Conclusions
-
1.
The heats of combustion of N-nitropiperidine (789.6±0.4 kcal/mole) and N,N-dimethylnitramine (DMNA) (375.2±0.3 kcal/mole) were determined, and their standard enthalpies of formation were calculated, equal to −22.2±0.4 and −17.9±0.3 kcal/mole, respectively.
-
2.
The heat of evaporation of NP (11.6±0.2 kcal/mole) was determined and its enthalpy of formation in the gas phase (−10.6±0.5 kcal/mole) was calculated.
-
3.
The enthalpy of formation of the piperidyl radical (23.5±1.8 kcal/mole) was estimated.
