HETEROGENEOUS REACTIONS OF FREE-RADICALS IN THE OXIDATION PROCESSES

The role of heterogeneous reactions of-free radicals in oxidative reac tions of different types (homogeneous gas-phase oxidation, stabilized combustion, heterogeneous catalytic oxidation) was analyzed. It was sh own that in all cases the apparent kinetic features and the products c omposition can be determined by the totality of simultaneously proceed ing and reciprocally influenced heterogeneous and homogeneous steps of the same nature. Possible mechanism of heterogeneous formation and tr ansformations of free radicals is discussed. The methods used for the studies of heterogeneous reactions of free radicals are characterized.
