Experimental values of density, viscosity, and refractive index are presented for the binary mixtures of cyclohexane with hexane, heptane, octane, nonane, and decane at (298.15, 303.15, and 308.15) K over the entire mole fraction range of the mixture components at atmospheric pressure. From these data, excess molar volume, deviations in viscosity, and molar refractivity of the mixtures have been calculated. These quantities are further fitted to the Redlich−Kister relation to estimate the binary interaction parameters and standard errors. The results of excess molar volume and deviations in viscosity are comparable with the available published results at 298.15 K. The sign and magnitude of the calculated excess quantities have been discussed in terms of the nature of the solvent−solvent interactions in binary mixtures.
