Technology Process of Selenium bromide (Se2Br2)

There total 38 articles about Selenium bromide (Se2Br2) 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: 90.0%

selenium (7782-49-2) + selenium(IV) oxide (7446-08-4) + bromine (7726-95-6) → diselenium dibromide (1015938-55-2,7789-52-8)

Guidance literature:

With sulfur dioxide; In water; simultaneous addition of Br2 and introduction of SO2 into a soln. of SO2 in ice water; after decoloration, SeO2 and Se are added; addition of concd. H2SO4; cooling;; washing with concd. H2SO4;;

Reference yield:

sulfuryl dichloride (7791-25-5) + selenium dibromide (22987-45-7) → selenium tetrachloride (10026-03-6) + diselenium dibromide (1015938-55-2,7789-52-8)

Guidance literature:

In tetrahydrofuran; dry Ar-atmosphere; standing for 12 h; not isolated, reaction followed by (77)Se-NMR spectroscopy;

Reference yield:

SeO2*2HBr → selenium(IV) oxide (7446-08-4) + selenium tetrabromide (7789-65-3) + selenyl bromide (7789-51-7) + hydrogen bromide (10035-10-6,12258-64-9) + diselenium dibromide (1015938-55-2,7789-52-8)

Guidance literature:

In neat (no solvent); byproducts: Br2, H2O; heating at 115°C;;

upstream raw materials:
