针对ＰＣｌ３氧气直接氧化生成ＰＯＣｌ３的气液相反应，采用鼓泡搅拌釜，通过改变通氧速率、反应温度、搅拌转速和氧初始分压，测定了反应液中ＰＣｌ３浓度随反应时间的变化关系，经数据处理和分析判别，确定了在实验操作范围内反应过程的宏观动力学类型，建立了相应的宏观动力学模型，求得了有关模型参数。 Aiming at the gas-liquid reaction of direct oxidation of PCl3 to POCl3, the change of PCl3 concentration in the reaction solution was determined by changing the oxygen passage rate, reaction temperature, stirring speed and oxygen partial pressure. After data processing and analysis, the macroscopic kinetic types of the reaction process in the experimental operating range were determined, and corresponding macroscopic kinetic models were established, and relevant model parameters were obtained.
