NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing comprehensive insights into the chemical compounds we supply, and Tributyl Phosphate (TBP), CAS 126-73-8, is no exception. This organophosphorus ester exhibits a unique set of chemical properties that underpin its extensive use across various industries. Understanding these properties is key to appreciating TBP's versatility and effectiveness.

TBP is characterized by its clear, colorless liquid appearance and a mild, ester-like odor, though it is often described as odorless in its pure form. Its molecular formula is C12H27O4P, with a molecular weight of approximately 266.31 g/mol. A critical property is its low vapor pressure and high boiling point (around 289 °C), which contribute to its stability and suitability for applications involving elevated temperatures. Its density is slightly less than water, typically around 0.979 g/mL at 25 °C.

The solubility profile of Tributyl Phosphate is noteworthy. While it has limited solubility in water (approximately 0.6 g/100 mL), it is miscible with most common organic solvents. This characteristic makes it an effective co-solvent and an excellent medium for dissolving resins, gums, and other substances that are difficult to solubilize in water alone. This property is fundamental to its use in the production of inks and coatings.

As a plasticizer, TBP enhances the flexibility and workability of polymers such as nitrocellulose, cellulose acetate, and polyvinyl chloride (PVC). It reduces the glass transition temperature of these polymers, making them more pliable and easier to process. This application is vital in manufacturing flexible films, coatings, and other plastic components.

In its role as a flame retardant additive, TBP works by disrupting the gas-phase and condensed-phase mechanisms of combustion. Upon heating, it can decompose to release phosphoric acid, which acts as a flame inhibitor. This property is crucial for materials requiring enhanced fire safety, and its compatibility with various polymers ensures its effectiveness as a flame retardant without significantly altering the base material's properties.

The utility of Tributyl Phosphate extends to its function as an extractant in metal extraction processes. Its ability to selectively complex with certain metal ions, like those of rare earth elements and uranium, makes it invaluable in solvent extraction circuits. The high efficiency of metal extraction using tributyl phosphate has made it a standard in industries such as nuclear fuel reprocessing and mineral processing.

Furthermore, TBP serves as a lubricant additive, contributing to antiwear and extreme pressure properties. It also functions as an industrial defoamer in various systems, reducing surface tension and preventing foam formation. These diverse applications underscore the compound's adaptability and widespread industrial relevance.
