Application:	Dehydrating agent used for halogenation with tetrabutylammonium halides. Process for Producing Halogenated Heteroaryl Compounds
Application:	Phosphorus pentachloride has been used for the vaccum distillation of 1-methyl-2-pyrrolidinone (NMP), which was employed as mobile phase in a chromatographic analysis. It may be used as one of the reaction components in the synthesis of dichlorine heptoxide (Cl₂O₇) and transition-metal phosphides (Ni₂P, Co₂P and MoP). P₂O₅supported on alumina can be used for the solvent-free and microwave-assisted preparation of 1, 5-benzodiazepine analogs. P₂O₅/KX (X = Br, I) reagent system may be used for the transformation of alcohols into the corresponding alkyl iodides and bromides.
Application:	Phosphorus pentoxide/methanesulfonic acid (PPMA) may be used as a condensing agent and solvent for the synthesis of: • High molecular weight poly(benzoxazole)s via direct polycondensation of aromatic dicarboxylic acids containing phenyl ether structure with 3,3′-dihydroxybenzidine dihydrochloride. • Aromatic poly(phenylene ether ether ketone)s via direct self-polycondensation of 4-(4′-phenoxyphenoxy)benzoic acids. • 1,3-1H-dibenzimidazole-benzene by the reaction of isophthalic acid with 1,2-diaminobenzene.
General description:	Phosphorus pentoxide is a deliquescent compound prepared by reacting phosphorus with air. It is a commonly used as dehydrating and condensing agent in organic synthesis.
