    • A process for producing 1,5-diazido-3-nitrazapentane (DANPE) which comprises the steps of nitrating diethanolamine with nitric acid in a halogenated solvent such as methylene chloride to form 1,5-dinitrato-3-nitrazapentane (DINA) as intermediate, solvent transferring such intermediate from the halogenated solvent to dimethylsulfoxide, adding sodium azide to the resulting solution to form DANPE as product, and solvent transferring such product from the dimethylsulfoxide to another halogenated solvent, e.g. methylene chloride. Thus, both DINA intermediate and DANPE product are prepared in solution, and both can also be purified in solution, eliminating the necessity for isolating the neat, hazardous compounds. The DANPE product can be further solvent transferred from the halogenated solvent to ethyl acetate to form an ethyl acetate solution of DANPE, which can be used to furnish the DANPE as an energetic plasticizer, e.g. in the production of gun propellants.
    • 一种制备1,5-二叠氮基-3-硝基氮烷(DANPE)的方法,其包括在卤化溶剂如二氯甲烷中用硝酸硝化二乙醇胺以形成中间体1,5-二硝基-3-硝基氮烷(DINA) 将这样的中间体从卤代溶剂转移到二甲基亚砜中,向所得溶液中加入叠氮化钠以形成DANPE作为产物,以及将这种产物从二甲基亚砜转移到另一种卤化溶剂中的溶剂,例如 二氯甲烷。 因此,在溶液中制备了DINA中间体和DANPE产品,并且两者都可以在溶液中纯化,从而无需分离纯净的有害化合物。 DANPE产物可以进一步从卤化溶剂转移到乙酸乙酯中以形成DANPE的乙酸乙酯溶液,其可用于提供DANPE作为能量增塑剂,例如, 在枪式推进剂的生产中。
