  • Compatibility of Ammonium Nitrate with Monomolecular Explosives. 2. Nitroarenes
    The Journal of Physical Chemistry, 1994
    Co-Authors: Jimmie C. Oxley, James L. Smith, Wen Wang

    Abstract:

    Ammonium Nitrate/fuel mixtures are widely used commercially; however, for military application it is often deemed necessary to enhance their performance by addition of conventional organic explosives. It is unreasonable to assume that such mixtures would retain the same thermal properties as the parent Ammonium Nitrate formulations. This paper presents a study of the thermal stability of such mixtures. Mixtures of Ammonium Nitrate and nitroaromatic compounds in various ratios have been decomposed isothermally in the temperature range 216-360 o C. The thermal decomposition kinetics of both Ammonium Nitrate and the nitroarenes have been followed by liquid chromatography. Markedly enhanced decomposition of both Ammonium Nitrate and the nitroarenes was observed

  • Compatibility of Ammonium Nitrate with Monomolecular Explosives. 1
    The Journal of Physical Chemistry, 1994
    Co-Authors: Jimmie C. Oxley, James L. Smith, Wen Wang

    Abstract:

    The thermal stability of mixtures of Ammonium Nitrate with a variety of organic explosives was examined over the temperature range 170 to 320 o C. Although the overall stability of the one-to-one mixtures was studied, the emphasis was comparison of the thermal stability (isothermal rate constants) of the individual components in the mixture with the neat species. It was found that Nitrate esters, PETN and nitrocellulose, nitramines, RDX and HMX, and nitroarenes, TNT and trinitroaniline, destabilized Ammonium Nitrate. In turn, Ammonium Nitrate, or its decomposition products, destabilized the organic explosives to varying degrees. For RDX and PETN the destabilization was slight

  • Study on Thermal Stability of Ammonium Nitrate
    Journal of Zhengzhou University of Technology, 2003
    Co-Authors: Wang Guang-long

    Abstract:

    Mechanism and influence factors on thermal decomposition of Ammonium Nitrate between 100～150 ℃ are studiedEffect of stabilizing agents and activator is emphatically analyzedThe thermal stability of system is reduced by activators,such as moisture,nitric acid,sulfuric acid and phosphoric acidCompared with pure Ammonium Nitrate,when 05%(wt%) of the activator in the system,the induction time could be decreased by 50%Adding 3% of zinc oxide or aluminum hytroxide,the decomposition reaction might be effectively inhibitedBut for calcium carbonate or potassium chloride,to achieve the same effect needs 15%Urea is a suitable stabilizing agent of Ammonium NitrateDecomposition at 130 ℃ is stopped when there is 1% of urea in the system 
