Excess Molar Enthalpies and Excess Molar Volumes of Binary Systems 1-Chlorohexane + 1-Alkanol (from 1-Butanol to 1-Octanol) at 298.15 K

摘要

Excess molar enthalpies H_m~E and excess molar volumes V_m~E have been measured at 298.15 and normal atmospheric pressure for the binary mixtures 1-chlorohexane + 1-alkanol (from 1-butanol to 1-octanol) using a Calvet microcalorimeter and a vibrating tube dnesimeter, respectively. Teh 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 predictions of UNIFAC group-contribution models considered by Dang and Tassios (Dang, 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.
