1. Basic Info
Name: Sodium perchlorate monohydrate
Alias: NaClO4·H2O
CAS No.:7791-07-3
Molecular Formula:Na1Cl1O4·H2O
Molecular Weight:140.46
2. Physical & Chemical Properties
Physical Properties
- Appearance: Colorless transparent orthorhombic crystal, odorless
- Solubility: Extremely soluble in water; soluble in methanol, ethanol, acetone; slightly soluble in ethyl acetate
- Melting Point: Dehydrates at ~130℃; anhydrous salt melts at 468℃
- Density(20℃):2.02 g/cm3
- Hygroscopy: Strongly hygroscopic, easily absorbs moisture in air
- Crystal water: Contains 1 molecule of crystal water, loses crystal water when heated above 120℃ to form anhydrous NaClO4
- Aqueous solution: Neutral, colorless transparent liquid
Chemical Properties
- Structure: Ionic compound composed of Na1+ and Cl1O41- perchlorate anion
- Strong oxidizing property: Perchlorate ion has high oxidation capacity; mixed with organics, sulfur, phosphorus, metal powder will cause combustion and explosion under friction, impact or heating
- Dehydration reaction: Heating to 120–140℃ removes crystal water to get anhydrous sodium perchlorate
- Metathesis reaction: Reacts with potassium salt, ammonium salt to generate potassium perchlorate, ammonium perchlorate precipitates
- Thermal decomposition: Anhydrous salt decomposes above 480℃ to release oxygen, sodium chloride
- Acid-base stability: Stable in neutral and alkaline environment; concentrated strong acid generates perchloric acid
- Compatibility: Forbidden to mix with reducing agents, combustible materials, organic solvents, metal powders
3. Main Application Fields
1. Chemical Raw Material (Core Application)
