Reactions of alkylperoxyl radicals in solution. Part 1.—A kinetic study of self-reactions of 2-propylperoxyl radicals between 135 and 300 K

Abstract

Absolute rate constants for the self-reaction of 2-propylperoxyl radicals in solution have been obtained over a wide temperature range and in four solvents. The kinetic behaviour is in agreement with that reported for other secondary peroxyl radicals in solution, but is not entirely consistent with the corresponding data for the 2-propylperoxyl radical in the gas phase. The thermodynamics of the equilibrium between the radicals and their dimer have been investigated to interpret their behaviour below 200 K.
