摘要 用高效液相色谱对以三甲氧基苯甲醛(TMB)为原料合成甲氧苄氨嘧啶(TMP)的缩合反应的反应液进行原料和缩合产品的含量分析.通过对数据进行曲线拟和,得到了298.15K和308.15K两温度下的动力学方程式,求出TMB的反应级数为0.37,反应活化能Ea=71.73kJ·moL-1. In the course of condensation reaction of systhesizing trimethoprim(TMP) from trimethoxybenzaldehyde, the contents of material trimethoxybenzaldehyde(TMB) and condensation product in the reaction system are analyzed by high performance liquid chromatography(HPLC).Kinetics equations at 298.15K and at 308.15K are deduced, with the reaction series of TMB of 0.37.Apparent activation energy is 71.73kJ·moL-1.
