| 摘 要： | 在偏三甲苯氧化动力学研究的基础上建立了偏三甲苯液相空气氧化制备偏苯三酸的间歇反应模型。该模型考虑了气液相间传质与氧化反应的相互作用,应用渗透模型理论揭示了宏观反应速率随时间的变化关系,通过求解反应过程的质量和热量衡算方程,模拟得到了反应过程中主要组分浓度的变化。用此模型对年产200吨偏苯三酸的中试反应器进行模拟,并与实际数据进行了比较。结果表明,主要组分以及溶剂醋酸消耗的模拟值能同实验值相吻合,验证了模型的合理性。

| Abstract: | A model for gas oxidation of 1,2,4-trimethylbenzene in the batch reactor was devel- oped.The interaction between gas-liquid mass transfer and oxidation reaction was considered for this model.The correlation between macro-reaction rates and time was obtained based on the pene- tration theory.The batch process for oxidation of 1,2,4-trimethylbenzene in acetic acid solvent with air was simulated with developed model.The simulated results were good agreement with that of plant running,which verified the reliability of the model proposed. |
