Methods of making and resultant compositions thereof, which include copper-oxalyldihydrazide-based complexes, such as pyrotechnic compositions, gas generants, and ignition materials, which are useful, for example, in inflatable restraint systems. Synthesis of one or more copper-oxalyldihydrazide complexes with nitrate and/or hydroxide counter ions provides a composition that may auto-ignite at a low enough temperature to be based with thermally sensitive gas generants. The present copper-oxalyldihydrazide complexes may also be used in conjunction with various oxidizers to produce compositions with sufficient energy to auto-ignite practically any known pyrotechnic composition.

摘要:
Extrudable gas generant compositions which, upon combustion, produce or result in an improved effluent and related methods for generating inflation gas for use in an inflatable restraint system are provided. Such extrudable gas generant compositions include a non-azide, organic, nitrogen-containing fuel, at least one copper-containing compound, a perchlorate additive and a polymeric binder material. The at least one copper-containing compound may be selected from basic copper nitrate, cupric oxide, a copper diammine-ammonium-nitrate mixture wherein the ammonium nitrate is present in the mixture in a range of about 3 to about 90 weight percent, and/or a copper-nitrate complex resulting from reaction of 5-aminotetrazole with basic copper nitrate. The perchlorate additive is present in an amount effective to result in a gaseous effluent, when the gas generant composition is combusted, having a reduced content of at least one species selected from carbon monoxide, ammonia, nitrogen dioxide and nitric oxide, as compared to a same gas generant free from the perchlorate additive. The polymeric binder material is effective to render the gas generant composition extrudable.
摘要:
What is described is the use of a microjet reactor for the production of initiating explosive, each of the starting solutions for explosive production in the microjet reactor being injected through a nozzle onto a common collision point into a reactor space enclosed by a reactor housing, a gas being admitted into the reactor space via an opening, and the resulting initiating explosive crystals being removed from the reactor housing together with the liquid and excess gas through a further opening.

Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a cationic metal template, sufficient oxidizing anion to balance the charge of the complex, and a neutral ligand containing hydrogen and nitrogen. The complexes are formulated such that when the complex combusts nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite ammine, metal nitrate ammine, and metal perchlorate ammine complexes, as well as hydrazine complexes. Such complexes are adaptable for use in gas generating devices such as automobile air bags.
摘要:
Nonazide gas generating compositions are formed from a nonazide fuel, an oxidizer, a slag former, and a built-in catalyst comprising an alkali metal, alkaline earth metal, or transition metal salt of tetrazoles, bitetrazoles, and triazoles, or a transition metal oxide. The built-in catalyst promotes the conversion of nitrogen oxides (NO.sub.x) and carbon monoxide to nitrogen gas (N.sub.2) and carbon dioxide, respectively. The gas generants are therefore nontoxic and useful for inflating a vehicle occupant restraint system.
