【Abstract】 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.更多还原
