摘要：
The catalytic oxidation of dodecane by air oxygen on a mixed vanadium-molybdenum oxide (V2O5 · MoO3, 40 mol % MoO3) was studied over the temperature range 300–350°C. The reaction at 300–330°C occurred on oxygen vacancies with the rupture of C-H bonds and formation of α-acid. Oxidation above 350°C occurred with the splitting of the C-C bond and formation of two and more acids. Singlet oxygen 1O2 generated in the oxidation of oxide catalyst lattice oxygen participated in the reaction. A possible mechanism of the process was considered.
