Usage

General Description

Tributyl phosphate (TBP) is an organic compound used as a solvent, plasticizer, and extraction agent in various industrial processes. It is commonly utilized in the extraction of rare earth metals from mineral ores and in nuclear fuel reprocessing. TBP is also used in the production of various chemicals, including pharmaceuticals and herbicides. It is a clear, colorless liquid with a mildly fruity odor, and it is often found in combination with other solvents and chemicals. Despite its widespread use, TBP can be toxic if ingested, inhaled, or absorbed through the skin, and it can cause irritation to the eyes and respiratory system. Therefore, proper handling and safety precautions are necessary when working with TBP.
