Thermodynamic properties of ideal gas nitro and nitrate compounds

The ideal gas thermodynamic properties of 27 organic nitro and nitrate orga nic compounds and two of their radicals are presented. Most of these compou nds are high explosives (TNT, RDX, HMX, PETN, NPN, and NG), while others se rve as propellants or specialty fuels (such as nitromethane). The thermodyn amic properties were calculated using fundamental molecular data. The molec ular data were gathered from the literature or calculated for this purpose. The enthalpy of formation of gaseous 1-nitropentane was estimated to be - 164.431 kJ mol(-1) (- 39.3 +/- 0.5 kcal mol(-1)); that of 1-nitrohexane to be - 185.351 kJ mol(-1) (- 44.3 +/- 0.7 kcal mol(-1)) for the ideal gas and - 241.835 kJ mol(-1) (- 57.8 +/- 0.7 kcal mol(-1)) for the liquid.
