Technology Process of Pentaiodotantalum

There total 11 articles about Pentaiodotantalum 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: 83.0%

hydrogen iodide (10034-85-2) + tantalum pentachloride (7721-01-9) → tantalum pentaiodide (14693-81-3)

Guidance literature:

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

DOI:10.1039/DT9900002743

Reference yield:

tantalum(V) oxide + aluminium(III) iodide (7784-23-8) → aluminum oxide (1333-84-2,1344-28-1) + tantalum pentaiodide (14693-81-3)

Guidance literature:

stoichiometric ratio of educts, 230-235°C for 24 h in closed, evacuated tube;

Reference yield:

hydrogen iodide (10034-85-2) + tantalum pentabromide (13451-11-1) → tantalum pentaiodide (14693-81-3)
