摘要(Abstract):
以负载氯化亚铜为催化剂,研究了苯乙烯和四氯化碳加成反应的动力学,为工业反应过程的开发和操作提供了理论依据。在本实验条件下,催化剂的粒径为10 8~10 7m,内扩散影响可以忽略。当搅拌速度大于210 r min 1时,外扩散影响基本消除,反应进入动力学控制区。系统地测定了65~75℃下的反应动力学数据。依据自由基加成反应机理和单活性位吸附的假设,建立了动力学模型,rA=K[CA][CB]+k1[CB]。对实验数据进行非线性拟合,得到反应动力学模型参数。计算得到其控制步骤解离吸附的反应活化能为1.11×105kJ mol 1。动力学模型与实验数据吻合较好,在实验范围内可信度较高。
