Description
- General description: Phosphorus pentoxide can be prepared by reacting phosphorus with air. It is commonly used as a dehydrating and condensing agent in organic synthesis.[1]
- Application: Phosphorus pentoxide may be used for the vacuum distillation of 1-methyl-2-pyrrolidinone (NMP), which was employed as mobile phase in a chromatographic analysis.[2]It may be used as one of the reaction components in the synthesis of dichlorine heptoxide (Cl2O7)[3] and transition-metal phosphides (Ni2P, Co2P and MoP).[4] P2O5 supported on alumina can be used for the solvent-free and microwave-assisted preparation of 1, 5-benzodiazepine analogs.[5] P2O5/KX (X = Br, I) reagent system may be used for the transformation of alcohols into the corresponding alkyl iodides and bromides.[6]
