Conclusions

  1. 1.

    The completeness of the oxidation of an organic substance by oxides in a flow-type system depends not only upon the effectiveness of the oxidizing agent, but also upon the rate of delivery of the substance to the oxidizing layer and upon the physical and chemical properties of the substance. In the classical method of decomposition of the sample, identical conditions guaranteeing an equal degree of oxidation of various substances cannot be ensured.

  2. 2.

    In decomposition in a semiclosed system (with delivery of the products of thermal decomposition of the substance to the oxygen-rich zone), complete oxidation of the organic substance is ensured independent of the use of an oxidizing agent.

  3. 3.

    When the oxidation was conducted in an inert gas atmosphere, nickel oxide proved to be the most active of the tested oxidizing agents.
