and pressure p = 0.1 MPa. From these experimental results, thermodynamics properties: excess molar volume, isentropic compressibility, deviation in isentropic compressibility and deviation in refractive indices were calculated. Excess molar volume, deviation in isentropic compressibility and deviation in refractive indices have been correlated using the Redlich Kister equation. From the obtained results, a discussion was carried out in terms of nature of intermolecular interactions and structure factors in these binary mixtures.
