✦ Synopsis

The decomposition of bis(pentafluorobenzoyl) peroxide in benzene at 60 Β° has been studied by radiotracer methods. By using low concentrations of the peroxide, the induced decomposition previously observed has been eliminated. The mechanism of the decomposition is found to be fundamentally similar to that for benzoyl peroxide under the same conditions. The rate constant for the decomposition (7.4 Γ— 10 -4 sec-1) is considerably larger than that for benzoyl peroxide, although the energy of activation for the dissociation (about 120 kJ mole-1) is of similar magnitude.

The decomposition of alkaline hydrogen peroxide solutions at 20Β°C has been studied in the presence of both supported iron catalysts and in systems with iron initially in solution. Studies with an iron-alumina supported catalyst showed the decomposition reaction was first order with respect to total
