The antioxidant activity of the ascorbic acid (AA) in the process of  the initiated oxidation of the cumene has been studied. It has been established that the antioxidant activity of AA shows itself in relatively low concentrations ([AA]≤9,77·10-3 mol/l). Тhe number of radicals terminating on one molecule of AA has also been determined. (f is the antioxidant capacity). It has been shown that . In concentrations of AA 1·10-2 mol/l, the induction periods on the kinetic curves of oxygen absorption vanish.The regularities of the oxidation of AA in the solutions of  DMSO, DMSO+water, DMSO+ benzene chloride. It has been shown that water suppresses the rate of the oxidation of AA more whereas chlorobenzene does it 1,14 times more than in DMSO. It has been established that the rate of oxidation of AA in DMSO is described by the equation V=k[AK][O2]1/2, где k=1,14x103exp(-9440/RT).
