Densities, viscosities, and refractive indices of binary liquid mixtures of hexane, decane, hexadecane, and squalane with benzene at 298.15 K

Densities, rho, viscosities, eta, and refractive indices, n(D), for binary mixtures of hexane, decane, hexadecane, and squalane with benzene were measured over the whole composition range at 298.15 K and atmospheric pressure. The excess molar volumes, V-m(E), and viscosity deviations, delta eta, were calculated from experimental measurements. These result were further fitted to the Redlich-Kister equation to estimate the binary coefficients and standard errors. The effects of chain length and branching of alkanes on V-m(E) and delta eta values have been discussed.
