From the experimental data of densities and speeds of sound, the isentropic compressibilities and the excess isentropic compressibilities were calculated and from the experimental data of refractive indices, the deviation in refractive indices and the molar refractions have been computed. These excess properties of the binary mixtures were correlated by the Redlich-Kister type polynomials using a robust regression along a gnostic influence function. Speeds of sound and isentropic compressibilities have been compared with calculated values from Jacobson free length theory (FLT), Nomoto’s relation (NR), Zhang Junjie’s relation (JR), Van Deal’s ideal mixing relation (IMR) and Impedance dependence relation. The ability of different theoretical (n, ρ) mixing rules (Lorentz-Lorenz, Gladstone-Dale, Arago-Biot, Edwards and Eykman) to predict the refractive indices was evaluated. The experimental and calculated results are discussed in terms of molecular interactions and structural effects between components of mixtures.
