    • Ethylenediamine salt of 5-nitrotetrazole and preparation. This salt has been found to be useful as an explosive alone and in eutectic mixtures with ammonium nitrate and/or other explosive compounds. Its eutectic with ammonium nitrate has been demonstrated to behave in a similar manner to a monomolecular explosive such as TNT, and is less sensitive than the pure salt. Moreover, this eutectic mixture, which contains 87.8 mol % of ammonium nitrate, is close to the CO.sub.2 -balanced composition of 90 mol %, and has a relatively low melting point of 110.5 C. making it readily castable. The ternary eutectic system containing the ethylenediamine salt of 5-nitrotetrazole, ammonium nitrate and ethylenediamine dinitrate has a eutectic temperature of 89.5 C. and gives a measured detonation pressure of 24.8 GPa, which is 97.6% of the calculated value. Both the pure ethylenediamine salt and its known eutectic compounds behave in substantially ideal manner. Methods for the preparation of the salt are described.
    • 5-硝基四唑的乙二胺盐及其制备方法。 已经发现该盐可用作单独的爆炸物和用硝酸铵和/或其它爆炸性化合物的共晶混合物。 其与硝酸铵的共晶已经被证明以类似于单分子炸药如TNT的方式表现,并且比纯盐更不敏感。 此外,含有87.8mol%硝酸铵的这种共晶混合物接近CO 2平衡组成为90mol%,熔点相对较低,为110.5℃,易于浇注。 含有5-硝基四唑,硝酸铵和硝酸二乙酯的乙二胺盐的三元共晶体系的共晶温度为89.5℃,测得的爆轰压力为24.8GPa,为计算值的97.6%。 纯乙二胺盐及其已知的共晶化合物都以基本理想的方式表现。 描述了制备盐的方法。
