Technology Process of TERBIUM TETRAFLUORIDE

There total 28 articles about TERBIUM TETRAFLUORIDE 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: 100.0%

krypton difluoride (13773-81-4) + terbium(IV) oxide → terbium tetrafluoride (36781-15-4) + krypton

Guidance literature:

With HF; byproducts: O2; Condensing of starting materials (molar ratio KrF2:TbO2 = 3:1 or 2:1) with anhyd. HF and keeping at room temp. for 1.5-2 weeks. React. is followed from change in colour of suspn. and total pressure of liberated gases.; Sepn. of resulting fluoride from HF by decantation, detn. of F and Tb after keeping (30°C, 1 h) in vac. X-ray diffraction, elem. anal., thermal anal. Well crystd. TbF4 is obtained by keeping the product underreact. conditions, for several weeks.;

Reference yield: 63.0%

xenon difluoride (13709-36-9) + terbium(III) fluoride (13708-63-9) → terbium tetrafluoride (36781-15-4)

Guidance literature:

In neat (no solvent); heating powdered TbF3 with 4fold excess XeF2 to about 300°C for 1h, Ni-vessel, removal of excess XeF2 in vac. at room temp.;;

Reference yield:

terbium(III) fluoride (13708-63-9) + fluorine (7782-41-4) → terbium tetrafluoride (36781-15-4)

Guidance literature:

In neat (no solvent); F2 pressure 150-250 atm, 305-420°C; description of autoclave;;
