Extraction and recovery of nitramines from propellants, explosives, and pyrotechnics |
摘要 |
Nitramine oxidizers are recovered from propellant, explosive, and pyrotechnic materials with a concentrated mineral acid bath, preferably comprising 70 to 90 wt. % nitric acid, that serves to dissolve the nitramine oxidizers into solution and permit filtration of the binder therefrom. The recovery process is conducted in the absence of organic solvents.
