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.
