Tributyl phosphate

Tributyl phosphate (TBP, CAS 126-73-8) is a phosphoric acid ester used industrially as a solvent, plasticizer, and flame retardant.

Where is Tributyl phosphate used?

• Nuclear fuel reprocessing and rare earth metal extraction: selective solvent for separating metal ions from aqueous streams
• Printing inks and surface coatings: solvent and defoamer that reduces surface tension
• Plastics and polymers: plasticizer and flame-retardant additive in cellulose acetate, PVC, and polyurethane systems
• Lubricants and metalworking fluids: anti-wear additive and carrier solvent for active ingredients
• It dissolves both polar and non-polar compounds for extraction, formulation, and process chemistry.

Commercial specifications

• Purity levels typically ranging from 98% to 99%+ for process-sensitive applications
• Clear liquid in drum and IBC quantities, with bulk tanker options
