Technology Process of Uranium tribromide

There total 5 articles about Uranium tribromide 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:

NH4(1+)*UBr4(1-)*1.5CH3CN*6H2O=NH4UBr4*1.5CH3CN*6H2O → uranium(III) tribromide (13470-19-4)

Guidance literature:

In neat (no solvent); thermal high vac. decompn. of the U(III) complex bromide at about 10**-5 to 10**-6 hPa and 20 to 300°C in a quartz tube connected to a high vac. system; elem. anal.;

DOI:10.1016/0022-5088(90)90032-F

Reference yield:

uranium(IV) bromide (13470-20-7) → uranium(III) tribromide (13470-19-4) + bromine (10097-32-2)

Guidance literature:

In neat (no solvent); on distn. of UBr4 in a stream of N, dissocn. in part into UBr3 and Br; UBr3 remains, as not volatile ppte., in react.vessel;;

Reference yield:

uranium(IV) bromide (13470-20-7) → uranium(III) tribromide (13470-19-4)

Guidance literature:

With hydrogen; byproducts: HBr; on treating of up to melting temp. heated UBr4 with H, forming of UBr3 and evolving of HBr; redn.;;
