摘要
研究了以甲苯、氯气为原料，在光催化条件下反应的产物分布规律。该项目研究是工业连续催化蒸馏技术应用的化学动力学基础。根据动力学基本方程并经合理简化，进行了甲苯、氯气反应体系的有关理论推导，得出了该反应体系的动力学方程，列出了可能的影响因素，并进行了实验研究。结果表明，甲苯光氯化反应可表示为一典型的拟一级反应动力学方程，并由实验验证了一氯苄的产物分布方程。反应温度不是影响该反应体系选择性的关键因素。不同反应温度下的参数Ｋ值，已由实验测定。
In this paper,the photochlorination of toluene was studied and analyzed. The toluene and chlorine were used as raw materials and the product distributions were determined. According to the basic dynamics equation, the reasonable kinetics equation and the possible affecting factor of the reaction system were inferred by rational process simplify. The results of experiments indicate that the rates of toluene photochlorination reaction can be expressed by a series of pseudo-first order dynamics, and its product distribution function is identified by experiments.The thermometer of the reaction system is a unimportant factor.The values of parameter K under varied thermometer conditions have been estimated by experiment.The results are of the value for developing an industrial successive catalytic distillation technique.
