Physical properties
Appearance: colorless orthorhombic crystals or white fine granular crystals.
Relative density: 1.725 (25℃).
Melting point: 169.6℃.
Decomposition temperature: Decomposes at 210℃ to release nitrous oxide and water vapor. If heated too hard, it will cause explosion.
Solubility: Soluble in water, methanol, ethanol, acetone and liquid ammonia, insoluble in ether.
Hygroscopicity: Strong, easy to agglomerate.
Chemical hazards: Heating may cause violent combustion or explosion, decomposition to generate toxic fumes, is a strong oxidant, reacts with acids, combustible substances and reducing substances
.
Chemical properties
Stability: It does not react to impact and friction at room temperature, but when there is an explosive or it is stored in a sealed container, it will cause an explosion due to the accumulated decomposition products (nitrogen dioxide and water vapor).
Oxidizing property: contact with organic matter, combustibles, sodium nitrite, sulfur, acid, etc. can cause explosion or combustion.
Thermal decomposition: different thermal decomposition temperatures will produce different decomposition products, and different gases and water will be generated at different temperatures
