[New kinetic model of the radical-chain oxidation, including competitive reactions: oxygen as an autoinhibitor].
The application of competitive kinetics to the process of nonkatalytic oxidation by the radical-chain nonbranched mechanism was considered using the homogenous liquid phase oxidation of orthoxylene as an example. It was assumed that the free cycloalkylhydrotetraoxyl radical [formula: see text] is the intermediate compound that inhibits the chain process. By the method of quasi-stationary concentrations, kinetic equations for the rates of formation of oxidation products (alkylhydroperoxide, alcohols, carbonyl compounds, etc.) were derived in which 1-3 parameters should be determined.
