C12H18O4P

C12H18O4P is the molecular formula for several chemical compounds, most notably triethyl phosphate. Triethyl phosphate is an organophosphate ester. It is a colorless liquid with a mild odor. This compound is primarily used as a flame retardant and a plasticizer. It can also be found in some cleaning products and as a solvent.

Triethyl phosphate is synthesized through the reaction of phosphorus oxychloride with ethanol. The chemical formula indicates that each molecule contains 12 carbon atoms, 18 hydrogen atoms, 4 oxygen atoms, and 1 phosphorus atom. Its physical properties include a boiling point of approximately 215 degrees Celsius and a density slightly greater than water.

In industrial applications, triethyl phosphate's flame retardant properties are valuable in materials like polyurethane foams and plastics. As a plasticizer, it can increase the flexibility and durability of polymers. While generally considered to have low toxicity, exposure to high concentrations may cause irritation to the skin, eyes, and respiratory tract. Environmental considerations regarding its persistence and potential aquatic toxicity are also subjects of study.
