Triphenyl phosphate Chemical Properties,Uses,Production

Chemical Properties

Colorless, crystalline powder; odorless. Soluble in most lacquers, solvents, thinners, oils; insoluble in water. Combustible.

Chemical Properties

Triphenyl phosphate is a colorless crystalline powder with a faint, phenol-like odor.


Triphenyl Phosphate is used in the insecticidal composition. Also acts as a flame retardant.


ChEBI: An aryl phosphate resulting from the formal condensation of phosphoric acid with 3 mol eq. of phenol.


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.


Toxic by inhalation. Cholinesterase inhibitor. Questionable carcinogen.

Safety Profile

Poison by subcutaneous route. Moderately toxic by ingestion. Absorbed slowly, particularly by skin contact. Not a potent cholinesterase inhibitor. Combustible when exposed to heat or flame. To fight fire, use CO2, dry chemical. When heated to decomposition it emits toxic fumes of POx. See also TRITOLYL PHOSPHATE.

Potential Exposure

Triphenyl phosphate is used to impregnate roofing paper and as a fire-resistant plasticizer in plastics; for cellulose esters in lacquers and varnishes. Used in making adhesives, gasoline additives; flotation agents; insecticides, surfactants, antioxidants, and stabilizers. A substitute for camphor.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, rinse mouth and get medical attention.


UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

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.]


Incompatible with strong oxidizers; strong acids; nitrates may cause fire or explosions. Phosphates are incompatible with antimony pentachloride, magnesium, silver nitrate, zinc acetate.

Waste Disposal

Incinerate in furnace equipped with alkaline scrubber.
