fosforotrichlorid

Phosphorus trichloride, with the chemical formula PCl3, is an inorganic compound. It is a colorless fuming liquid at room temperature that hydrolyzes rapidly in moist air. Its distinct pungent odor is characteristic. Phosphorus trichloride is highly reactive and is a key intermediate in the production of numerous other phosphorus compounds, including phosphorus oxychloride and phosphorus pentachloride. It is synthesized industrially by the direct reaction of white phosphorus with chlorine gas. The reaction is highly exothermic and requires careful control. PCl3 is a vital reagent in organic chemistry, particularly in the synthesis of organophosphorus compounds used in pesticides, flame retardants, and plasticizers. Due to its corrosive nature and reactivity with water, it must be handled with extreme caution in well-ventilated areas, wearing appropriate personal protective equipment. Exposure can cause severe burns to skin, eyes, and respiratory tract. Its industrial importance stems from its versatility as a precursor to a wide range of valuable chemical products.
