Reactions of oxygenated radicals in the gas phase. Part 3. Reactions of peracetyl radicals with alkenes

Abstract

Rate constants for the addition reactions of peracetic acid and peracetyl radicals with alkenes have been determined at 393 K [reactions (1) and (2)]. The alkenes studied were propene, 3-methylbut-1-ene, cis- and trans-pent-2-ene, [graphic omitted] [graphic omitted] 2-methylbut-1-ene, 2-methylbut-2-ene, and hex-1-ene. Arrhenius parameters for the reactions with 2-methylbut-2-ene have been determined as follows: log₁₀(k₁/dm³ mol^–1 s^–1)=(8.23 ± 0.33)–[(61 600 ± 2 420) J mol^–1/2.3RT] log₁₀(k₂/dm³ mol^–1 s^–1)=(8.08 ± 0.12)–[(16 340 ± 910) J mol^–1/2.3RT].
