TL;DR: In this article, a gas-generative composition consisting of ammonium perchlorate with a chlorine scavenger, such as strontium nitrate, barium nitrates, potassium nitrate or lithium carbonate, is described.
Abstract: This invention relates to gas-generative compositions consisting essentially of ammonium perchlorate with a chlorine scavenger, such as strontium nitrate, barium nitrate, potassium nitrate, or lithium carbonate, the combination being present in an amount of about 30 to about 95 % by weight, up to about 5 % by weight of a binder, up to about 5 % by weight of a burning rate catalyst, together with an organic fuel, such as guanidine nitrate. The fuel is in an amount complementary to the combined weight of ammonium perchlorate, burning rate catalyst, chlorine scavenger, and binder, at an oxidation ratio of 0.90 to 0.98. The invention also includes the method of inflating an inflatable device by generating gas employing the noted composition and a gas generator in which the gas-generative composition is that of the present invention.

TL;DR: In this article, the supercooling temperature of primary nucleation of potassium nitrate from aqueous solution at a fixed concentration (46.0 wt%) and at a constant cooling rate (1.87×10−3°C/s) was analyzed by using the two-kind active site model, in which the nucleation is induced heterogeneously and in a stochastic manner by the active sites of two kinds of activities.

TL;DR: In this article, the degradation products and reaction products of butyl hydroxy anisol (BHA) with Sodium nitrite or potassium nitrate by irradiation of UV-ray were reported.
Abstract: In our previous works, we reported many degradation products and reaction products of butyl hydroxy anisol (BHA) with Sodium nitrite or potassium nitrate by irradiation of UV-ray. These compounds were as follows:Reaction products: 1, 4-dimethoxy-2-nitrobenzene (I), 1-hydroxy-2-tert-butyl-4-methoxy-6-nitrobenzene (II), 1, 4-dimethoxy-2-tert-butyl-6-nitrobenzene (III), 1, 4-dihydroxy-2-tert-butyl-6-nitrobenzene (IV). Degradation products: 2-tert-butyl-quinone (V), 2-tert-butyl-hydroquinone (VI), 2-tert-butyl-1, 4-dimethoxy-benzene (VII), 2′, 3-di-tert-butyl-2-hydroxy-4′, 5-dimethoxy biphenil ether (VIII), 3, 3′-di-tert-butyl-2, 2′-dihydroxy-5, 5′-dimethoxy biphenyl (IX), 3, 3′-di-tert-butyl-2′-hydroxy-2, 5, 5′-trimethoxy biphenyl (X), 3, 3′-di-tert-butyl-2, 2′, 5, 5′-tetramethoxy biphenyl (XI)In the present paper, we studied on mutagenicity of these compounds. Compound-VI showed a notable mutagenicity in the rec-assay using wild and recombinationless strains of Bacillus subtilis and sensitivity test using wild and rad mutant strains of Yeast in comparison with original materials.

TL;DR: In this article, the catalytic decomposition of N2O was investigated over Fe-BEA zeolites treated with various methods such as reduction, steaming and dissolution with potassium nitrate and nitric acid solutions in order to deduce the essen- tial components of the active sites for the decomposition.
Abstract: The catalytic decomposition of N2O was investigated over Fe-BEA zeolites treated with various methods such as reduction, steaming and dissolution with potassium nitrate and nitric acid solutions in order to deduce the essen- tial components of the active sites for the decomposition. The iron species were characterized by XPS, XANES, ESR, NO adsorption, and linear sweep voltammetry. The reduction-treated Fe-BEA zeolite with the large amounts of Fe(II) and Fe(III) species showed the highest activity. On the contrary, the dissolution treatment with the potassium nitrate solution seriously deteriorated the catalytic activity of the Fe-BEA zeolite by agglomerating iron oxide clusters and interaction between iron and potassium atoms. The catalytic roles of Fe(II)/Fe(III) species and the negative effect of potassium on the catalytic activity of the Fe-BEA zeolites were discussed.
