Triphenyl phosphate Chemical Properties,Uses,Production
Chemical Properties
Colorless, crystalline powder; odorless. Soluble in most lacquers,
solvents, thinners, oils; insoluble in water.
Combustible.
Uses
Triphenyl Phosphate is used in the insecticidal composition. Also acts as a flame retardant.
Definition
ChEBI: An aryl phosphate resulting from the formal condensation of phosphoric acid with 3 mol eq. of phenol.
Uses
Noncombustible substitute for camphor in celluloid; rendering acetylcellulose, nitrocellulose, airplane "dope", etc., stable and fireproof; impregnating roofing paper; plasticizer in lacquers and varnishes.
Reactivity Profile
Organophosphates, such as Triphenyl phosphate, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Hazard
Toxic by inhalation. Cholinesterase
inhibitor. Questionable carcinogen.
Purification Methods
Crystallise the phosphate from EtOH or pet ether (b 60-80o)/EtOH. [Cox & Westheimer J Am Chem Soc 80 5441 1958, Krishnakumar & Sharma Synthesis 558 1983, Cherbuliez in Organo Phosphorus Compounds (Kosolapoff & Maier eds) Wiley Vol 6 pp 211-577 1973, Beilstein 6 III 658, 6 IV 720.]
