Sodium tetrafluoroborate Chemical Properties,Uses,Production
Chemical Properties
white crystals or powder, crystallizes in the anhydrous form as clear, orthogonal, stubby prisms. Anhydrous NaBF4 does not etch glass. Readily soluble in water. Rhombic crystals, isodimorphous with NaClO4.
Uses
Sodium Tetrafluoroborate is used in various metal finishing and plating circuits.
General Description
Sodium tetrafluoroborate (NaBF4) is colorless sodium salt and its crystals belong to the rhombic crystal system. It can be synthesized by reacting tetrafluoroboric acid with sodium carbonate or hydroxide.
Safety Profile
Moderately toxic by subcutaneous route. When heated to decomposition it emits toxic fumes of Fand Na2O.
Synthesis
Boric acid (6.2 g.) is added, with cooling, to 25 g. of 40% hydrofluoric acid contained in a Pt dish. The mixture is left standing for
six hours at room temperature, then cooled with ice, and 5.3 g of
dry Na2CO3 is added. The solution is then evaporated until crystallization starts. The salt can be recrystallized from water, whereby
large, beautiful single crystals can be obtained. The NaBF4 is
finally dried under vacuum.
2 H3BO3 + 8 HF + Na2CO3 = 2 NaBF4 + 7 H2O + CO2
Purification Methods
Crystallise the fluoroborate from hot water (50mL/g) by cooling to 0o. Alternatively, free it from insoluble material by dissolving it in a minimum amount of water; then fluoride ions are removed by adding concentrated lanthanum nitrate in excess. After removing lanthanum fluoride by centrifugation, the supernatant is passed through a cation-exchange column (Dowex 50, Na+-form) to remove any remaining lanthanum [Anbar & Guttman J Phys Chem 64 1896 1960]. It has also been recrystallised from anhydrous MeOH and dried in a vacuum at 70o for 16hours. Keep it dry as it is hygrosopic. [Delville et al. J Am Chem Soc 109 7293 1987.]
