Technology Process of Phosphorus pentabromide

There total 36 articles about Phosphorus pentabromide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

bromine (7726-95-6) + phosphorus pentoxide → diphosphorus trioxide + hydrogen bromide (10035-10-6,12258-64-9) + phosphorus pentabromide (7789-69-7)

Guidance literature:

In water; byproducts: PBr3; with concd. aq. HBr; distn.;

Reference yield:

{PCl4}(1+)*{PCl5Br}(1-)={PCl4}{PCl5Br} → phosphorus pentachloride (10026-13-8,874483-75-7) + bromine (7726-95-6) + phosphorus tribromide (7789-60-8) + phosphorus pentabromide (7789-69-7)

Guidance literature:

In tetrachloromethane; decomposition with deep red color in CCl4 soln., formed PBr5 partially decomposes into Br2 and PBr3;;

Reference yield:

phosphorus tribromide (7789-60-8) → phosphorus(V) bromide (7789-69-7) + bromine (7726-95-6) + phosphorus(V) oxybromide (7789-59-5)

Guidance literature:

With oxygen; In neat (no solvent); passing dry O2 at 175°C through PBr3; explosive reaction with formation of Br2, POBr3 and PBr5;;
