Abstract
Overall rate constants for the self-reaction of prop-2-ylperoxyl radicals in the liquid phase (cyclohexane, decane and dodecane) have been measured over the temperature range 293–373 K using ultraviolet absorption spectroscopy to monitor the concentration of alkylperoxyl radicals. The Arrhenius constants for the self-reaction are Et= 20 ± 3 kJ mol–1 and 2At=(5 ± 2.5)× 109 dm3 mol–1 s–1. Above 363 K there is evidence that reaction with the solvent becomes increasingly important.
