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
