triarylfosfaattiin

Triarylfosfaattiin, also known as triphenyl phosphate (TPP), is a chemical compound with the formula (C₆H₅)₃PO₄. It is a colorless solid that is soluble in many organic solvents but insoluble in water. Triarylfosfaattiin is an ester of phosphoric acid and phenol. It is produced commercially by the reaction of phosphorus oxychloride with phenol.

Triarylfosfaattiin has a variety of applications. It is used as a plasticizer in polymers such as cellulose acetate and polyvinyl chloride, improving their flexibility and durability. It also finds use as a flame retardant, particularly in plastics and textiles, by interfering with the combustion process. Additionally, triarylfosfaattiin is employed as a hydraulic fluid and a lubricant additive due to its thermal stability and lubricating properties.

In the past, triarylfosfaattiin was also used as a plasticizer in vinyl flooring and in some consumer products. However, concerns about its potential environmental persistence and effects on aquatic organisms have led to some restrictions and a search for alternatives in certain applications. Research continues to explore its properties and potential uses while also evaluating its environmental impact.
