Description

General description

Tributyl phosphate is an endocrine disrupting compound.

Tributyl phosphate (TBP) is an organophosphorus compound widely used as a solvent in nuclear fuel reprocessing for the extraction of uranium and plutonium from other radionuclides.

Application

Tributyl phosphate was employed as:

• solvent in the solvent-detergent method for production of immunoglobulin for inactivation of viruses with lipid envelope on the model of duck hepatitis B virus
• ligand in the extraction of lanthanide ions from solid and liquid materials by supercritical CO₂
• extractant for metal complexes
