This method was checked by calculation of sublimation enthalpies of 12 substituted benzamides, containing −CH3, −OCH3, −F, −OH, −NH2 and −NO2 substituents, as well as m- and p-pyridinecarboxamides, which were compared to literature values. Sublimation enthalpies of 3-aminobenzamide, 3- and 4-nitrobenzamides at 298.15 K were determined by solution calorimetry approach and amounted to 123.9 and 124.5 kJ·mol−1, respectively. This method showed good congruence with the results of direct experiment, as well as with solution calorimetry approach. In most of the cases, divergence does not exceed 2–3%.
