Stabilizing granulated ammonium nitrate. Vovkotrub, N. F.; Kopilevich, V. A.; Rusin, G. G.; Shchegrov, L. N.; Beglov, V. M.; Beglov, B. M. (Ukrainian Agricultural Academy, USSR). U.S.S.R. SU 1063799 A1 30 Dec 1983 From: Otkrytiya, Izobret., Prom. Obraztsy, Tovarnye Znaki 1983, (48), 95-6. (Russian). (Union of Soviet Socialist Republics).Several substances with their cas registry numbers 10421-48-4 and 10028-22-5 may be metioned in this study. CODEN: URXXAF. CLASS: IC: C05C001-02. APPLICATION: SU 82-3496031 17 Sep 1982. DOCUMENT TYPE: Patent CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) Section cross-reference(s): 49 Granulated NH4NO3 is stabilized by adding to it a melt of an Fe-contg. additive. To avoid III-IV modification transitions while simultaneously improving the physicomech. and agrochem. properties of the fertilizer, a trivalent Fe salt is used as the additive. In addn., polyphosphoric acid or NH4 polyphosphate is added, with the polyphosphate:Fe salt ratio being 1:0.1-0.5. Fe(NO3)3, Fe2(SO4)3, or ferric citrate [28633-45-6] may be used as the Fe salt, and the polyphosphonic acid or NH4 polyphosphate should have >80% P2O5 in the polyanions. The trivalent Fe and polyphosphate compds. are added in an amt. of 1-4% of the wt. of the NH4NO3. .
