Phosphorus trichloride

Description:
Phosphorus trichloride (PCl₃) is a colorless to yellowish liquid with a pungent odor, commonly used as a chlorinating agent in organic synthesis and as an intermediate in the production of various phosphorus-containing compounds. It has a molecular weight of approximately 137.33 g/mol and a boiling point around 76 °C. PCl₃ is highly reactive, particularly with water, producing phosphoric acid and hydrochloric acid, which makes it a hazardous material that requires careful handling. It is also a polar molecule, exhibiting a trigonal pyramidal geometry due to the presence of a lone pair of electrons on the phosphorus atom. In addition to its applications in chemical synthesis, phosphorus trichloride is utilized in the manufacture of pesticides, flame retardants, and plasticizers. Due to its corrosive nature, it poses significant health risks, including respiratory irritation and skin burns, necessitating the use of appropriate personal protective equipment when handling. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and prevent hazardous reactions.
