Thermochemistry of ammonium nitrate, NH₄NO₃, in the gas phase.
Hildenbrand and co-workers have shown recently that the vapor above solid ammonium nitrate includes molecules of NH₄NO₃, not only NH₃ and HNO₃ as previously believed. Their measurements led to thermochemical values that imply an enthalpy change of D₂₉₈ = 98 ± 9 kJ mol⁻¹ for the gas-phase dissociation of ammonium nitrate into NH₃ and HNO₃. Using updated spectroscopic information for the partitio...

متن کاملDeliquescence, Efflorescence, and Water Activity in Ammonium Nitrate and Mixed Ammonium Nitrate/Succinic Acid Microparticles
We have investigated the thermodynamics and kinetics of ammonium nitrate/water and mixed ammonium nitrate/succinic acid/water microparticles. The water activity of ammonium nitrate microparticles is determined as a function of composition down to 12% relative humidity by accounting for the rapid evaporation of ammonia and nitric acid. Both the observed deliquescence and water activities for amm...
متن کاملQuantification of Ammonium Sulphate Nitrate (ASN) fertilizers
This paper shows a simple procedure for the quantification of industrial and laboratory samples of Ammonium Sulphate-Nitrate fertilizers (ASN) based on a Rietveld fit from X-ray powder diffraction profiles. The Rietveld fit is performed by means of the structural models of the double salts 2NH4NO3·(NH4)2SO4 and 3NH4NO3·(NH4)2SO4, previously reported by the authors. The proposed method demonstra...
متن کاملThe Characterization of Ammonium Nitrate Mini-Prills
Ammonium nitrate (AN) is commonly used as a fertilizer and is the fundamental ingredient of industrial explosives [1]. It has been observed that one of the most important factors that affect explosive performance of ammonium nitrate and fuel oil is the prills volume of porosity. The large amount of porosity identified in explosive grade AN prills allows for an absorption rate between 12 and 16 ...
