Benzoyl peroxide conversion in triacetyl cellulose free from oxygen

The kinetics of benzoyl peroxide (BP) consumption in triacetyl cellulose (TAC) and those of the macromolecular fracture are reactions of first order; the rate constants of both these processes are the same for the same initial BP concentration present in the samples. The effective constants of BP co...

Description
Summary:The kinetics of benzoyl peroxide (BP) consumption in triacetyl cellulose (TAC) and those of the macromolecular fracture are reactions of first order; the rate constants of both these processes are the same for the same initial BP concentration present in the samples. The effective constants of BP consumption and decomposition products accumulation have been found to be linear functions of the original BP concentration. The effective activation energy is 28 kcal/mole in both cases. A reaction scheme explaining the found kinetics is examined.
