Raw Materials | Chlorine Phosphorus pentoxide |
colorless liquid. Relative density 1. 82(15 ℃). Melting Point -16.5 °c. The boiling point of 47 degrees C (10_3mmHg), 90~92 degrees C (10~12mmHg). When placed in the air, the smoke (after some time) will react strongly with water.
Under cooling (- 30 °c)
In this case, it is carefully reacted with water to produce dichlorophosphoric acid (HPO2 Cl2). Soluble in phosphorus trichloride, phosphorus oxychloride, thionyl chloride, benzene and other hydrocarbons, ether, nitrobenzene.
use | for pharmaceuticals. Used as laser material and electronic component. This product is mainly used in pharmaceutical chemistry, and can be used as an intermediate and phosphating agent for synthesis reactions It is used in pharmaceutical and other organic synthesis, as laser materials and electronic components. |
production method | the mixture of phosphorus oxychloride and phosphorus pentoxide (molar ratio 8:1) is put into a reaction tube and heated at 200 ℃ for 48h, the reaction product is moved to a flask immersed in a hot water bath, unreacted phosphorus oxychloride is distilled by decompression method (12mnHg), and then distilled at 250 ℃ and 12 mmHg on a sand bath. The product is repeatedly distilled under reduced pressure on a boiling water bath to produce pure pyrophosphoryl chloride. Its 4POCl3 P2O5 → 3P2O3C14 |
