Solid-liquid equilibrium temperatures for binary mixtures of long-chain 1-alkanols (1-dodecanol, 1-tetradecanol, 1-hexadecanol, 1-octadecanol and 1-icosanol) and benzene or toluene have been measured by a dynamic method between 276 K and the melting point of the alcohol. These data are used, taking into consideration the two solid-solid first-order transitions observed in the 1-alkanols, to characterize in terms of DISQUAC the hydroxyl-aromatic interactions present in the investigated mixtures. The relative standard deviations for the equilibrium temperatures are less than 0.01 for most of the systems.
