On the equilibrium of peroxy radicals in the oxidation of 2-propanol by molecular oxygen

摘要

Based on kinetic data, it is demonstrated that the 1-hydroxy-1- methylethylperoxyl and hydroperoxy radicals are at equilibrium in the oxidation of 2-propanol at 323 C initiated by azobisisobutyronitrile. It is shown that the equilibrium of between the peroxy radicals is not disturbed within the covered range of alcohol concentrations. The rate constants of the reaction of the hydroperoxy radical with 2-propanol is determined: k _(2.2) = (0.13 ± 0.04) L mol~(-1) s~(-1).
