The antioxidant properties of cyclohexanone transformation products were investigated using model radical‑chain oxidations of 1,4‑dioxane and isopropyl alcohol by molecular oxygen (air) at a temperature of 348 K. Oxygen‑uptake kinetic curves during the oxidation process were obtained using a universal differential manometric setup under various initial conditions. It was shown that the compounds studied exhibit antioxidant activity, the mechanism of which varies depending on the nature of the oxidized substrate. For the two substrates examined, a reaction mechanism was proposed that satisfactorily agrees with the experimental data. Rate constants were determined that quantitatively characterize the efficiency of the antioxidant action.
