| Abstract: | The enthalpies of combustion of 3-formylchromone (3F), 3-formyl-6-methylchromone (3F6M) and 3-formyl-6-isopropylchromone (3F6I) were determined by combustion calorimetry. The molar combustion energies ( ) of the 3F, 3F6M and 3F6I are: ?(4452.4 ± 1.8), ?(5115.6 ± 2.7) and ?(6411.4 ± 2.5) kJ mol?1, respectively. The formation enthalpies in the crystalline state ( ) are: ?(340.2 ± 2.2), ?(355.1 ± 3.1) and ?(415.5 ± 3.0) kJ mol?1, respectively.s |
