Reactivity and mechanism of the action of C60 fullerene used as an inhibitor for the radical chain oxidation of 1,4-dioxane

Abstract

The kinetics and mechanism of the antioxidative action of С₆₀ fullerene are studied via highly sensitive manometry and kinetic spectrophotometry, based on the example of a model reaction of the initiated oxidation of 1,4-dioxane. The adequacy of the proposed mechanism according to the experimental data is analyzed by means of mathematical modeling. The mechanism behind the inhibiting process is found to be a multi-center radical reaction. The rate constants of the elementary stages are determined.
