Product Name	Tri-n-octylamine (TOA) (Tertiary Amine Extractant)
CAS NO.	1116-76-3
Formula & Weight	C24H51N (MW: 353.67)
Chemical Structure
Technical Specifications	Appearance: Colorless to pale yellow transparent liquid Purity (GC): ≥ 95.0% / 97.0% Total Amine Value: 151.0 - 159.0 mg KOH/g Color (APHA): ≤ 60 Moisture: ≤ 0.3% Density (20°C): ~0.81 g/cm³ Solubility: Soluble in non-polar organic solvents, insoluble in water
Key Applications	A powerful hydrophobic amine extractant and phase transfer catalyst: 1. Hydrometallurgy (Metal Extraction) Acid Extraction: Highly effective for the extraction of organic acids (Citric, Succinic) and inorganic acids (HCl, H2SO4). Rare & Precious Metals: Widely used to recover Uranium, Cobalt, Nickel, and Rare Earth Elements from acidic leach solutions. Wastewater Treatment: Removes heavy metal ions from industrial effluents. 2. Chemical Synthesis Phase Transfer Catalyst: Facilitates reactions between immiscible phases in organic synthesis. Intermediate: Precursor for manufacturing quaternary ammonium salts and surfactants.
Packaging & Handling	Standard: Iron Drum / IBC Tank. Storage: Store in a cool, dry, well-ventilated area. Keep container tightly closed to prevent amine oxidation.
