摘要:
在开发成功的2-甲基-1,4 对苯二酚催化合成工艺过程的基础上, 研究了对硝基甲苯在催化剂作用下,合成2-甲基-1,4 对苯二酚的反应动力学,提出连串反应机理,用体系生成物浓度变化量随时间的变化率表示体系的反应速度,建立了动力学模型,确定了模型中的参数,并对提出的动力学模型进行了实验验证.实验表明,在温度356.15~368.15 K范围内,反应的表观活化能Eα=67.7750 kJ·mol-1,介于一般化学反应活化能40~400 kJ·mol-1之间,属于化学反应控制过程.
Abstract:
Based on the successful development of the catalytic synthesis process of 2-methyl-1,4 hydroquinone, the reaction kinetics of the synthesis of 2-methyl-1,4 hydroquinone under the action of catalyst were studied, a series reaction mechanism was proposed, the reaction speed of the system was expressed by the change rate of the concentration of the system with time, the kinetic model was established, the parameters in the model were determined, and the proposed kinetic model was experimentally verified. Experiments show that in the temperature range of 356.15~368.15 K, the apparent activation energy of the reaction Eα=67.7750 kJ·mol-1, which is between 40~400 kJ·mol-1 of the general chemical reaction, belongs to the chemical reaction control process.
