78-40-0
Product name: Triethyl Phosphate
English alias: TEP; Ethyl phosphate; Phosphoric acid triethyl ester
CAS: 78-40-0
Molecular formula: C6H15O4P
Appearance: Colourless transparent liquid
Package: 200kg/drum
Triethyl phosphate appears as a colorless liquid with a mild odor and is slightly soluble in water, but will gradually hydrolyze as the temperature rises. Triethyl phosphate is easily soluble in various organic solvents such as ethanol, ether, and benzene.
Test Item | Unit | Specification |
Purity | % | ≥ 99.0 |
Moisture | % | ≤ 0.1 |
Acidity (as H₃PO₄) | % | ≤ 0.01 |
Refractive Index (20°C) | - | 1.403 - 1.405 |
Density (20°C) | g/cm³ | 1.065 - 1.075 |
Color (APHA) | - | ≤ 20 |
1.Flame Retardant: Triethyl Phosphate used in unsaturated polyesters, epoxy resins, PVC, and other polymers to improve flame resistance.
2.Plasticizer: Triethyl Phosphate enhances flexibility and processing of plastics and rubber products.
3.Solvent: Triethyl Phosphate acts as a solvent for cellulose acetate, resins, and oils.
4.Chemical Intermediate: Triethyl Phosphate used in the synthesis of pesticides, pharmaceuticals, and other organic compounds.
5.Catalyst: serves as a catalyst in transesterification and other reactions.
6.Stabilizer: used in hydraulic fluids and lubricant formulations.
Triethyl Phosphate is generally considered to have low acute toxicity. However, it may cause irritation to the skin, eyes, and respiratory system. Proper personal protective equipment (PPE) such as gloves and goggles is recommended during handling. It is not classified as a carcinogen, but prolonged exposure should be avoided. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
Store in a cool, dry, well-ventilated area.
Keep container tightly closed.
Avoid contact with strong oxidizing agents.
Recommended storage temperature: below 30°C.
Keep away from heat, sparks, and open flames.
Triethyl Phosphate is typically supplied in:
200 kg steel drums
1000 kg IBC totes
All packages are compliant with international transport regulations for hazardous chemicals (if applicable). Proper labeling and documentation are provided for safe shipping.
