摘　　要：合成了一种新的含铜高能配合物,通过化学分析确定其组成为CuATZ.2H2O(ATZ2-=5,5′-偶氮四唑离子)。测定了配合物的溶解性,研究了配合物的生成反应过程。在实验和计算基础上,得到了298.15 K下液相生成反应的焓变ΔrHmθ(l)为(-39.182±0.097)kJ/mol。改变液相反应的温度,研究了液相生成反应的热动力学。在所研究的温度范围内,反应的表观活化能E值(24.8805 kJ/mol)比较低,说明该高能配合物具有普通条件下合成的可能性及可行性,但室温下配合物毫克级用量对研磨非常敏感,热至60℃左右对摩擦、静电非常敏感,发生爆炸的危险性很大。归因于其对热、摩擦等的敏感性,不满足固体推进剂燃烧催化剂的特征。A new energetic complex of copper（Ⅱ） was prepared and identified as CuATZ·2H2O（ATZ^2-=5,5′-azotetrazolate） by chemical analysis.The solubility of the complex was determined.The enthalpy change of the liquid-phase reaction for the formation of the complex,ΔrHm^θ（l）,was determined to be（-39.182±0.097） kJ/mol at 298.15 K by microcalorimetry.On the basis of experimental and calculated results,the thermodynamic and kinetic parameters of the liquid-phase reaction for the formation of the complex were obtained at different temperatures.The lower apparent activation energy E（24.880 5 kJ/mol） benefited the proceeding of the reaction under ordinary experimental conditions.However the complex can not be used as a component in solid propellants due to its sensitivity to shock and impact at room temperature at mg quantity and increased risk of explosion upon friction and static charge at about 60 ℃.
