Abstract
The kinetics of decomposition of isobutyryl peroxide was investigated in isooctane solution. The decomposition was shown to be unimolecular, the activation energy being 27.3 kcal/mole and the frequency factor 2.8·1014 sec—1. The lower activation energy of this decomposition, as compared with decompositions of other acyl peroxides, suggests that energy is supplied to the O–O bond by the decarboxylation of radicals resulting from the dissociation of this peroxide. The problem of energy supply is taken further in the following publication. The reactions of isopropyl radicals formed in the dissociation process were studied quantitatively.Keywords
