Nitronium perchlorate

The oxygen content of NP is higher than that of most other crystaUine materials. Thus, its chemical potential as an oxidizer is high when combined with a fuel component. Since its theoretical density is 2220 kg m and its heat of formation is a positive value, r-33.6 kj moT, NP is an ideal material to serve as an oxidizer. However, N P is extremely hygroscopic and its hydrolysis forms nitric acid and perchloric acid according to  [Pg.72]

Moreover, NO2 is formed by the thermal decomposition of NP at about 360 K, a temperature too low to permit its use as a practical oxidizer ingredient. [Pg.72]


Nitronium salts are colourless, crystalline and very hygroscopic nitronium perchlorate and sulphate are unstable and liable to spontaneous decomposition, whereas nitronium tetrafluoroborate and other complex fluoro-salts are relatively stable. [Pg.61]

A final category of encapsulating materials consists of reaction products of the nucleus material and a reagent. For example, pellets of nitronium perchlorate have been encapsulated in shells of the less reactive amm perchlorate (AP) by exposing the pellets to ammonia gas. The fragile AP shells were usually further protected by a top-coating of A1 or a polymer film (Ref 2). The most familiar example of this process is the natural one wherein A1 powders (or articles) become coated with a protective coating of A1 oxide thru exposure to atmospheric air... [Pg.142]

Microencapsulation is usually attempted because a proposed ingredient is too reactive or too sensitive to withstand exposure to other ingredients nr tQ the environment. For example, the very energetic oxidizer nitronium perchlorate (NP) cannot be mixed directly into a proplnt or expl formulation because of its extreme reactivity. It is actually a solid anhydride between nitric and perchloric acids, and even traces of moisture hydrolyze the surface layers to free coned nitric... [Pg.142]

Nitric Acid. Anhyd perchloric ac reacts with 100% nitric ac to form nitronium perchlorate (02N+C104-) (see below) and hydroilium perchlorate (see above under hydrates) (Ref 16) Ozone. Anhyd perchloric ac reacts with ozone when irradiated with light of wavelength 254my to give HOOCIO3, which is unstable and decomps to 0 and chloric ac (Ref 25)... [Pg.619]

It is prepd by a similar procedure as that used for the ammonium salt using nitronium perchlorate, and has similar props (Ref 10) Uses, (see under Perchlorate Explosives and Propellants)... [Pg.623]

Preparation. It was first prepd in an impure form by Hantzsch who isolated a ciyst solid when anhyd nitric and perchloric acids were mixed. He reported the solid to be 0N(0H)2+.C104 (Ref 2), but later work by Goddard and coworkers showed this solid to be a mixt of nitronium perchlorate and perchloric ac mono-hydrate (Ref 4). It is best prepd by distilling anhyd perchloric ac onto an excess of dry dinitrogen pentoxide at -80°, the mixt allowed to warm to room temp, and the mixt pumped under vacuum for 2 days to remove volatiles. The residue was shown by analysis to be a mixt of 89 mole % nitronium perchlorate and 11 mole %... [Pg.640]

Uses. Attempts have been made to use nitronium perchlorate as a high energy propint ingredient, but incompatibility with other ingredients and hygroscopicity have combined to hinder such use (Ref 9)... [Pg.640]

Composite proplnts, which are used almost entirely in rocket propulsion, normally contain a solid phase oxidizer combined with a polymeric fuel binder with a -CH2—CH2— structure. Practically speaking AP is the only oxidizer which has achieved high volume production, although ammonium nitrate (AN) has limited special uses such as in gas generators. Other oxidizers which have been studied more or less as curiosities include hydrazinium nitrate, nitronium perchlorate, lithium perchlorate, lithium nitrate, potassium perchlorate and others. Among binders, the most used are polyurethanes, polybutadiene/acrylonitrile/acrylic acid terpolymers and hydroxy-terminated polybutadienes... [Pg.886]

The influence of metal type on the specific impulse of propints has been described previously in this article (Table 16). The max theoretical specific impulse and density impulses (ISp x p ) for the oxidizers AN, AP and hydrazinium nitrate with 15 weight percent -fCH2)- binder have been calculated for various fuels (Ref 24). These data are in Tables 49-51. The ISp performance of nitronium perchlorate, lithium perchlorate and potassium perchlorate and metallized fuels with 4CH2>- binder are given in Table 52 (Ref 43)... [Pg.922]

The explosively unstable behaviour of stored nitronium perchlorate is attributed to the formation of small equilibrium concentrations of the isomeric covalent nitryl perchlorate ester (below). [Pg.1384]

The above book [1] deals, in 26 chapters in 5 sections, with theoretical and practical aspects of the use and safe handling of powerful oxidants and their complementary reactive fuels. Materials include nitrogen pentaoxide, perfluoroam-monium ion and salts, nitronium tetrafluoroborate, hydrazinium mono- and diperchlorates, nitronium perchlorate, tricyanomethyl compounds, difluoramine and its alkyl derivatives, oxygen difluoride, chlorine trifluoride, dinitrogen tetraoxide, bromine trifluoride nitrogen fluorides, and liquid ozone-fluorine system. [Pg.360]

A number of other compounds have been considered as additives to HN03 to improve its properties and/or performance capabilities. Among the more important are N2Or NO0CIO4 (nitronium perchlorate), and HCIO4. While each of these systems theoretically provides increased performance, their use presents some technical and operational problems. Only careful consideration of the magnitude of these problems vs. potential benefits and alternatives can resolve the question of their role as advanced oxidizers. [Pg.333]

Ammonium perchlorate satisfies most of the requirements and is used most widely in composite propellants all over the world. The greatest advantage of AP is the immense experience and vast information on AP-based propellants available over several decades which impart more confidence in this oxidizer. Other non-metallic oxidizers have also been investigated in detail but have not been found suitable for use for one reason or the other. Nitronium perchlorate (NP) which has positive heat of formation and highly favorable oxygen balance was also... [Pg.234]
