Isobaric molar heat capacities of the mixture (p-cymene + ethanol) at several temperatures and atmospheric pressure
Resumen: Experimental isobaric molar heat capacities at atmospheric pressure have been determined every 10 K for the mixture p-cymene (1) + ethanol (2) in the temperature interval (298.6–328.4) K over the whole composition range with a Calvet type calorimeter. Densities, necessary for calculating heat capacities, have been also measured in the same conditions. Excess molar volumes have been calculated from densities. Excess molar heat capacities have been calculated from the molar heat capacities, their values being positive and increasing as the temperature rises. Excess properties are discussed in terms of intermolecular interactions. The solvation model COSMO-RS has been applied to predict the excess molar heat capacities. The model predicts fairly well the values of the excess heat capacities.
