Effect of Solvents on the Decomposition of Hydroperoxides and Reactions of Phenoxyl Radical Loss

Abstract

The influence of the properties of the medium on the rate of radical processes can be generalised by means of multiparameter equations taking into account the different properties of the solvents. The applicability of this approach is demonstrated for the case of the decomposition of tetralin hydroperoxide and lithium salt of tert-butyl hydroperoxide, and also the recombination of phenoxyl radicals. In all cases, an important role is played by the cohesive energy density of the solvents, i.e. their self-association.
