Phosphoroxytrichlorid
WebDescription Phosphorus (V) oxychloride is widely used as a dehydrating agent and a chlorinating agent. Useful for the conversion of amide to nitriles, Bischler-Napieralski reaction, Vilsmeier Haak reaction, and other reactions producing commercially important intermediates. Acts a source of liquid phosphorus in semiconductor industry. Phosphorus trichloride is an inorganic compound with the chemical formula PCl3. A colorless liquid when pure, it is an important industrial chemical, being used for the manufacture of phosphites and other organophosphorus compounds. It is toxic and reacts readily with water to release hydrogen chloride.
