Conclusions
-
1.
The following thermochemical parameters of N, N-dimethylnitrosoamine were obtained: heat of combustion (382.3±1.5 kcal/mole), heat of formation in the standard state (−10.7±1.5 kcal/mole), heat of evaporation (9.9±0.5 kcal/mole), and heat of formation in the gas phase −0.8±2 kcal/mole).
-
2.
The temperature dependence of the first-order rate constants was established for the initial stage of the thermal decomposition of dimethylnitrosoamine.
-
3.
The difference of the energies of the N-N bond in dimethylnitrosoamine and dimethylnitroamine, obtained from the thermochemical and kinetic data, is equal to 14.1±5.2 and 11.3±3.0 kcal/mole respectively.
-
4.
Using the thermochemical data for dimethylamine, the values of the bond energies of N-N in dimethylnitroamine and dimethylnitrosoamine were estimated a −41.2 and 55.2 kcal/mole, respectively.
