Density, Refractive Index, Viscosity, and Speed of Sound in Binary Mixtures of Cyclohexanone with Hexane, Heptane, Octane, Nonane, Decane, Dodecane, and 2,2,4-Trimethylpentane

Experimental results of density, refractive index, and viscosity at 298.15, 303.15, and 308.15 K and the speed of sound at 298.15 K are presented for the binary mixtures of cyclohexanone with n-alkanes (C6−C12) or 2,2,4-trimethylpentane over the entire range of mixture composition scale. From these data, excess molar volume VE, deviations in molar refraction ΔR, viscosity Δη, speed of sound Δu, and isentropic compressibility ΔkS have been calculated. These results are further fit to the Redlich and Kister (1948) polynomial equation to derive the binary coefficients and standard deviations between the calculated and the fit parameters. Furthermore, these results are used to study the nature of intermolecular interactions between the mixing components. All the properties have shown a systematic dependence on the chain length of alkanes.
