摘　　要：以含有甲酸、二甲胺的DMF水溶液实验数据为基础,研究了宏观反应体系DMF水解反应动力学,建立了DMF水解反应动力学模型。对实验数据进行了拟合处理,拟合曲线与实验数据点吻合较好,拟合曲线上的点可以近似表示反应的真实趋势,从而证明所建DMF水解动力学为表观一级反应模型成立。计算了在实验温度条件下的DMF水解活化能(Ea)。DMF水解反应动力学模型的建立,为DMF水解反应机理的深入探讨提供了基本的理论依据。Based on the experimental data obtained by the DMF solution containing formic acid and dimethylamine（DMAM）, the hydrolysis kinetics of DMF was studied and the kinetic model of hydrolysis was established. The experimental data was correlated. The results showed that the correlation curve was in good conformity with experimental data and the kinetic model of hydrolysis was first order. Moreover, the activation energy of DMF hydrolysis under the experimental temperature was calculated.
