PHOSPHORUS OXYCHLORIDE LR 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.

PHOSPHORUS PENTAOXIDE FOR SYNTHESIS Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis P4O10 + 6 H2O → 4 H3PO4 (–177 kJ). A granular form of P4O10 is used in desiccators. Consistent with its strong desiccating power, P4O10 is used in organic synthesis for dehydration.
