2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: White colorless crystalline powder
- Odor: Slight acidic odor
- Solubility: Freely soluble in water; soluble in methanol, ethanol; slightly soluble in glycerol; insoluble in ether, benzene
- pH (10% aqueous solution): 3.0 ~ 4.0, weak acid
- Melting Point: Decompose at 151 °C
- Hygroscopy: Hygroscopic, easy to absorb moisture and agglomerate under high humidity
- Crystal Character: Orthorhombic crystal, good fluidity when dry
2.2 Chemical Properties
- Reducing Property: Strong reducing agent, reduces Fe3?, Cu2?, Au3? and other metal ions to low-valent metals
- Oximation Reaction: Reacts with aldehyde, ketone carbonyl group to generate oxime derivatives, core reaction in fine chemical synthesis
- Thermal Decomposition: Decomposes above 150°C, releases nitrogen oxide, hydrogen chloride toxic gas; risk of violent decomposition under high temperature impact
- Acid-Base Stability: Stable in acidic environment; reacts with strong alkali to release free hydroxylamine gas
- Compatibility: Incompatible with strong oxidants, alkali, nitrite, easily trigger exothermic reaction or explosion risk
