ECHEMI Editorial Reference

Triethyl phosphate is a colorless, high-boiling liquid and containing 17 wt % phosphorus; mild odor. Very stable at ordinary temperatures, compatible with many gums and resins, soluble in most organic solvents, miscible with water. When mixed with water is quite stable at room temperature, but at elevated temperatures it hydrolyzes slowly. Combustible.It is manufactured from diethyl ether and phosphorus pentoxide via a metaphosphate intermediate.
