Ammoniumperchlorat

Molecular formula NH4ClO4 Formuladecomposition heat disproportionation 4NH4ClO4 = = 4NH3 ↑ +2 Cl2 ↑ +7 O2 ↑ +2 H2O or 2NH4ClO4 = = N2 ↑ + Cl2 ↑ +4 H2O +2 O2 ↑ (the temperature at different decomposition products are also different) Type volume of 117.49 Density 1.95g/cm3 Properties colorless orthorhombic crystal. Situation dissolved water-soluble [10.74g (0 ) 42.45g (85 )], slightly soluble in alcohol, insoluble in ether. There deliquescence. Risk High risk of collision and with the organic matter, as well as agents, flammable substances such as sulfur, phosphorus, and metal powder mixed and with the acid burn caused by contact with a risk of explosion. Uses is a strong oxidizing agent. Organic matter or combustible materials on the ground was an explosion. For the system of explosives, fireworks, and used as analytical reagent and so on. Caused by magnesium aluminum oxide. Triggering a large number of ammonium perchlorate decomposition of gases, used in rocket. Manufacture of ammonium perchlorate explosives, anti-hail engraver agents and artificial agents. Source preparation or by the high-sodium chlorate solution and the role of ammonium chloride solution derived. Note Store in a cool, dry warehouse in the construction of non-combustible materials, with combustible materials, sulfur, carbon materials, fine metal powders, organic substances, or other oxides, as well as inorganic acid isolation easy storage and transportation. Can not be easily stored in the fire place, to avoid the heat to prevent moisture, handling, the lightly armed light unloading, do not slam.Table one SpecItemsIndexsA GradeB GradeC GradeD GradeThe mass fraction of ammonium perchlorate (in NH4ClO4),%≥99.5Material mass fraction (in NaCl),%≤0.1Chlorate mass fraction (in NaClO3),%≤0.02Bromate mass fraction (in NaBrO3),%≤0.004Chromate mass fraction (in K2CrO4),%≤0.015Mass fraction of iron (Fe),%≤0.001Mass fraction of water-insoluble,%≤0.02Sulfate ash mass fraction,%≤0.25pH value4.35.8Thermal Stability (177 ± 2 ), h ≥ 3≥3Sodium dodecyl sulfate mass fraction,%≤0.02Total water mass fraction,%≤0.05The surface of the water mass fraction,%≤0.06
