Technology Process of Ferrous bromide

There total 36 articles about Ferrous 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: 95.0%

iron + hydrogen bromide (10035-10-6,12258-64-9) → (57)FeBr2 (7789-46-0)

Guidance literature:

at 80 ℃; for 2h; Inert atmosphere; Schlenk technique;

DOI:10.1021/jacs.5b03270

Reference yield: 66.0%

iron(III) oxide + hydrogen bromide (10035-10-6,12258-64-9) → iron(II) bromide (7789-46-0)

Guidance literature:

With Graphite; at 1000 - 1400 ℃; for 0.25h; Microwave irradiation; Inert atmosphere;

DOI:10.1021/ic401914f

Reference yield:

Iron-Tellurium + bromine (7726-95-6) → tellurous acid (10049-23-7) + bromic acid (7789-31-3) + iron(II) bromide (7789-46-0)

Guidance literature:

upstream raw materials:

hydrogen bromide

iron

bromine

iron pentacarbonyl

Downstream raw materials:

Fe(P(OCH₃)3)5Br⁽¹⁺⁾*B(C₆H₅)4^(1-)=[Fe(P(OCH₃)3)5Br][B(C₆H₅)4]

Fe(P(OC₂H₅)3)5Br⁽¹⁺⁾*B(C₆H₅)4^(1-)=[Fe(P(OC₂H₅)3)5Br][B(C₆H₅)4]

trans-COFeBr(P(OCH₃)3)4B(C₆H₅)4

FeBr(CO)(P(OCH₃)3)4⁽¹⁺⁾*B(C₆H₅)4^(1-) = [FeBr(CO)(P(OCH₃)3)4]B(C₆H₅)4
