Abstract Scalable synthesis of high purities ammonium dinitramide (ADN), 98.2% or more has been performed through conversion of potassium dinitramide (KDN) into ammonium dinitramide using guanylurea dinitramide (GUDN) as a precursor, which can be scalable up to a few hundred grams. The obtained ADN and corresponding liquid ADN blended with fuel was subject to the decomposition reaction with and without iridium catalyst. The result of the decomposition reaction suggested that the blending of methanol with ADN gave a high performance. It has been shown that the presence of ammonium hydroxide in the blend maintained pH around 10 and also stabilized the ADN solution for more than 20 day at 60 °C.

高纯二硝胺铵的规模化合成及其分解特性

摘要 以二硝胺鸟苷 (GUDN) 为前驱体，将二硝胺钾 (KDN) 转化为二硝胺铵，可规模化合成 98.2% 或更高纯度的高纯度二硝胺铵 (ADN)，可规模化至数百克. 得到的ADN和相应的与燃料混合的液体ADN在有和没有铱催化剂的情况下进行分解反应。分解反应的结果表明，甲醇与 ADN 的混合产生了高性能。已经表明，混合物中氢氧化铵的存在使 pH 值保持在 10 左右，并且还使 ADN 溶液在 60°C 下稳定了 20 多天。
