The Rate Constant of the 2-Thio-6-Aminouracil Interactionw the Peroxyl Radical
It was shown that 2-thio-6-aminouracil (TAU) is an inhibitor of the radical chain oxidation of ethyl benzene and methyl oleate. The reactivity of peroxyl radicals of various structures in the reaction with TAU has been compared. The rate constant of this reaction decreases in the series: peroxyl radical of 1,4-dioxane, of ethyl benzene, and of methyl oleate (fk<sub>7</sub> × 10<sup>4</sup>, L mol<sup>–1</sup> s<sup>–1</sup>, 333 K) = 30 : 5.2 : 2.0. The reason for the decreasing in the reactivity of peroxyl radicals of ethylbenzene and methyl oleate was suggested.
