trinbutilfoszfát

Trinbutilfoszfát, often abbreviated as TnBP, is a chemical compound with the formula (C4H9O)3P=O. It is an organophosphate ester, specifically a triester of phosphoric acid and n-butanol. TnBP is a colorless to pale yellow liquid that is generally insoluble in water but soluble in many organic solvents. Its physical properties make it useful in a variety of industrial applications.

Historically, TnBP has found use as a plasticizer, a substance added to plastics to increase their flexibility and durability. It has also been employed as a flame retardant in certain materials. In some contexts, it has served as a solvent and a component in hydraulic fluids. Due to its chemical structure, it can also act as a complexing agent.

However, concerns regarding the environmental persistence and potential toxicity of some organophosphate compounds, including TnBP, have led to increased scrutiny and regulation. While specific uses and restrictions can vary by region and application, the trend for such chemicals is often towards finding less hazardous alternatives or implementing stricter controls on their use and disposal. Research continues to explore its environmental fate and potential impacts on ecosystems and human health.
