摘　　要：丁硝胺乙基硝酸酯(BuNENA)叠氮化是合成2-叠氮乙基丁硝胺(BuAENA)的经典方法.利用高效液相色谱法跟踪反应过程中原料浓度随时间的变化情况,对该反应动力学进行了研究.通过对实验数据的拟合,得出了62,70和80℃下的反应速率常数.结果表明反应为二级反应,分反应级数各为一级,反应的表观活化能Ea为85.06 kJ·mol-1.反应物的浓度和温度对反应速率影响较大.The reaction of 2-[butyl（nitro）amino]ethyl nitrate（BuNENA） with sodium azide is a classi-cal method for synthesis of butyl（2-azidoethyl）nitramine（BuAENA）.The kinetics of this reaction was in-vestigated at 62,70 and 80 ℃.The concentration of BuNENA in reaction process were determined by high performance liquid chromatography（HPLC） and the reaction rate constants were obtained by fitting the ex-perimental data.The results showed that the overall reaction was of the second-order and the order of reac-tion for 2-[butyl（nitro）amino]ethyl nitrate and sodium azide was first-order for each,the apparent activation energy was 85.06 kJ·mol-1.It was demonstrated that the velocity of the reaction was greatly influenced by concentration of reactants and reaction temperature.
