Safety and Handling Guidelines

While Tributyl Phosphate (TBP) is a valuable industrial chemical, it requires proper handling to mitigate potential health and environmental risks.
TBP is classified as a toxic organophosphorus compound that can be absorbed through the skin and may cause irritation to eyes, skin, and respiratory tract upon exposure.

Personal Protective Equipment:
Wear chemical-resistant gloves, safety goggles, and protective clothing. Use in well-ventilated areas or with respiratory protection if vapors are present.

Storage:
Keep in cool, dry, well-sealed containers away from strong oxidizers, bases, and heat sources. Incompatible with strong oxidizing agents and certain plastics or rubbers.

Spill Response:
Absorb with inert material and dispose as hazardous waste. Avoid water contamination.

Firefighting:
Use foam, CO₂, or dry chemical extinguishers. Collect runoff separately to prevent environmental release.

Frequently Asked Questions (FAQs)

What is Tributyl Phosphate (TBP) used for?
TBP is primarily used as a solvent and extractant in nuclear reprocessing, plasticizers in polymers, and defoamers in industrial fluids. Its solvency makes it versatile for adhesives, inks, and flame-retardant coatings.

Is TBP safe to handle?
TBP requires careful handling due to its irritant and toxic properties. It can cause skin/eye irritation and is harmful to aquatic life. Follow SDS guidelines, use protective equipment, and ensure proper ventilation to mitigate risks.

Can TBP be used in food-contact applications?
No, TBP is not approved for food-contact materials due to its toxicity profile. It's strictly for industrial and non-food uses, such as in pharmaceuticals for extraction only.

How does TBP compare to other phosphate esters?
TBP offers better solvency and lower volatility than triethyl phosphate (TEP), making it preferable for extraction processes, though it has a higher molecular weight for added stability.

Is TBP flammable?
TBP has a flash point of 146°C and is combustible but not highly flammable. Handle away from open flames and use appropriate fire suppression methods.
