triphenyylfosfaatti

Triphenyylfosfaatti, often abbreviated as TPP, is an organophosphorus compound with the chemical formula (C₆H₅)₃PO. It is a colorless, crystalline solid that is soluble in many organic solvents but insoluble in water. TPP is widely used as a plasticizer, a flame retardant, and a solvent in various industrial applications.

As a plasticizer, TPP is added to polymers such as cellulose acetate and polyvinyl chloride to increase their flexibility and durability. Its flame-retardant properties are utilized in the manufacturing of plastics, textiles, and electronic components to reduce their flammability. TPP also finds application as a solvent in the synthesis of certain chemicals and as a lubricant additive.

The production of TPP typically involves the reaction of phosphorus oxychloride with phenol. While TPP is generally considered to have low toxicity, concerns have been raised regarding its potential environmental persistence and bioaccumulation. Regulatory bodies in various regions have established guidelines and restrictions on its use in certain consumer products. Research continues into the environmental fate and potential health effects of triphenyl phosphate.
