fosforioksikloridi

Phosphorus oxychloride, also known as phosphoryl chloride, has the chemical formula POCl3. It is a colorless to pale yellow fuming liquid with a pungent odor. This compound is highly reactive and corrosive. Its primary uses are as a chlorinating agent and a catalyst in various organic synthesis reactions. Specifically, it is employed in the production of phosphate esters, which find applications as plasticizers, flame retardants, and hydraulic fluids. It is also a key intermediate in the synthesis of pharmaceuticals and pesticides. Phosphorus oxychloride reacts violently with water, producing phosphoric acid and hydrochloric acid fumes. It is also incompatible with alcohols, amines, and bases. Due to its hazardous nature, handling requires strict safety precautions, including adequate ventilation and protective equipment. It is typically stored in tightly sealed containers away from moisture and incompatible materials. The industrial production of phosphorus oxychloride commonly involves the oxidation of phosphorus trichloride or the reaction of phosphorus pentachloride with phosphorus pentoxide.
