Conclusions

  1. 1.

    The method of quasistationary concentrations in the kinetic description of free radical decomposition of azobisisobutyronitrile in the presence of 1,2-bis-(4,4′-dimethylaminophenyl)-1,2-diphthaloylethane was experimentally substantiated.

  2. 2.

    The catalytic activity of Co(III) acetylacetonate increases during decomposition of tert-butyl hydroperoxide, and the catalyst reacts with the tert-butylperoxyl radicals.

  3. 3.

    The reaction of copper (II) acetylacetonate with the free radicals formed during catalytic decomposition of cyclohexenyl peroxide is accompanied by the disappearance of the EPR signal of the copper ions.
