Density and refractive index have been experimentally determined for binary liquid mixtures of n-octane + 2-hexanol, n-octane + 2-octanol, and 2-hexanol + 2-octanol at 298.15 K and atmospheric pressure, over the whole composition range. A comparative study of several relations for predicting the refractive index of a liquid has been carried out to test their validity for the above systems. The excess molar properties are calculated from the measured data and are correlated by a Redlich-Kister type equation.
