Technology Process of POTASSIUM HEXAFLUORONIOBATE

There total 4 articles about POTASSIUM HEXAFLUORONIOBATE 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:

niobium + potassium hydrogenfluoride (1279123-63-5) → potassium niobium hexafluoride (16919-14-5)

Guidance literature:

With HNO₃; In hydrogen fluoride; aq. HF; dissoving of NB in 60-% aq. HF, addition of HNO3, precipitating with solution of KH2F in 60-% aq. HF;; washing with aq. HF, recrystallization from aq. HF, drying;;

Reference yield:

K(1+)*BrF4(1-)=K[BrF4] (15705-87-0) + {BrF2}(1+)*NbF6(1-)={BrF2}NbF6 (72229-87-9) → potassium niobium hexafluoride (16919-14-5)

Guidance literature:

With solvent: BrF₃;; In further solvent(s);

DOI:10.1039/JR9500001046

Reference yield:

potassium fluoride (7789-23-3) + niobium pentafluoride (7783-68-8) → potassium niobium hexafluoride (16919-14-5)

Guidance literature:

In hydrogen fluoride; aq. HF; evaporation of solution in a stream of dry N2;; crystallization on cooling down to 0°C;;

upstream raw materials:

potassium hydrogenfluoride

K⁽¹⁺⁾*BrF₄^(1-)=K[BrF₄]

{BrF₂}⁽¹⁺⁾*NbF₆^(1-)={BrF₂}NbF₆
