trietilfoszfátot

Trietilfoszfát, often abbreviated as TEP, is a chemical compound with the formula (C2H5O)3PO. It is an organophosphate ester and is a colorless liquid with a mild, fruity odor. TEP is soluble in many organic solvents and has limited solubility in water. It is produced by the esterification of phosphoric acid with ethanol.

TEP finds application as a plasticizer, particularly in cellulose nitrate and vinyl polymers, to increase their flexibility and durability. It is also used as a flame retardant additive in various materials, including plastics, textiles, and coatings, where it acts by promoting char formation and reducing the release of flammable gases. In some formulations, it can function as a solvent or a carrier for other additives.

Historically, TEP has been investigated for use in certain niche applications, though its widespread use is primarily as an industrial additive. Its environmental fate and toxicological profile are important considerations for its handling and disposal. While generally considered to have low acute toxicity, prolonged or high-level exposure may pose health risks. Regulatory bodies often set guidelines for its presence in consumer products and its release into the environment.
