Technology Process of Rhenium(VII)heptafluoride

There total 2 articles about Rhenium(VII)heptafluoride 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:

rhenium + fluorine (7782-41-4) → rhenium hexafluoride (10049-17-9) + rhenium(VII) fluoride (17029-21-9)

Guidance literature:

In neat (no solvent);

Reference yield:

rhenium + fluorine (7782-41-4) → rhenium(VII) fluoride (17029-21-9)

Guidance literature:

In neat (no solvent); heating Re-sponge (pre-trated with H2 at red heat) with 2-fold excess ofF2 (6 atm) slowly to 640 K during 4 h (H2-pretreated Ni-vessel); cooling to 190 K, pumping off excess F2; 95-99% purity (Raman spectroscopy);
