摘　　要：对间甲苯胺重氮盐的水解反应动力学进行了研究,考察了重氮盐浓度及反应温度对反应速率的影响,测定了反应级数及表观活化能。结果表明,间甲苯胺重氮盐的水解反应近似于一级反应,温度对反应速率的影响符合阿伦尼乌斯方程,表观活化能为98.3 kJ/mol。The purpose of the study of the hydrolysis kinetics of m-toludine diazonium salt was to investigate effect of the concentration of diazonium salt and temperature on reaction rate to determine the order of reaction and the apparent activation energy.The results indicated that the hydrolysis of m-toludine diazonium salt was similar to the first order reaction.The effect of temperature on reaction rate can be correlated to the Arrhenius equation with the apparent activation energy of 98.3 kJ/mol.
