摘要：

Excess molar enthalpies HEmand excess molar volumes VEm at 25°Cand normal atmospheric pressure for the binary mixtures 1-chloropentane + 1-alkanol(from 1-butanol to 1-octanol) have been determined using a Calvet microcalorimeterand from density measurements using a vibrating tube densimeter. The HEm valuesfor all the mixtures are positive and VEm values are positive or negative dependingon the mole fraction of the chloroalkane. Experimental HEm results are comparedwith the predictions of UNIFAC group-contribution models proposed by Dang andTassios and by Larsen et al., and are discussed in terms of molecular interactions.
