Triethyl phosphate is an organic chemical compound with the formula (CH3CH2)3PO4 or Et3PO4, where Et is ethyl. It is a colorless liquid. It is the triethyl ester of phosphoric acid and can be called "phosphoric acid, triethyl ester".
Its primary uses are as an industrial catalyst (in acetic anhydride synthesis), a polymer resin modifier, and a plasticizer (e.g. for unsaturated polyesters). In smaller scale it is used as a solvent for e.g. cellulose acetate, flame retardant, an intermediate for pesticides and other chemicals, stabilizer for peroxides, a strength agent for rubber and plastic including vinyl polymers and unsaturated polyesters, etc.[4]
History
It was studied for the first time by French chemist Jean Louis Lassaigne in the early 19th century.
