Description of Phosphorus oxychloride
Phosphoryl chloride (commonly called OPCl3) is a colourless liquid with the formula POCl3. It hydrolyses in moist air releasing phosphoric acid and choking fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. It is mainly used to make phosphate esters such as tricresyl phosphate.

What is Phosphorus oxychloride?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is it which has developed particularly rapidly in recent years. Do you know about it?
The official answer:Phosphorus trichloride is an inorganic compound with the molecular formula POCl3 and is a colorless, transparent, fuming liquid. It is volatile and has a strong, irritating odor. When exposed to humid air, it hydrolyses phosphoric acid and hydrogen chloride and white smoke occurs. Easily decomposed by water and ethanol and emits large amounts of heat and hydrogen chloride. Highly corrosive.
What’s the application of Phosphorus oxychloride?
It is used to make phosphate esters such as diphenyl monooctyl phosphate and triethyl phosphate, plasticizers, organophosphorus pesticides, and long-acting sulfonamide drugs. Also used as intermediates of dyestuff, chlorinating agent and catalyst of organic synthesis, flame retardant.
