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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
