The solution calorimetry approach for determination of the fusion enthalpy at 298.15 K of aromatic compounds not capable of self-association was extended to those forming intermolecular hydrogen bonds. Two groups of such compounds, namely phenol and aniline derivatives, were investigated. From the solution enthalpies at 298.15 K of phenols in anisole and aromatic amines in aniline the fusion enthalpies at 298.15 K can be derived. Validity of the solution calorimetry approach was checked using differential scanning calorimetry and fast scanning calorimetry. The solution enthalpies of 12 compounds in anisole and aniline at 298.15 K and the fusion enthalpies at the melting temperature of 9 compounds were measured. Resorcinol, 1,6-dihydroxynaphthalene, and 1,3-diaminobenzene were additionally studied using fast scanning calorimetry. The molar heat capacities of crystalline 1,6-dihydroxynaphthalene and liquid 1,3-diaminobenzene were measured by conventional DSC in the wide temperature range. (C) 2019 Elsevier Ltd.
