fosforitrikloridin

Phosphorus trichloride, with the chemical formula PCl3, is an inorganic compound. It is a colorless liquid at room temperature that fumes in moist air, releasing hydrogen chloride. The smell is often described as pungent and acrid. PCl3 is a highly reactive chemical and is typically produced by the direct reaction of white phosphorus with chlorine gas. It is an important intermediate in the production of many other phosphorus compounds.

Industrially, phosphorus trichloride is a key precursor in the synthesis of organophosphorus compounds, which find applications in a wide range of products. These include pesticides, flame retardants, plasticizers, and pharmaceuticals. It reacts readily with water to form phosphorous acid and hydrochloric acid. Its reactivity also makes it useful as a chlorinating agent in organic synthesis. Due to its corrosive nature and reactivity, handling phosphorus trichloride requires strict safety precautions, including working in well-ventilated areas and using appropriate protective equipment. It is incompatible with strong oxidizing agents, alcohols, and amines.
