- Аннотация: A reaction scheme is suggested for the nonbranched-chain free-radical oxidation of hydrocarbons. The scheme includes the formation of a low-reactivity radical RO4 center dot (e.g., o-CH3C6H4CH2O4 center dot) not participating in further chain propagation. This reaction can effectively compete with reactions of chain propagation via the reactive hydrocarbon radical R-center dot and, as the oxygen concentration in the reaction mixture is increased, begins to inhibit the chain process. The kinetic equation derived from the reaction scheme using the quasi-steady-state treatment provide a description for the nonmonotonic (peaking) dependence of the rate of the chain formation of molecular oxidation products on the oxygen concentration. The energetics of key radical-molecular reactions is considered, and the reaction scheme suggested is applied to the nonbranched-chain hydrogen oxidation involving the low-reactivity radical HO4 center dot
