fosfororikloridin

Phosphorus oxychloride, also known as phosphoryl chloride, has the chemical formula POCl3. It is a colorless liquid with a pungent odor. The compound is highly reactive and readily hydrolyzes in the presence of water to produce phosphoric acid and hydrochloric acid. This reaction is exothermic.

Phosphorus oxychloride is primarily used as a chlorinating agent and a phosphorylating agent in organic synthesis. It plays a significant role in the production of phosphate esters, which find applications as plasticizers, flame retardants, and hydraulic fluids. It is also a precursor in the synthesis of various organophosphorus compounds.

Industrially, phosphorus oxychloride is manufactured by reacting phosphorus pentachloride with phosphorus pentoxide. The compound is corrosive and toxic, requiring careful handling and storage in moisture-free conditions. Exposure can cause severe irritation to the skin, eyes, and respiratory tract. Due to its reactivity, it is often transported and stored in specialized containers.
