Abstract (en)

[origin: WO0000365A2] A pyrotechnic gas generant composition includes a high oxygen balance compound or fuel, preferably, azodiformamidine dinitrate, which is the resulting reaction product of an aminoguanidine salt and nitric acid. Specifically, the high oxygen balance compound or fuel of the present invention is the resulting reaction product of aminoguanidine salts, such as aminoguanidine nitrate, aminoguanidine bicarbonate, or aminoguanidine sulfate with nitric acid. Preferably, the aminoguanidine salt is aminoguanidine bicarbonate. The resulting reaction product is a yellow precipitate that can be used alone, with or without oxidizers or other additives, for very rapid self-deflagration or in combination with oxidizers and additives. In each instance, the gas generant composition provides both high gas output and low production of solid combustion products. Further, the precipitant is relatively non-hygroscopic and has a high burn rate. The gas generating composition is useful as a gas generator for an air bag of an occupant restraint system for an automobile, gun propellants, inflation and expulsion devices, flotation devices, pyrotechnics, fire suppression devices and smokeless, reduced smoke and smokey rocket propellants.
