Abstract

The rate constant of the primary decomposition step was determined for four symmetrical and four unsymmetrical azoalkanes. From the experimental activation energies and some literature enthalpy data, the following enthalpies of formation of radicals and group contributions were calculated: ΔHƒ (CH3N2) = 51.5 ± 1.8 kcal mol−1, ΔHƒ (C2H5N2) = 44.8 ± 2.5 kcal mol−1, ΔHƒ (2−C3H7N2) = 37.9 ± 2.2 kcal mol−1, [NA‐(C)] = 27.6 ± 3.7 kcal mol−1, [NA‐(ṄA) (C)] = 61.2 ± 3.1 kcal mol−1.
