对溴苯酚歧化异构化反应动力学

Kinetics of disproportionation and isomerization of p-bromophenol

测定了在 15 0～ 180℃范围内对溴苯酚歧化异构化反应的动力学数据 ,提出了对溴苯酚的歧化异构化反应为一级不可逆平行反应 ,并选用 Powell法和定步长龙格库塔法相结合的数学方法拟合实验数据 ,估算了动力学模型参数 。

The kinetics of disproportionation and isomerization of p bromophenol was studied and the kinetics data were obtained in different temperature. The termperature range was 150～180℃. A first order irreversible parallel reaction mechanism was presented, with the establishment of corresponding kinetics model. The parameters were obtained with aid of Powell and fixed step Runge Kutta method. The calculated results show good agreement with the experimental data.
