Triethyl phosphate finds it major applications in plastics industry as a flame retardant, plasticizer and carrier, where it is available in the matrix. A further 10 to 20 % are used in other industrial branches as a solvent, plasticizer, flame retardant or intermediate for the production of pharmaceuticals, and lacquers. Triethyl phosphate is a useful synthetic intermediate used in the synthesis of mesoporous spheres of metal oxides and phosphates. It is also used as an industrial catalyst employed in ketene synthesis where the compound is hydrolyzed, as a polymer resin modifier, as a solvent, a car paint repairing product and as flame retarderThis Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Triethyl phosphate (TEP) is a fatty acid that has been shown to exhibit chronic toxic effects in a model system. TEP is known to be used as an additive in water-based paints and varnishes, which may lead to exposure through inhalation or skin contact. The Langmuir adsorption isotherm has been used to assess the TEP solubility in water at different temperatures. In addition, the toxicity of TEP has been studied using electrochemical impedance spectroscopy. This technique was also used for the determination of triethyl phosphate content in different media, including sodium succinate, analytical method and sodium citrate. The LC-MS/MS method was used for the identification of triethyl phosphate in water vapor samples.

Applications Triethyl Phosphate is a useful synthetic intermediate. It was used in the synthesis of mesoporous spheres of metal oxides and phosphates. It was also used to prepare α,β-unsatd. tricyclic enones via an intramolecular Horner-Wadsworth-Emmons cyclization. Flame Retardant References Dong, A., et al.: J. Am. Chem.
