Influence of organic acids on the mechanism of chain branching in the oxidation of n-decane

  • 20 Accesses

Conclusions

  1. 1.

    The rate of consumption of an inhibitor in the decomposition of n-decyl hydroperoxide in the presence of caproic acid was measured. It was shown that the rate of radical formation in the system increases with increasing concentration of the added acid.

  2. 2.

    A mechanism of chain branching at the profound stages of the oxidation of n-decane, including the formation of radicals in the interaction of the hydroperoxide with the acid, was proposed. The rate constant and activation energy of this process were determined.

  3. 3.

    The rate of chain branching, measured experimentally, coincides with that calculated according to the proposed mechanism over the extent of the entire process of oxidation of n-decane.

  4. 4.

    The elementary event of interaction of hydroperoxide with the acid is facilitated by the formation of inter-molecular hydrogen bonds.
