Hexaperchloratoaluminate
Hexaperchloratoaluminate is a polyatomic anion with the chemical formula . It is composed of six perchlorate groups ( or more precisely ) covalently bound to the central aluminium atom, resulting in the anion with net charge of –3. The six perchlorate groups are ligands of the central aluminium. This anion is a highly oxidizing and reactive complex, similar to other hexacoordinated aluminium complexes such as hexanitratoaluminate. The aluminium perchlorate salts formed with hexaperchloratoaluminate are of particular interest due to their potential uses as energetic materials. The series of hexaperchloratoaluminate salts includes lithium hexaperchloratoaluminate, ammonium hexaperchloratoaluminate, tetramethylammonium hexaperchloratoaluminate, and trinitronium hexaperchloratoaluminate. Each of these compounds possess unique properties and may have potential applications in areas such as rocket propellants, pyrotechnics, and other explosive-based technologies. Preparation Hexape ...

Perchlorate
A perchlorate is a chemical compound containing the perchlorate ion, , the conjugate base of perchloric acid (ionic perchlorate). As counterions, there can be metal cations, quaternary ammonium cations or other ions, for example, nitronium cation (). The term ''perchlorate'' can also describe perchlorate esters or covalent perchlorates. These are organic compounds that are alkyl or aryl esters of perchloric acid. They are characterized by a covalent bond between an oxygen atom of the ClO4 moiety and an organyl group. In most ionic perchlorates, the cation is non-coordinating. The majority of ionic perchlorates are commercially produced salts commonly used as oxidizers for pyrotechnic devices and for their ability to control static electricity in food packaging. Additionally, they have been used in rocket propellants, fertilizers, and as bleaching agents in the paper and textile industries. Perchlorate contamination of food and water endangers human health, primarily af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hexanitratoaluminate
Hexanitratoaluminate is an anion of aluminium and six nitrate groups with formula l(NO3)6sup>3− that can form salts called hexanitratoaluminates. Related compounds Hexaperchloratoaluminate l(ClO4)6sup>3− has perchlorate groups instead of nitrate, and is similarly sensitive to water. Pentanitratoaluminates have five nitrate groups. Tetranitratoaluminates have only four nitrate groups. Examples A known salt is potassium hexanitratoaluminate K3 l(NO3)6 Tetramethylammonium hexanitratoaluminate can be formed from tetramethylammonium chloride, aluminium chloride and dinitrogen tetroxide diluted with nitromethane Nitromethane, sometimes shortened to simply "nitro", is an organic compound with the chemical formula .

Nitronium Perchlorate
Nitronium perchlorate, NO2ClO4, also known as nitryl perchlorate and nitroxyl perchlorate, is an inorganic chemical, the Salt (chemistry), salt of the perchlorate anion and the nitronium ion, nitronium cation. It forms colorless monoclinic crystals. It is hygroscopic, and is a strong oxidizing and nitrating agent. It may become hypergolic in contact with organic materials. Nitronium perchlorate was investigated as an oxidizer in solid rocket propellants. Thomas N. Scortia filed for patent on such propellant in 1963, however, its reactivity and incompatibility with many materials hindered such use. Coating of nitronium perchlorate particles with ammonium nitrate, prepared in situ by passing of dry ammonia gas over the particles, was investigated, and a patent was awarded. The decomposition rate of nitronium perchlorate can be altered by doping with Polyvalency (chemistry), multivalent cations.

Aluminium Chloride
Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula . It forms a hexahydrate with the formula , containing six water molecules of hydration. Both the anhydrous form and the hexahydrate are colourless crystals, but samples are often contaminated with iron(III) chloride, giving them a yellow colour. The anhydrous form is commercially important. It has a low melting and boiling point. It is mainly produced and consumed in the production of aluminium, but large amounts are also used in other areas of the chemical industry. The compound is often cited as a Lewis acid. It is an inorganic compound that reversibly changes from a polymer to a monomer at mild temperature. Structure Anhydrous adopts three structures, depending on the temperature and the state (solid, liquid, gas). Solid has a sheet-like layered structure with cubic close-packed chloride ions. In this framework, the Al centres exhibit octahedral coordination geom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KClO4
Potassium perchlorate is the inorganic salt with the chemical formula K Cl O4. Like other perchlorates, this salt is a strong oxidizer when the solid is heated at high temperature, although it usually reacts very slowly in solution with reducing agents or organic substances. This colorless crystalline solid is a common oxidizer used in fireworks, ammunition percussion caps, and explosive primers, and is used variously in propellants, flash compositions, stars, and sparklers. It has been used as a solid rocket propellant, although in that application it has mostly been replaced by the more performant ammonium perchlorate. KClO4 has a relatively low solubility in water (1.5 g in 100 mL of water at 25 °C). Production Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride. This single precipitation reaction exploits the low solubility of KClO4, which is about 1/100 as much as the solubility of NaC ...

Al(NO3)3
Aluminium nitrate is a white, water-soluble salt of aluminium and nitric acid, most commonly existing as the crystalline hydrate, aluminium nitrate nonahydrate, Al(NO3)3·9H2O. Preparation Aluminium nitrate cannot be synthesized by the reaction of aluminium with concentrated nitric acid, as the aluminium forms a passivation layer. Aluminium nitrate may instead be prepared by the reaction of nitric acid with aluminium(III) chloride. Nitrosyl chloride is produced as a by-product; it bubbles out of the solution as a gas. More conveniently, the salt can be made by reacting nitric acid with aluminium hydroxide. Aluminium nitrate may also be prepared a metathesis reaction between aluminium sulfate and a nitrate salt with a suitable cation such as barium, strontium, calcium, silver, or lead. e.g. Al2(SO4)3 + 3 Ba(NO3)2 → 2 Al(NO3)3 + 3 BaSO4.

Nitrosonium Perchlorate
Nitrosyl perchlorate or nitrosonium perchlorate is the inorganic compound with the formula . A hygroscopic white solid, it is the salt of the nitrosonium cation with the perchlorate anion. It is an oxidant and strong electrophile, but has fallen out of use with the availability of the closely related salt nitrosonium tetrafluoroborate . Preparation Nitrosyl perchlorate was first produced in 1909 by passing dinitrogen trioxide gas into concentrated perchloric acid: : A standard laboratory preparation involves treating a mixture of nitric oxide and nitrogen dioxide with concentrated perchloric acid: : It can also be prepared by passing dinitrogen trioxide gas into a mixture of sodium perchlorate and sulfuric acid. A much purer product can be produced by reacting dichlorine heptoxide with anhydrous nitric acid. Structure The structure of NOClO4 has not been elucidated by X-ray crystallography. However, the Raman spectroscopy of NOClO4 suggests that nitrosyl perchlorate consists o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NH4ClO4
Ammonium perchlorate ("AP") is an inorganic compound with the formula . It is a colorless or white solid that is soluble in water. It is a powerful oxidizer. Combined with a fuel, it can be used as a rocket propellant called ammonium perchlorate composite propellant. Its instability has involved it in accidents such as the PEPCON disaster. Production Ammonium perchlorate (AP) is produced by reaction between ammonia and perchloric acid. This process is the main outlet for the industrial production of perchloric acid. The salt also can be produced by salt metathesis reaction of ammonium salts with sodium perchlorate. This process exploits the relatively low solubility of NH4ClO4, which is about 10% of that for sodium perchlorate.Helmut Vogt, Jan Balej, John E.
