TBPO

TBPO (Tributyl phosphate), also known as TBP, is an organic compound and phosphoric acid ester. It is a colorless, odorless liquid that is used in various industries for its properties as a solvent and plasticizer.

Chemical Structure

TBPO is a derivative of phosphoric acid, with three butyl groups attached to the phosphorus atom. The chemical formula for TBPO is (C4H9O)3PO. It is a member of the class of compounds known as phosphate esters, which are organic compounds containing a phosphate group that is linked to exactly two alkyl or aryl groups.

Properties

TBPO is a colorless, odorless liquid at room temperature. It has a boiling point of 289°C and a melting point of -80°C. It is soluble in most organic solvents, but insoluble in water. It is stable under normal temperatures and pressures, but it can react with strong oxidizing agents.

Uses

TBPO is used in various industries due to its properties as a solvent and plasticizer. It is used in the production of cellulose acetate and vinyl resins, and as a defoaming agent in the production of antibiotics. It is also used in the extraction and purification of rare earth metals, and in nuclear reprocessing to separate uranium and plutonium.

Safety

Exposure to TBPO can cause irritation to the skin, eyes, and respiratory tract. It can also cause nausea, headache, and dizziness. Long-term exposure can lead to liver and kidney damage. Therefore, it is important to handle TBPO with care and use appropriate safety measures.
