It can be prepared via the slow addition of liquid bromine to phosphorus tribromide at 0 °C, followed by the slow addition of water and vacuum distillation of the resulting slurry. It is prepared according to the equation: 3 PBr5 + P2O5 → 5 POBr3[1][2] PropertiesThin plates, faint orange tint, d 2.822. mp 56° (in hot water). bp758 193° (decomposes). Slowly hydrolyzes in water forming H3PO4 and HBr. Soluble in ether, benzene, chloroform, carbon disulfide, concentrated H2SO4. Store in sealed glass ampoules.
