摘　　要：用2-偕二硝甲基-5-硝基四唑(HDNMNT)为原料,与羟胺中和反应,合成了2-偕二硝甲基-5-硝基四唑羟胺盐(HADNMNT),收率为98.4%。用FTIR,1H NMR,13C NMR,15N NMR和元素分析表征了其结构。用DSC研究了HADNMNT的热稳定性。用密度泛函理论及K-J方程计算了HADNMNT的爆速和爆压。在标准状态下(压强为6.86 MPa,膨胀比为70/1),采用最小自由能原理计算了HADNMNT单元推进剂的理论比冲。结果表明,升温速率为10℃·min-1的HADNMNT的DSC曲线的峰温为145.3℃。它的爆速、爆压和比冲分别为9.240 km·s-1,39.54 GPa和2639.8 N·s·kg-1。Hydroxylammonium 2-dinitromethyl-5-nitrotetrazolate（HADNMNT） was synthesized via neutralization reaction with hydroxylamine,using 2-dinitromethyl-5-nitrotetrazole（HDNMNT） as raw material.Its structure was characterized by FTIR,~1H NMR,^（13）C NMR,^（15）N NMR and elemental analysis.The thermal stability of HADNMNT was studied by DSC.The detonation velocity and detonation pressure of HADN MNT were calculated by a density function theory and K-J equation.The theoretical specific impulse of monopropellant HADNMNT was calculated by the principle of minimum free energy under the standard state（pressure is 68.9 MPa,expansion ratio is70：1）.Results show that the yield of HADNMNT is 98.4%,and the peak temperature of DSC curve at a heating rate of 10 ℃ ·min^（-1）is 145.3 ℃.Its detonation velocity,detonation pressure and specific impulse are 9.240 km·s,39.54 GPa and 2639.8 N·s·kg,respectively.
