ABSTRACT
The standard (p = 0.1 MPa) massic energies of combustion in oxygen of 5-bromoindole and 5-bromoindoline were determined at T = 298.15 K by rotating-bomb calorimetry. These values were used to derive the standard molar enthalpies of combustion and the standard molar enthalpies of formation, in the condensed phase, for these compounds. Further, the standard molar enthalpies of sublimation, at T = 298.15 K were determined by Calvet microcalorimetry. The combustion calorimetry results together with those from the Calvet microcalorimetry, were used to derive the standard molar enthalpies of formation, at T = 298.15 K, in the gaseous phase.
