Reactions of oxygenated radicals in the gas phase. Part 11. Reaction of isopropylperoxyl radicals with 2,3-dimethylbut-2-ene
Abstract
The reaction of isopropylperoxyl radicals with 2,3-dimethylbut-2-ene has been studied between 303 and 363 K, using the photo-oxidation of trans-2,2′-azopropane as a source of the radicals. The only product formed from the alkene is 2,3-dimethyl-2,3-epoxybutane. From a detailed study of the products, Arrhenius parameters for reaction (22) of log (A/dm3 mol–1 s–1)= 7.96 ± 0.50 and E/kJ mol–1= 40.87 ± 1.78 have been obtained.
