Phosphoroxytrichlorid
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula POCl3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. It is … See more Like phosphate, POCl3 is tetrahedral in shape. It features three P−Cl bonds and one strong P=O double bond, with an estimated bond dissociation energy of 533.5 kJ/mol. On the basis of bond length and … See more POCl3 reacts with water to give hydrogen chloride and phosphoric acid: O=PCl3 + 3 H2O → O=P(OH)3 + 3 HCl Intermediates in the conversion have been isolated, including … See more In one commercial application, phosphoryl chloride is used in the manufacture of phosphate esters. Triarylphosphates such as triphenyl phosphate and tricresyl phosphate are … See more With a freezing point of 1 °C and boiling point of 106 °C, the liquid range of POCl3 is rather similar to water.
