Densities, Viscosities, and Refractive Indices of Mixtures of Hexane with Cyclohexane, Decane, Hexadecane, and Squalane at 298.15 K

Densities, ρ, viscosities, η, and refractive indices, nD, have been measured as a function of composition for binary mixtures of cyclohexane, decane, hexadecane, and squalane with hexane at 298.15K and atmospheric pressure. From these measurements the excess molar volumes, V E m , viscosity deviations, δη, and the change in refractive indices on mixing, ΔnD, were calculated. These results were fitted to Redlick–Kister polynomial equations to estimate the binary coefficients and standard errors. The effects of size and shape of the components on excess properties have been discussed.
