Technology Process of Niobium(V) iodide

There total 11 articles about Niobium(V) iodide 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: 82.0%

hydrogen iodide (10034-85-2) + niobium pentachloride (10026-12-7) → niobium(V) iodide (13779-92-5)

Guidance literature:

In further solvent(s); byproducts: HCl; Under Ar, dissolving in EtBr, connecting the flask to a vac. line and a HI cylinder, a black ppt. forms immediately from the yellow soln., this operation is four times within 2 h repeated, stirring of the suspn. (15 h, room temp.).; Filtn., drying in vac., elem. anal.;

DOI:10.1039/DT9900002743

Reference yield:

niobium + iodine (7553-56-2,12190-71-5,8031-47-8) → niobium(V) iodide (13779-92-5)

Guidance literature:

In neat (no solvent); 450°C, sealed glass tube; elem. anal.;

Reference yield:

niobium + iodine → niobium(V) iodide (13779-92-5)

Guidance literature:

In neat (no solvent); evacuated molten tube inclined to horizontal; heating 20 % excess of I in lower tube part first at 180°C later at 250°C and niobium in other tube part at 300°C for 10-15 hours; pptn. of NbI5 in limit zone;; removal of iodine by pumping off at 10E-5 Torr and ambient temp. or washing with CCl4 or aliphatic carbon hydrogens;;
