Conclusions
-
1.
The heats of combustion of nitromethane and dinitromethane, 168.0±0.3 and 137.3±0.2 kcal /mole, respectively, were measured.
-
2.
The energies (kcal/mole) of dissociation of the C-N bond in nitro derivatives of methane were estimated on the basis of the available data: 60.3 in nitromethane, 53.8 in dinitromethane, 45.7 in trinitromethane, and 39.3 in tetranitromethane.
-
3.
The energies (kcal/mole) of formation of nitromethyl radicals\([^ \cdot CH_2 NO_2 31.6;^ \cdot CH(NO_2 )_2 37.5;\) and\(^ \cdot C(NO_2 )_3 49.8]\) were estimated, and lead to energies of dissociation of the C-H bond in nitro derivatives of methane ∼103 kcal/mole.
