✦ Synopsis

We have determined the excess molar enthalpies H E of binary mixtures containing an m Ž . Ž ␣ , -dichloroalkane from 1,3-dichloropropane to 1,6-dichlorohexane and a 1-alkanol 1-. pentanol, or 1-hexanol using a Calvet microcalorimeter at the temperature T s 298.15 K and normal atmospheric pressure. All mixtures exhibit endothermic behaviour for the whole composition range. The experimental values were compared with values calculated from three versions of a UNIFAC group-contribution formalism. The experimental and calculated results are discussed in terms of molecular interactions and the proximity effect.
