Technology Process of Cerium bromide (CeBr3)

There total 17 articles about Cerium bromide (CeBr3) 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%

[(H2O)7Ce(μ-Br)2Ce(OH2)7] bromide → cerium(III) bromide (14457-87-5)

Guidance literature:

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

DOI:10.1016/j.poly.2010.02.027

Reference yield:

cerium(IV) oxide + aluminium bromide (7727-15-3) → aluminum oxide (1333-84-2,1344-28-1) + cerium(III) bromide (14457-87-5)

Guidance literature:

With aluminium; In solid; byproducts: O2; CeO2, AlBr3 (Ln:Al = 1:4) and Al powder were placed into an one-end sealed quartz tube under Ar, sealed under vac., heated at 600 K for 1 h; sealed tube was placed in a tubular furnace with a reduced temp. gradient from 750 to 460 K, vapor transport reaction for 6 h, tube was quicklyremoved from the furnace, the hot end was quenched with water, AlBr3 wa s condensed;
