Definitions
- These materials may also consist of mixtures of oxygenliberating substances, such as potassium chlorate, and gas-evolving substances such as ammonium nitrate or guanidine nitrate. (See, for example, German patents 854,770, 851,919, and 909,424.)
- one aspect of this invention resides in novel pressurizinggas-producing charges, particularly for use in pressurizing-gas-actuated devices, which are characterized by the fact that they comprise from 40 to 100 weight percent aminoguanidine salts of azotetrazole and/or ditetrazole.
- Other components of the composition may include oxygen-liberating and/or other gas-evolving substances which do not cause detonation. These may be used singly or in combination in proportion of 0 to 60 weight percent.
- Azotetrazole has the formula and ditetrazole has the formula N N 111 1 I l
- the hydrogen atoms of these compounds have an acid reaction and consequently form, with aminoguanidine, the corresponding salts.
- These salts are prepared, for example, by mixing aqueous solutions of salts of aminoguanidine, such as aminoguanidine sulfate, with aqueous solutions of alkali salts of said tetrazoles.
- the insoluble salt compounds suitable for use in accordance with the present invention precipitate from this reaction mixture and can be recovered by conventional chemical engineering techniques.
- Suitable oxygen-liberating optional additives are chlorates, perchlorates and nitrates of inorganic bases which are all preferred. Nitroguanidine, guanidine nitrate, nitrocellulose, nitropolystyrene, polynitrophenols, polynitrocresols or the like can also be incorporated as oxygen liberators.
- Soleiy gas-evolving optional additives which are suitable are, for example, ammonium oxalate, urea, aminoguanidine, sugar, tartaric acid or the like.
- Catalysts promoting decomposition such as compounds of vanadium, tungsten, molybdenum, chromium, cobalt or the like, particularly in the highest degree of oxidation of the metal, may advantageously be added to the compositions of this invention in a proportion of from 0.5 to 5 weight percent, referred to the total mixture.
- compositions of this invention are prepared by simple mixing of the ingredients.
- the resultant solid composition may be pressed, but this is not absolutely necessary.
- EXAMPLE 1 A mixture of 500 g of azotetrazole-aminoguanidine salt and 500 g of barium nitrate was pressed into bodies which were then ignited in a pressure pipe with nozzle. A strong gas jet was thus produced. The mixture furnished 350 cc gas/g of mixture. It was not ignited by the shock of a falling weight of 2 kg dropped from a height of 2 meters.
- EXAMPLE 2 An intimate mixture of 700 g of ditetrazoleaminoguanidine salt and 300 g of potassium nitrate was pressed into bodies which were ignited in a pressure pipe with nozzle by the use of an electric primer pellet. The quantity of gas evolved was 400 cc/g. The mixture was not ignited by the shock of a falling weight of 2 kg dropped from a height of 2 meters.
- a pressure composition was prepared from 50 g of barium nitrate (Ba(NO 50 g of azotetrazoleaminoguanidine salt, 4 g of vanadium pentoxide V 0 and 15 g of an aluminum-titanium alloy. After ignition of the composition by means of an ignition mixture disposed in a central ignition tube, a reaction of the composition set in with evolution of heat. The heat generated was 768 cal/g.
- barium nitrate Ba(NO 50 g of azotetrazoleaminoguanidine salt, 4 g of vanadium pentoxide V 0 and 15 g of an aluminum-titanium alloy.
- EXAMPLE 4 A pressure composition was prepared from 40 g of barium nitrate (Ba(NO and 60 g of azotetrazoleaminoguanidine salt. After ignition of the composition by means of the ignition mixture disposed in a central ignition tube, a reaction of the composition set in with evolution of heat. The heat generated was 613 cal/g, Volumer, of evolved gas: 440 em /g.
- EXAMPLE 5 A pressure composition was prepared from 45 g of barium nitrate (Ba(NO 45 g of azotetrazoleaminoguanidine salt and g of amorphous boron. After ignition of the composition by means of the ignition mixture disposed in a central ignition tube, a reaction of the composition set in with evolution of heat. The heat generated was 826 cal/g, amount of evolved gas: 520 em /g.
- EXAMPLE 6 A pressure composition was prepared from 30 g of barium nitrate (Ba(NO 50 g of azotetrazoleaminoguanidine salt and g of potassium nitrate (K- NO After ignition of the composition by means of the ignition mixture disposed in a central ignition tube, a reaction of the composition set in with evolution of heat. The heat generated was 687 cal/g.
- a gas-producing composition comprising an aminoguanidine salt of at least one member selected from the group consisting of azotetrazole of the formula:
- II-N N and an oxygen-liberating additive or a gas-evolving additive selected from the group consisting of ammonium oxalate, urea, aminoguanidine, sugar and tartaric acid present in an amount up to 60 weight percent of the composition.
- an oxygen-liberating additive or a gas-evolving additive selected from the group consisting of ammonium oxalate, urea, aminoguanidine, sugar and tartaric acid present in an amount up to 60 weight percent of the composition.
- oxygen-liberating additive is a member selected from 5 the group consisting of inorganic chlorates, perchlorates and nitrates; nitroguanidine; guanidine nitrate; nitrocellulose; nitropolystyrene;
