Applications

Tri-n-butyl phosphate is used as a solvent for rare earth metals exaction and purification, and as a flame retardant component of aircraft hydraulic fluid. It is involved in the formation of stable hydrophobic complexes with some metals. It is also employed as a defoamer additive in cement casings for oil wells, as an anti-air entrainment additive for coatings and floor finishes and as a solvent in nuclear fuel processing. Further, it is used as a solvent in inks, synthetic resins, gums and adhesives. In addition, it is used as a plasticizer for cellulose esters like nitrocellulose and cellulose acetate.

Notes

Incompatible with strong oxidizing agents, strong bases and alkali.
