摘要：
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.
