Hygroscopic point at 25°C – 87%. Moderately soluble in hot acetone, methanol, ethanol, pyridine. t decay starts at about 150°C. Above 240°C it passes from rhombic to tetragonal modification. Transition heat 9 kJ / mol. t rapid decomposition 350-370°C (without melting). Density 1.952 g / cm3. The density of tetragonal modification existing above 240°C 1.76 g / cm3.
In the presence of combustible materials sensitivity to impact is significantly increased. For the first time ammonium perchlorate was obtained in 1831 (Serrulas) upon dissolution of ammonia in perchloric acid.
Decomposition catalysts: transition metal oxides, manganese and iron, copper chromite, ferrocene derivatives, iron acetylacetonate. Obtained by merging saturated solutions of sodium perchlorate and ammonium nitrate or neutralization of dilute chlorine K-Ty ammonia.
Quite toxic, able to penetrate through intact skin. In thermal decomposition, it releases toxic chlorine and hydrogen chloride.
Currently, it is widely used as an oxidizer in mixed rocket fuels and some EXPLOSIVES. Finds application in pyrotechnics: first of all – in fireworks and gas-generating structures.
