Description
Summary:The effect of C 60 fullerene derivatives containing maleopimarimide fragments on the kinetics of oxygen absorption in a model system of the initiated radical chain oxidation of ethylbenzene was studied. The test compounds manifested themselves as radical chain oxidation inhibitors. For all of the fullerene derivatives with maleopimarimide substituents, a significant duration of their inhibitory action was noted. The rate constants of inhibition fk 7 were measured. It was shown that the introduction of a maleopimarimide substituent into the fullerene molecule did not decrease the antiradical activity of the fullerene; moreover, it even increased this activity to fk 7 = 1 × 10 4 L mol –1 s –1 (333 K).
