The bell-shaped dependences of rate constants of oxydation of hydrocarbons by peroxynitrios acid (HOONO) on the ratio of volumes of the aqueous and gas phases in a reactor were explained quantita- tively assuming the distribution of the substrate and HOONO between gas and solution, formation of OH-radicals in two phases and their interaction with hydrocarbons. The coefficient of distribution of HOONO between gase and aqueous phases (α) was estimated to be (0.4-2)·10-6.

Key words: peroxynitrios acid, hydrocarbons, oxydation, kinetics, mechanism.
