Fosforkyslík

Fosforkyslík, also known as phosphorus oxychloride, is a chemical compound with the formula POCl. It is a colorless, fuming liquid with a pungent odor. It is highly reactive and a strong oxidizing agent. Fosforkyslík is often produced by the reaction of phosphorus pentoxide with phosphorus pentachloride, or by the reaction of phosphorus trichloride with oxygen. It is soluble in water, where it hydrolyzes to phosphoric acid and hydrochloric acid. This reaction is vigorous and exothermic, producing heat and fumes. Fosforkyslík is used in various industrial applications, including the production of plastics, pharmaceuticals, and pesticides. It serves as a chlorinating agent and a dehydrating agent in organic synthesis. Due to its corrosive and toxic nature, handling fosforkyslík requires strict safety precautions, including working in a well-ventilated area and using appropriate personal protective equipment.
