2,4,6-Tris(trinitromethyl)-1,3,5-triazine
2,4,6-Tris(trinitromethyl)-1,3,5-triazine is a chemical compound that is a derivative of triazine first prepared in 1995. It is synthesized by destructive nitration of 2,4,6-tricarboxyl-1,3,5-triazine. It is noteworthy for having more nitro groups than it does carbon atoms, thus potentially being useful as an oxygen source, or added to oxygen-poor explosives to increase their power. Derivatives have been prepared by nucleophilic displacement of the nitro groups with azide and hydrazine Hydrazine is an inorganic compound with the chemical formula . It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly hazardous unless handled in solution as, for example, hydraz ....

4,4’-Dinitro-3,3’-diazenofuroxan
4,4’-Dinitro-3,3’-diazenofuroxan (DDF) is a powerful experimental high explosive, with performance comparable to that of other high-density high-explosives such as octanitrocubane. It is synthesised by oxidative coupling of 4-amino-3-(azidocarbonyl) furoxan followed by Curtius rearrangement and further oxidation.

Hexanitrohexaazaisowurtzitane
Hexanitrohexaazaisowurtzitane, also called HNIW and CL-20, is a polycyclic compound, polycyclic nitroamine explosive with the formula . It has a better Redox, oxidizer-to-fuel ratio than conventional HMX or RDX. It releases 20% more energy than traditional HMX-based propellants. History and use In the 1980s, CL-20 was developed by the Naval Air Weapons Station China Lake, China Lake facility, primarily to be used in propellants. While most development of CL-20 has been fielded by the Thiokol, Thiokol Corporation, the US Navy (through Office of Naval Research, ONR) has also been interested in CL-20 for use in rocket propellants, such as for missiles, as it has lower observability characteristics such as less visible smoke. Thus far, CL-20 has only been used in the AeroVironment Switchblade 300 “kamikaze” drone, but is undergoing testing for use in the Lockheed Martin [LMT] AGM-158C Long Range Anti-Ship Missile (LRASM) and AGM-158B Joint Air-to-Surface Standoff Missile-Exten ...

Cyanuric Triazide
Cyanuric triazide (C3N12 or (NCN3)3) is described as an environmentally friendly, low toxicity, and organic primary explosive with a detonation velocity of about 7,300 m s−1 and a autoignition temperature of 205 °C. Structure The cyanuric triazide molecule exists as a planar triskelion with molecular point group ''C''3h. The 1,3,5-triazine (or cyanuric) ring consists of alternating carbon and nitrogen atoms with C–N bond lengths of 1.334 to 1.336 Å. The distance from the center of the ring to each ring carbon atom is 1.286 Å, while the corresponding distance to ring nitrogens is 1.379 Å. Azide groups are linked to the carbon atoms on the cyanuric ring by single bonds with an interatomic distance of 1.399 Å. Synthesis Cyanuric triazide can be synthesized via the nucleophilic aromatic substitution of cyanuric trichloride with an excess of sodium azide in heated acetone. The white crystals can then be purified via recrystallization from − ...

Octanitrocubane
Octanitrocubane (molecular formula: C8(NO2)8) is a proposed high explosive that, like TNT, is shock-insensitive (not readily detonated by shock). The octanitrocubane molecule has the same chemical structure as cubane (C8H8) except that each of the eight hydrogen atoms is replaced by a nitro group (NO2). As of 1998, octanitrocubane had not been produced in quantities large enough to test its performance as an explosive. It is, however, not as powerful an explosive as once thought, as the high-density theoretical crystal structure has not been achieved. For this reason, heptanitrocubane, the slightly less nitrated form, is believed to have marginally better performance, despite having a worse oxygen balance. Octanitrocubane is thought to have 20–25% greater performance than HMX (octogen). This increase in power is due to its highly expansive breakdown into CO2 and N2, as well as to the presence of strained chemical bonds in the molecule which have stored potential energy. In a ...

Nitro Compound
In organic chemistry, nitro compounds are organic compounds that contain one or more nitro functional groups (). The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally. The nitro group is also strongly electron-withdrawing. Because of this property, bonds alpha (adjacent) to the nitro group can be acidic. For similar reasons, the presence of nitro groups in aromatic compounds retards electrophilic aromatic substitution but facilitates nucleophilic aromatic substitution. Nitro groups are rarely found in nature. They are almost invariably produced by nitration reactions starting with nitric acid. Synthesis Preparation of aromatic nitro compounds Aromatic nitro compounds are typically synthesized by nitration. Nitration is achieved using a mixture of nitric acid and sulfuric acid, which produce the nitronium ion (), which is the electrophile: + The nitration product produced on the largest scale, by f ...

Azide
In chemistry, azide (, ) is a linear, polyatomic anion with the formula and structure . It is the conjugate base of hydrazoic acid . Organic azides are organic compounds with the formula , containing the azide functional group. The dominant application of azides is as a propellant in air bags. Preparation Sodium azide is made industrially by the reaction of nitrous oxide, with sodium amide in liquid ammonia as solvent: : Many inorganic azides can be prepared directly or indirectly from sodium azide. For example, lead azide, used in detonators, may be prepared from the metathesis reaction between lead nitrate and sodium azide. An alternative route is direct reaction of the metal with silver azide dissolved in liquid ammonia. Some azides are produced by treating the carbonate salts with hydrazoic acid. Bonding Azide is isoelectronic with carbon dioxide , cyanate , nitrous oxide , nitronium ion , molecular beryllium fluoride and cyanogen fluoride FCN. Per ...

Hydrazine
Hydrazine is an inorganic compound with the chemical formula . It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (). Hydrazine is mainly used as a foaming agent in preparing Polymeric foam, polymer foams, but applications also include its uses as a precursor (chemistry), precursor to pharmaceuticals and agrochemicals, as well as a long-term storable propellant for in-outer space, space spacecraft propulsion. Additionally, hydrazine is used in various rocket propellant, rocket fuels and to prepare the gas precursors used in airbags. Hydrazine is used within both nuclear and conventional electrical power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion. , approximately 120,000 tons of hydrazine hydrate (corresponding to a 64% solution of hydrazine in water by weight) we ...

Triazines
Triazines are a class of nitrogen-containing heterocycles. The parent molecules' molecular formula is . They exist in three isomeric forms, 1,3,5-triazines being common. Structure The triazines have planar six-membered benzene-like ring but with three carbons replaced by nitrogens. The three isomers of triazine are distinguished by the positions of their nitrogen atoms, and are referred to as 1,2,3-triazine, 1,2,4-triazine, and 1,3,5-triazine. Other aromatic nitrogen heterocycles are pyridines with one ring nitrogen atom, diazines with 2 nitrogen atoms in the ring, triazoles with 3 nitrogens in a 5-membered ring, and tetrazines with 4 ring nitrogen atoms. Uses Melamine A well known triazine is melamine (2,4,6-triamino-1,3,5-triazine). With three amino substituents, melamine is a precursor to commercial resins. Guanamines are closely related to melamine, except with one amino substituent replaced by an organic group. This difference is exploited in the use of guanamine ...
