【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%.更多还原
