Abstract
The oxidation reaction between 2,6-di-tert-butylphenol (DTBP) and oxygen adducted Co(III) complexes as a catalysis has been studied by UV-visible spectrophtometry. According to the results, main product is 2,6-di-tert-butylbenzoquinone(BQ) and the activity of the complexes is bigger in [Co(III)2(SMPD)2(Py)2]2O2 than in [Co(III)2(SPPD)2(Py)2]2O2. The rate constant is 4.55~2.12${\times}$10$-3}$s. It was found that the oxidation reaction is primary reac-tion or concentration of catalysis, O2 molecule and substance. The reasult is far from Arrhenius properties because acti-vationenergy is 10.38 kJ/mol.
