fosforioksikloridin

Phosphorus oxychloride, also known as phosphoryl chloride, has the chemical formula POCl3. It is a colorless liquid with a pungent odor and is highly reactive. Phosphorus oxychloride is a key industrial chemical used in the production of a wide variety of compounds.

Its primary applications include the manufacturing of phosphate esters, which are used as flame retardants, plasticizers, and hydraulic fluids. It also plays a role in the synthesis of pesticides and herbicides. In organic chemistry, phosphorus oxychloride serves as a chlorinating and dehydrating agent, and is used in reactions such as the Vilsmeier-Haack reaction for formylating aromatic compounds.

Phosphorus oxychloride is corrosive and reacts vigorously with water, producing phosphoric acid and hydrogen chloride gas. It is also toxic and can cause severe burns upon contact with skin and eyes. Due to its hazardous nature, it must be handled with extreme caution in well-ventilated areas and with appropriate protective equipment. Storage should be in tightly sealed containers away from moisture and incompatible materials.
