Standard enthalpy of solution of ammonium nitrate in water at 298 K

Standard enthalpy of solution of ammonium nitrate in water at 298 K. Medvedev, V. A.; Efimov, M. E.; Cerutti, Paul J.; McKay, Robert M.; Johnson, Lawrence H.; Hepler, Loren G. (Inst. High Temp., Moscow, USSR). Thermochim. Acta, 23(1), 87-92 (English) 1978. CODEN: THACAS. ISSN: 0040-6031. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Calorimetric measurements were made of the enthalpy of soln. of NH4NO3(c,IV) [6484-52-2] in water at 298 K, where (c, IV) indicates the crystal form of NH4NO3 that is stable from 256 to 305 K. The std. enthalpy of soln. of NH4NO3 (c, IV) in water at 298.15 K is DH0 = 25.41 kJ mol-1.

ISSN: 0307-0492. DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 19, 49 Investigations of 3 explosion accidents have shown that urea [57-13-6]-NH4NO3 [6484-52-2] fertilizer solns. contg. 28-34% N are of themselves safe with resp. to thermal and detonation stability. In fires, however, partial confinement in the insulation may lead to a detonation and therefore should be avoided. Recommendations for safe handling and transport of these solns. are given.
