Conclusions

  1. 1.

    Study has been made of the stoichiometry and kinetics of the oxidation of hydrogen peroxide by salts of 2,2,6,6-tetramethyl-1-oxopiperidine and 2,2,6,6-tetramethylpiperidin-1-oxyl. Piperidinoxyl, the primary product resulting from reduction of the oxopiperidine cation, is formed through electron transfer from HO 2 to\(\begin{array}{*{20}c} \setminus \\ / \\ \end{array} \mathop N\limits^ + = O\). The oxidizing action of the nitroxyl radical results from its acid disproportionation into\(\begin{array}{*{20}c} \setminus \\ / \\ \end{array} \mathop N\limits^ + = O\) and\(\begin{array}{*{20}c} \setminus \\ / \\ \end{array} N---OH\).

  2. 2.

    Rate constants have been determined for the reaction of HO 2 and HO .2 with\(\begin{array}{*{20}c} \setminus \\ / \\ \end{array} \mathop N\limits^ + = O\).
