The possibility of regime changing in chain reactions with degenerate branching under the influence of external magnetic field

A reaction of hydrocarbons oxidation in the liquid phase is treated theoretically. The reaction system under discussion is a flow reactor, to the inlet of which the hydrocarbon is constantly delivered in the mixture with an inhibitor under oxygen saturation conditions; the reaction mixture constantly flows from the chamber at the same rate. The reaction gives rise to radicals that can subsequently recombine. It is shown that under certain conditions in this reaction system, three steady states may arise, two of which are stable and the third state is unstable. By varying rate constants of radical reactions by means of an external magnetic field, one can disturb the steady state stability and transfer the system to another steady state, which will be accompanied by an abrupt change in the concentration of reacting substances.
