Phosphorus pentoxide is used as a reagent in organic synthesis, such as the following fields:
√ Dehydrating agent (the most effective dehydrating agent below 100°C).
√ Manufacturing of phosphorus oxychloride and phosphoric acid.
√ Intermediate for phosphate esters, which are used as surfactants, hydraulic fluids and plasticizers.
√ Important raw material for many organic syntheses in manufacturing of phosphorus compounds.
