摘要: 在搅拌釜式间歇反应器中研究了以负载Mg2+的HD-8型阳离子交换树脂为催化剂的 4-OH-TMP非均相氧化反应动力学。探讨了该反应的反应机理,推导出4-OH-TMP催化氧化动力学方程。其速度方程可表示为r=kCACB。从实验中得到反应活化能 Ea=50.96kJ/mol,反应速率常数 k=8.52×103exp(-50.96/RT),反应速率常数与催化剂用量之间的关系为k=38.6+6.19w-0.64w2。

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.
