Technology Process of Holmium iodide

There total 6 articles about Holmium 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: 99.0%

[Ho(water)9](I)3 → holmium(III) iodide (13813-41-7)

Guidance literature:

In neat (no solvent, solid phase); byproducts: H2O; Schlenk techniques; heating Ho compd. under vacuum (1E-3 Torr);

DOI:10.1016/j.poly.2010.02.027

Reference yield:

holmium (13598-41-9,13967-65-2,14391-20-9,15125-75-4,15700-49-9,15749-97-0,15750-02-4,15832-34-5,7440-60-0) + iodine (7553-56-2,12190-71-5,8031-47-8) → holmium(III) iodide (13813-41-7)

Guidance literature:

In tetrahydrofuran; (N2); molar ratio of Ho:I2 2:3; clear THF soln. of triiodide obtained by filtration or decanting;

Reference yield:

holmium(III) oxide + hydrogen iodide (10034-85-2) → holmium(III) iodide (13813-41-7)

Guidance literature:
