Conclusions
-
1.
The enthalpies of combustion, vaporization, and formation of N-nitro- and N-nitrosomorpholine have been determined calorimetrically.
-
2.
Based on the kinetic data for the decomposition of N-nitro- and N-nitrosomorpholine in the gas phase it is concluded that the primary and rate-limiting step in these reactions is homolytic N-N bond cleavage.
-
3.
By comparing the thermochemical and kinetic data we have been able to determine the N-N bond dissociation energies in N-nitro- and N-nitrosomorpholine, as well as the N-O bond energy in N-nitromorpholine and the N-H bond dissociation energy in morpholine; these values were found to agree with literature data for the thermochemical parameters in related compounds.
