Deliquescence, 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 کاملRearrangements of Ammonium Nitrate Cluster Ions with High Internal Energy
Sputtering of condensed-phase ammoniumnitrate yields an extensivedistribution of negative cluster ions of the form [(NH4N03),N03]-, n 2 3. Collision-induced dissociation of mass-selected cluster ions suggests that the first two members of the series, n = 1 and n = 2, are missing because the ions rearrange to lose one or more ammonia molecules. Gradient-corrected density-functional calculations ...
متن کاملEPR Study of Ammonium Nitrate Doped with Copper(II) Ions
This work is devoted to a study of the structural changes in a single crystal of ammonium nitrate, NH4NO3, doped with copper(II) cations by electron paramagnetic resonance. Ammonium nitrate crystallizes at atmospheric pressure in several polymorphic forms, phase VII → V → IV → III → II → I → melt, with transition temperatures of 103 K, 255 K, 305 K, 357 K, 398 K, and 443 K, respectively. The ai...
متن کاملBis(pyridin-2-ylmethyl)ammonium nitrate
In the title compound, C12H14N3 (+)·NO3 (-), the mononitrate of protonated bis-(pyridin-2-ylmeth-yl)amine, the least-squares planes defined by the non-H atoms of the two aromatic moieties inter-sect at an angle of 7.91 (6)°. In the crystal, N-H⋯N, N-H⋯O and C-H⋯N hydrogen bonds, as well as C-H⋯O contacts, connect the entities into a three-dimensional network. The shortest centroid-centroid dist...
