Pabst Blue Ribbon, commonly abbreviated PBR, is an American lager beer sold by Pabst Brewing Company, established in Milwaukee, Wisconsin, in 1844 and currently based in San Antonio. Originally called Best Select , and then Pabst Select , the current name comes from the blue ribbons tied around the bottle’s neck between 1882 and 1916.
PBr 3 is prepared by treating red phosphorus with bromine. An excess of phosphorus is used in order to prevent formation of PBr 5: P 4 + 6 Br 2 → 4 PBr 3. Because the reaction is highly exothermic, it is often conducted in the presence of a diluent such as PBr 3. Phosphorus tribromide is also generated in situ from red phosphorus and bromine.
Phosphorus pentabromide is a reactive, yellow solid of formula P Br 5, which has the structure [PBr 4] + Br − (tetrabromophosphonium bromide) in the solid state but in the vapor phase is completely dissociated to PBr 3 and Br 2.

Phosphorus pentachloride, phosphorus pentabromide, and phosphorus heptabromide are ionic in the solid and liquid states; PCl 5 is formulated as PCl 4+ PCl 6–, but in contrast, PBr 5 is formulated as PBr 4+ Br −, and PBr 7 is formulated as PBr 4+ Br 3−. They are widely used as chlorinating and brominating agents in organic chemistry.
3 PBr 5 + P 2 O 5 → 5 POBr 3. It can also 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. [citation needed] Structure and properties. Phosphoryl bromide forms colorless crystals or thin plates with a faint orange tint.
