Reactions of oxygenated radicals in the gas phase. Part 7. Reactions of methylperoxyl radicals and alkenes

Abstract

The reactions of methylperoxyl radicals with alkenes have been studied between 373 and 403 K. The peroxyl radicals were generated by the oxidation of di-t-butyl peroxide. Arrhenius parameters for reaction (18) have been CH₃O₂·+CC→ [graphic omitted] + CH₃O·(18) determined for 2-methylbut-1-ene, 2-methylbut-2-ene, and 2,3-dimethylbut-2-ene. They are log(A₁₈/dm³ mol^–1 s^–1)= 8.60 ± 0.72,8.16 ± 0.49, and 8.14 ± 0.32, and E₁₈= 52.8 ± 5.4, 42.4 ± 3.6, and 36.4 ± 2.8 kJ mol^–1, respectively.
