  • Oxidizing salts of cubyl amines
    Patent number: 4878968
    Abstract: A compound having the following formula: ##STR1## wherein R.sup.1 is --N.sup.+ H.sub.3 as found in claim 1 and R.sup.2 is either the same as F.sup.1 or hydrogen. "A" is an oxidizing anion, and X is selected to provide a neutral charge balance for the compound. A method of making a compound of the indicated structure from a compound of similar structure by an anion exchange process is also disclosed. Finally, propellant formulations incorporating the novel compounds of the present invention as fuels and oxidizers are disclosed.

  • Synthesis of 1,4-dinitrofurazano(3,4-b)piperazine
    Patent number: 4539405
    Abstract: The novel explosive compound, 1,4-dinitrofurazano[3,4-b]piperazine, is prred by the reaction of 2,3-dioximinopiperazine with a base, followed by the nitration of the intermediate furazano[3,4-b]piperazine. The nitrated compound has a density, detonation pressure, detonation velocity and Isp similar to RDX while being highly insensitive.

  • 1,4,5,8-Tetranitro-1,4,5,8-tetraazadifurazano-[3,4-c][3,4-h]decalin
    Patent number: 4503229
    Abstract: A novel explosive compound, 1,4,5,8-tetranitro-1,4,5,8-tetraazadifurazano[3,4-c][3,4-h]decalin is prepared by the reaction of 3,4-diaminofurazan and glyoxal in dilute hydrochloric acid, followed by the nitration of the intermediate 1,4,5,8-tetraazadifurazano[3,4-c][3,4-h]decalin. The nitrated compound has a higher density and detonation pressure and velocity than the known explosives HMX and HNB.

  • Insensitive polynitramine compound
    Patent number: 4485237
    Abstract: The energetic compound 2,4,8,10-tetranitro-2,4,8,10-tetraazaspiro [5.5]undecane(TNSU) is disclosed. A general method of making 1,3-dinitroso-1,3-diazacycloalkanes in a one pot synthesis by the condensation of the diamine and formaldehyde, followed by conversion to the nitroso compound with nitrous acid. The general method also provides for the production of the tetranitroso precusor of TNSU.
