| 摘 要： | 探讨了三氟硝基苯水解制备２，３－二氟－６－硝基苯酚的反应机理，推导出２，３－二氟－６－硝基苯酚的合成动力学方程，其速度方程可表达为ｒ＝ｋｃＡｃＢ。从实验数据得到反应活化能Ｅａ＝１１６．７ｋＪ／ｍｏｌ，反应速度常数ｋ＝２．９６×１０１７ｅｘｐ（－１１６．７／ＲＴ）。用建立的动力学方程去预测不同条件下的转化率，计算值与实验值相比较１５个数据点的平均相对误差小于５．４％

| Abstract: | The mechanism of hydrolysis of 2,3,4trifuoro nitrobenzene have been studied in this work. The rate equation of hydrolysis was derived as r=kcAcB. The activation energy Ea=116.7kJ/mol and the rate constant k=2.961017exp(116.7/RT) . Based on this kinetic equation, the average deviation of conversion between the experimental data and calculated values at the data points was about 5.0%. |
