Abstract (EN): The standard (p degrees = 0. 1 MPa) molar enthalpies of formation, Delta(f)H degrees(m), for crystalline 1 -hydroxyisoquinoline, 5-hydroxyisoquinoline and 1,5-diidroxyisoquinoline, were derived from the standard molar enthalpies of combustion, in oxygen, at the temperature 298.15 K, measured by static bomb-combustion calorimetry. The standard molar enthalpies of sublimation, Delta(cr)(g)H degrees(m), at T = 298.15 K, were determined by Calvet microcalorimetry. The results were as follows: [GRAPHICS] The derived standard molar enthalpies of formation, in the gaseous state, are analysed in terms of enthalpic increments and interpreted in terms of molecular structure.
