Description:
Triethyl phosphate [78-40-0] is a colorless, corrosive liquid. Combustible. Slowly dissolves in water and sinks in water. Severely irritates skin, eyes and mucous membranes. It is manufactured from diethyl ether and phosphorus pentoxide via a metaphosphate intermediate. Triethyl phosphate has been used commercially as an additive for polyester laminates and in cellulosics. In polyester resins it functions as a viscosity depressant and as a flame retardant. The viscosity-depressant effect of triethyl phosphate in polyester resin permits high loadings of alumina trihydrate,a fire-retardant smoke-suppressant filler. Triethyl phosphate has also been employed as a flame-resistant plasticizer in cellulose acetate.Because of its water solubility the use of triethyl phosphate is limited to situations where weathering resistance is unimportant.The halogenated alkyl phosphates are generally used for applications where lower volatility and greater resistance to leaching are required.

Usage
Triethylphosphate high-boiling solvents, rubber and plastic plasticizer. Also a catalyst. Also used as raw material for the preparation of pesticides. As well as ethyl reagent, for the production of ketene. In Japan, 70% of the goods for the catalyst, about 20% is used as a solvent.
Triethyl phosphate for the following purposes:
(1) a catalyst, the catalyst xylene isomers; olefin polymerization catalysts; catalyst manufacturing tetraethyl lead; Production of carbodiimide catalyst; displacement reaction catalyst and a trialkyl boron olefins; high temperature dehydration of manufacturing vinyl acetate one of the catalyst; styrene with a conjugated diene compound catalyst for the polymerization; if used when terephthalic acid and ethylene glycol to prevent polymerization of the fiber discoloration effect.
(2) Solvent nitrocellulose and cellulose acetate; organic peroxide catalyst life for holding a solvent; fluorinated ethylene dispersing solvent; as a polyester resin, an epoxy resin curing agent is a peroxide catalyst and diluent.
(3) a stabilizer, a chlorine-based pesticides and stabilizer; phenolic resin stabilizer; sugar alcohol resin solid agent.
(4) synthetic resin aspects, xylenol formaldehyde resin curing agent; softener used in shell mold of a phenolic resin; softener chloride; vinyl acetate polymer plasticizers; flame retardant polyester resin agent.
