Reaction rate pulsation during liquid-phase oxidation of hydrocarbons

Rate oscillations in cyclohexane oxidation

“…The reaction came to a standstill as the temperature was lowered below a certain value, and could not be restarted until the temperature was increased much beyond this value. Hronec and Ilavsky (1982) reported aperiodic oscillations in the exit oxygen concentrations in the isothermal oxidation of a mixture of a p-xylene and p-toluic acid (catalyzed) and of n-Dodecane (uncatalyzed) in an air-sparged reactor. A number of papers (Jensen, 1983;Roelofs et al, 1983;Reimus et al, 1989Reimus et al, , 1990 discussed oscillations in the air-oxidation of benzaldehyde under the catalytic influence of C02+/Br.…”
