Kinetics of the thermal decomposition of quinolide peroxides from 2,4,6-tri-tert-butylphenol

Various o- and p-quinolide peroxides (QP) of 2,4,6-tri-tert-butylphenoxyl have been synthesized and the kinetics of their thermal decomposition studied.
The thermal stability of the QP's is largely determined by the structure of the cyclohexadiene fragment, the o-QP's being less stable than the p-QP's by several factors. The rate constants for QP decomposition are comparable with the rate constants for breakdown of the usual initiators, and considerably greater than the corresponding constants for aliphatic hydroperoxides, the principal branching agents in hydrocarbon oxidations.
