Binary liquid mixes of 1-butanol, 1-pentanol, 1-hexanol, and 1-heptanol with hexadecane and heptadecane have had their densities and refractive indices experimentally determined at 298.15, 308.15, and 318.15 K. To determine whether the Lorentz-Lorenz (L-L), Weiner-Heller (W-H), and Gladstone-Dale (G-D) relations for predicting the refractive index of a liquid are valid for the eight binaries over the entire mole fraction range of hexadecane and heptadecane at the three temperatures, a comparative study of these relationships has been conducted. The average percentage deviation has been used to compare different mixing rules. Comparatively speaking, the Weiner and Gladstone-Dale relations perform better than the Lorentz-Lorenz and Heller relations.
