AMMONIUM SULFATE NITRATE COMPOSITION AND METHOD OF PRODUCTION OF SUCH COMPOSITION (VERSIONS) Russian patent published in 2006 - IPC C05C1/00 C05C3/00

Abstract RU 2279416 C2

FIELD: sulfate nitrate compositions used as fertilizers.

SUBSTANCE: proposed ammonium sulfate nitrate composition contains ammonium sulfate and (NH₄)₂SO₄·2 (NH₄NO₃)salt with at least 5%-mass of more dangerous (NH₄)₂SO₄·3(NH₄NO₃) salt and ammonium nitrate. Composition is obtained through reaction of ammonium sulfate with ammonium nitrate taken at mole ratio of from 0.9:1 to 1.1:1 in presence of small amount of water within limited temperature range; then, fast cooling is performed for hardening to avoid macroscopic separation of reaction products. Proposed composite material of ammonium sulfate and ammonium nitrate is used as fertilizer.

EFFECT: possibility of obtaining required levels of nitrate ions; high resistance to detonation, high density, high resistance to moisture.
