Phosphoric acid, tris(2-ethylhexyl) ester

Description:

Phosphoric acid, tris(2-ethylhexyl) ester, commonly known as trioctyl phosphate (TOP), is an organophosphate compound characterized by its use as a plasticizer and flame retardant in various applications. It is a colorless to pale yellow liquid with a slightly oily texture and a mild odor. This compound is soluble in organic solvents but has limited solubility in water, which makes it useful in enhancing the flexibility and durability of plastics. Its chemical structure features three 2-ethylhexyl groups attached to a phosphate backbone, contributing to its hydrophobic properties. Trioctyl phosphate is also known for its ability to act as a solvent for certain metal ions and is utilized in the extraction of metals in hydrometallurgy. Additionally, it exhibits low volatility and thermal stability, making it suitable for high-temperature applications. However, it is important to handle this substance with care, as it may pose environmental and health risks if not managed properly.
