Reactions of oxygenated radicals in the gas phase. Part 13. Reactions of t-butoxyl radicals with alkanes and alkenes

Abstract

Rate date for the abstraction reactions between t-butoxyl radicals and some hydrocarbons have been determined between 399 and 434 K. The hydrocarbons studied were the alkanes, 2,2-dimethylpropane, butane, and 2-methylpropane; cyclohexane; and the alkenes, propene, 2-methylpropane, cis- and trans-but-2-ene, 2-methylbut-2-ene, and 2,3-dimethylbut-2-ene. The alkoxyl redicals were generated by thermolysis of di-t-butyl peroxide. The experimentally determined activation energies of some of these reactions are compared with those calculated by semi-empirical method.
