Refractive indices of binary liquid mixtures of squalane with benzene, cyclohexane and hexane at 298.15 to 313.15 K

Abstract

776-780Densities, ρ, at 298.15 K and refractive indices, n, at 298.15, 303.15, 308.15 and 313.15 K have been measured for the binary liquid mixtures of squalane with benzene, cyclohexane and hexane over the whole mole fraction range. From refractive index data, the refractive index deviations, Δn, at different temperatures have been calculated and fitted to the Redlich-Kister polynomial equation to estimate the adjustable parameters and the standard deviations. Further, theoretical prediction of refractive indices of these binary liquid mixtures at 298.15 K have been made using various mixing rules. Results obtained have been discussed in terms of average percentage deviations
