설명

일반 설명

Phosphorus pentoxide (P₂O₅) is a phosphorous oxide. It participates in Pictet-Gams synthesis. Phosphorus pentoxide supported on alumina has been used for solvent-free and microwave-assisted synthesis of 1, 5-benzodiazepine derivatives.

애플리케이션

Phosphorus pentoxide may be used in the synthesis of dichlorine heptoxide (Cl₂O₇).
