    Nitrate is a nitrogen oxoanion formed by loss of a proton from nitric pal species present at pH It is a nitrogen oxoanion, a member of reactive nitrogen species and a monovalent inorganic anion. It is a conjugate base of a nitric acid. 9.

    Explosion Hazard from Ammonium Nitrate December Another explosion occurred in , during the manufacture of ammonium nitrate by a high temperature process. In this case, upset conditions allowed prolonged exposure of ammonium nitrate to temperatures up to °F under high pressure and low pH (acidic). Into this straw a well-blended mixture of IP and granular RNX is loaded. The bridgewire is positioned in the centre of the straw. On initiation, by passing a current through the nichrome wire, the heat of reaction from the ignition powder will ignite the combined IP and granular form of the RNX propellant, which ignites the propellant grain.

Composite Propellant Based on a New Nitrate Ester David A. Reese,*[a] Steven F. Son, [b]and Lori J. Groven 1 Introduction Many solid composite propellants are based on the oxidizer ammonium perchlorate (AP).

With its high oxygen content, good density, and gas-phase combustion products, AP sets a high standard for performance, stability, and low. Investigations into the self-ignition hazard of nitrate ester propellants ().Cited by: 2.

The burning rate can be represented in terms of the now standard exponential formula r = cp n with n taking different values over different ranges of pressure. For S.C. Cordite, n varies from below psi to a value of 1 ab psi. Most double base propellants of this simple type show a qualitatively similar behavior although as the burning rate is increased by raising the Cited by: 6.

Compositions and methods for increasing the storage life of a propellant grain by reducing the rate of decomposition of its nitrate ester components. A nitrate ester stabilizer is placed in a layer adjacent to a nonburning surface of the propellant grain.

Nitrocellulose, considered as the earliest nitrate ester widely utilized as the main component of energetic materials, can be employed in various fields owing to its several features such as toughness, compatibility with other compounds, flammability, good mechanical properties, etc.

Introduction The esters of nitric acid have long been used as explosives and propellants, and their thermal decomposition products and kinetics have been studied as a means to evaluate the thermal hazards of these compounds.

Each of the four underwent biolo- ä. Synthesis and reactions. Nitrate esters are typically prepared by condensation of nitric acid and the alcohol: For example, the simplest nitrate ester, methyl nitrate, is formed by reaction of methanol and nitric acid in the presence of sulfuric acid: CH 3 OH + HNO 3 → CH 3 ONO 2 + H 2 O.

This condensation is sometimes called "nitroxylation". The primary aging mechanism of nitrate ester propellants include several steps that begin with thethermal decomposition of the nitrate ester and lead to, if unmitigated, the evolution ofseveral gas speciesto include C02, and N These gases may lead to internal fissuring of the propellant or autocatalyticdecomposition and combustion.

Ignition of solid propellants and explosives involves an array of intricate physiochemical processes under energetic stimuli, and has been a subject of extensive research since In general, ignition models can be broadly divided into four categories: solid-phase (or reactive.

Nitrocellulose is the commercial term for cellulose nitrate, the nitric ester of cellulose. It is obtained by esterification of cellulose and nitric acid.
