Technology Process of TANTALUM (V) BROMIDE

There total 21 articles about TANTALUM (V) BROMIDE 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: 90.0%

tantalum + selenium (7782-49-2) + bromine (7726-95-6) → tantalum diselenide + [Ta(Se2)2]2(1+)*TaBr6(1-)=[Ta(Se2)2]2TaBr6 + tantalum pentabromide (13451-11-1)

Guidance literature:

In neat (no solvent); sealed quartz tube (vac.); 450°C (1 week); crystn. on cooling (20°C / h);

DOI:10.1016/S0277-5387(98)00172-7

Reference yield: 77.0%

hydrogen bromide (10035-10-6,12258-64-9) + tantalum pentachloride (7721-01-9) → tantalum pentabromide (13451-11-1)

Guidance literature:

In further solvent(s); byproducts: HCl; Under Ar, dissolving in EtBr, connecting the flask to a vac. line and a HBr cylinder, repeating of the vac./HBr-operation four times, stirring.; Filtn., drying in vac., elem. anal.;
