Technology Process of Potassium tetrafluoroaluminate

There total 16 articles about Potassium tetrafluoroaluminate 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:

aluminum(III) fluoride (7784-18-1) + potassium fluoride dihydrate → potassium tetrafluoroaluminate (14484-69-6,678983-34-1)

Guidance literature:

In neat (no solvent); heating (to 400°C), isothermal treatment (0.5 h);

Reference yield:

2K(1+)*H(1+)*AlF6(3-) = K2HAlF6 → potassium tetrafluoroaluminate (14484-69-6,678983-34-1)

Guidance literature:

In neat (no solvent, solid phase); byproducts: HF, H2O; heating at 400°C; X-ray diffraction, IR, elem. anal.;

Reference yield:

aluminum trihydroxide + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) + potassium carbonate (584-08-7) → potassium tetrafluoroaluminate (14484-69-6,678983-34-1)

Guidance literature:

In water; reacting mixt. of K2CO3 in soln. with specified amt. of Al(OH)3, acidifying with excess aq. HF, drying at 100°C, annealing for 48 h; DTA anal., X-ray diffraction anal.;
