| Application: | Tributyl phosphate is used as: • An extractant for monocarboxylic acids(formic, acetic, and propionic) from an aqueous medium. • An additive to enhance the performance of dye-sensitized solar cells (DSSCs). • A solvent in combination with ionic liquid[1-butyl-3-methyl imidazolium tetrafluoroborate] for the extraction of phenol and chlorophenols. |
| General description: | Tributyl phosphate (TBP) is an organophosphorus compound. TBP is a strong Lewis base and interacts with acids. It is used as a solvent for rare earth extraction and the nuclear fuel cycle. Additionally, TBP is used as a plasticizer for cellulose esters, lacquers, plastics, and vinyl resins |
