Tetrafluoroaluminate

Of the fluoroaluminates known, cryoflte, ie, sodium hexafluoroaluminate [15096-52-2], Na AlF, has been an integral part of the process for production of aluminum. Recently, the mixtures of potassium tetrafluoroaluminate [14484-69-6], KAIF, and potassium hexafluoroaluminate [13575-52-5], K AlFg, have been employed as bra2ing fluxes in the manufacture of aluminum parts.

The activity of the apoderivative can be fully restored by addition of vanadate [45], Addition of other metal ions did not restore bromoperoxidase activity [1,2], Vanadate is only fully incorporated in the absence of phosphate [45], Like phosphate, molybdate, arsenate, tetrafluoroaluminate (A1F4 ), and tetrafluorober-rylate (BeF42 ) are also reported to be competitive inhibitors of bromoperoxidase reactivation by vanadate [47],... 

Salts of the tetrafluoroaluminate (TFA) anion have been known for many years. Yet aqueous routes to pure materials have not been established despite the substantial amount of literature available on the subject. The present review will discuss the various synthetic methods that have been employed and will demonstrate a revised method for preparing pure TFA salts. These materials are important because TFA is able to stimulate various guanosine nucleotide-binding proteins (G-proteins) and inhibit P-type ATPases by serving as a nonhydrolyzing phosphate mimic. Additionally, various TFA salts serve as precursors to aluminum trifluoride, which is used as a catalyst for chlorofluorocarbon isomerizations and fluorinations.

The commercially utilized Al-F compounds are inorganic and synthetic in origin. Thus, cryolite (Na3AlF6), used on a substantial scale (millions of tons per year), can be synthesized from soda, alumina, and hydrofluoric acid [6], Preparations of tetrafluoroaluminate salts are executed mostly in situ due to the small amounts of material needed for the various applications. AlF3 is a catalyst for various reactions (see below) and can be prepared, by the thermolysis of [AlF ]-containing salts [7]. More detailed and specific syntheses were subsequently developed, as described below.
