Vaporization enthalpies of self-associated aromatic compounds at 298.15 K: A review of existing data and the features of heat capacity correction. Part III. Polyphenols, polyanilines and aminophenols

Abstract

The experimental data on the phase transition enthalpies and heat capacities of numerous polyphenols, polyanilines and aminophenols in the condensed and ideal gas state were analyzed to obtain the reliable values at 298.15 K. For this purpose, we combined experimental data on the crystal, liquid, and ideal gas heat capacities and fusion, sublimation and vaporization enthalpies. Significant part of these data, including the ideal gas heat capacities of 16 molecules, vapor pressures and vaporization enthalpies of 1,3-diaminobenzene and 1,6-dihydroxynaphthalene, were obtained in this work. A modified approach for the estimation of the temperature dependence of vaporization enthalpies of polyphenols, polyanilines and aminophenols showing performance competitive with the experimental one was proposed based on the analysis performed.
