The phosphoryle trichloride , or phosphorus oxychloride , is an inorganic compound of the oxychloride family, of a raw pocl formula _{3 .}

Phosphoryle trichloride reacts with water and alcohols to give hydrogen chloride and respectively phosphoric acid and phosphate esters:

Pocl _{3 + 3 H2O → H3PO4 + 3 HCl.}

Pocl _{3 peut également réagir avec un acide de Lewis tel que le tétrachlorure de titane selon le schéma réactionnel suivant :}

Cl ₃ P ⁺ -O ^– _{+ TiCl4 → Cl3P⁺-O⁻-TiCl4.}

The Pocl compound ₃ ·AlCl _{3 résultant de l’addition de chlorure d’aluminium sur le trichlorure de phosphoryle est assez stable, de sorte que POCl3 peut être utilisé pour éliminer le chlorure d’aluminium du mélange résultant d’une réaction de Friedel-Crafts.}

Pocl _{3 réagit avec le bromure d’hydrogène en présence de chlorure d’aluminium pour former le tribromure de phosphoryle POBr3.}

Phosphoryle trichloride can be prepared by oxygen action o _{2 sur le trichlorure de phosphore PCl3 à 20-25 °C (l’air est inefficace) :}

2 PCl _{3 + O2 → 2 O=PCl3.}

Alternative synthesis uses the reaction of the PCL phosphorus pentachloride _{5 avec le pentoxyde de phosphore P4O10. Dans la mesure où ces deux composés sont solides, une manière efficace de réaliser la réaction est de chlorer un mélange de PCl3 et de P4O10 afin de produire le PCl5. Au fur et à mesure que le PCl3 réagit, le POCl3 devient le solvant de réaction :}

6 PCl _{3 + 6 Cl2 → 6 PCl5.}

6 PCl _{5 + P4O10 → 10 POCl3.}

Pentachloride of phosphorus also forms phosphoryle trichloride with water, but this reaction is more difficult to control than the previous one.

This product is used in the photovoltaic industry to boost phosphorus with diffusion silicon wafers in order to make a doping n On a doped substrate p (typically in the boron) in order to make a junction p – n .
