Estimation of the effectivity of the C60 and C70 fullerenes as inhibitors of the unconventional chain oxidation of сumene: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

Within the current work, the antioxidant effectivity of the C₆₀ and C₇₀ fullerenes has been quantitatively assessed with two strategies: the chemiluminescence methodology and semilogarithmic methodology for processing kinetic curves primarily based on the transformation of kinetic absorption curves at AIBN-induced cumene oxidation. As discovered, the measured values of the stoichiometric inhibition coefficient for C₇₀ fullerene (f = 5.1 and three.2) are larger than for C₆₀ (f = 1.1 and 1.1), which signifies the next inhibitory exercise of the C₇₀ fullerene as in contrast with C₆₀. On the identical time, each fullerenes show decrease reactivity towards peroxyl radicals generated upon the hydrocarbon oxidation compared with well-known antioxidants, ionol and α-tocopherol.
