What is Iron Chloride Hexahydrate CAS 10025-77-1?
Chemical labeling
Molecular formula: FeCl₃·6H₂O or Cl₃FeH₁₂O₆
Molecular weight: 270.3 g/mol
Appearance: Yellowish-brown crystals or blocky solids, odorless, with astringent taste.
Melting point: 37℃ (Deliquesces into a reddish-brown liquid).
Boiling point: 280-285℃.
Density: 1.82 g/cm³ (20℃).
Solubility and stability
Solubility
It is highly soluble in water (920 g/L, 20℃), and the aqueous solution is strongly acidic (pH 1.8, 10g/L).
Soluble in ethanol, ether, acetone and glycerol; Insoluble in benzene.
Stability
It has strong hygroscopicity and is prone to deliquescence in the air.
Contact with strong oxidants and alkali metals (such as sodium and potassium) may form explosive mixtures.
It may be reduced to ferrous compounds when exposed to light or heat.
Iron Chloride Hexahydrate CAS 10025-77-1 Use
Water treatment
Flocculant: Highly efficient in removing suspended solids and colloids, suitable for pH 6.0-11.0 (optimal 6.0-8.4), dosage 5-100 mg/L, fast sedimentation speed and not affected by temperature.
Pollutant degradation: Strong oxidizing properties can decompose organic pollutants (such as phenol and cyanide).
Industrial manufacturing
Etching agent: It is used for the corrosion processing of printed circuit boards and metal signs (such as copper and stainless steel).
Catalyst: Promotes organic synthesis reactions (such as olefin polymerization and esterification reactions).
Dyes and pigments: Mordants and oxidants, used in printing and dyeing, and the production of fluorescent dyes.
Other fields
Nutritional fortifier: Added to infant formula and weaned milk products (it needs to be converted into whey iron to reduce acidity).
Analytical reagents: For the determination of arsenic, lithium, selenium, serum cholesterol, etc.
New energy materials: Iron source for lithium iron phosphate, the cathode material of lithium-ion batteries.
