Abstract
The photo-oxidation of 2,2′-azopropane has been studied in order to determine the overall rate constant for the second-order removal of isopropylperoxy radicals. Arrhenius parameters of log10(Aobs/dm3 mol–1 s–1)= 9.15 ± 0.03 and Eobs= 18.65 ± 0.50 kJ mol–1 have been determined over a temperature range 300–373 K. These values are compared with those obtained for the self-reactions of primary and tertiary alkylperoxyradicals, and the corresponding reactions in solution.Keywords
