Kinetik und Mechanismus der Oxydation von 1,2,4,5-Tetramethylbenzol in essigsaurem Medium

The liquid phase oxidation of 1.2.4.5-tetramethylbenzene catalysed by cobaltous acetate and promoted by KBr in acetic acid was kinetically studied. In view of deriving the kinetic equation for the absorption of oxygen, a number of experiments were carried out. The values of the activation energy and of the preexponentA=10¹⁴ were determined as well. The resulting kinetic equation: $$ - frac{{dleft[ {O_2 } right]}}{{dtau }} = 10^{14} cdot exp left( { - frac{{84,460 times 10^3 }}{{RT}}} right) cdot C_{C_6 H_2 (CH_3 )_4 }^{0,5} cdot C_{Co(OAc)_2 }^{0,5} cdot C_{KBr}^{0,5} $$ is in accordance with the theoretically derived expression of this type.
