| Abstract: | The kinetics of 4-OH-TMP heterogeneous catalytic oxidation reaction catalyzed by ion exchange resin supported Mg2+ was studied. The reaction mechanism was. discussed and the 4-OH-TMP catalytic oxidation kinetics equation was derived as r=kCACB. They were obtained from the experiment that the activation energy Ea=50.96kJ/mol, the rate constant k=8.52×103exp(-50. 96/RT), the relation between rate constants and catalyst use level k=38.6+6.19w-0.64w2. |
