Excess molar enthalpies and excess molar volumes of binary systems 1-chlorohexane+1-alkanol (from 1-butanol to 1-octanol) at 298.15 K

Excess molar enthalpies H-m(E) and excess molar volumes V-m(E) have been me asured at 298.15 K and normal atmospheric pressure for the binary mixtures 1-chlorohexane + 1-alkanol (from 1-butanol to 1-octanol) using a Calvet mic rocalorimeter and a vibrating tube densimeter, respectively. The values of H-m(E) and V-m(E) for all of the mixtures are positive over the whole range of composition. Experimental H-m(E) results are compared with the predicti ons of UNIFAC group-contribution models considered by Dang and Tassios (Dan g, D.; Tassios,P. Ind. Eng. Chem. Process Des. Dev. 1986, 25, 22-31) and by Larsen et al. (Larsen, L.; Rasmussen, P.; Fredenslund, A. Ind. Eng. Chem. Res. 1987, 26, 2274-2286) and discussed in terms of molecular interactions.
