Details
Description | Sodium tetrafluoroborate is an organic compound that has the molecular formula NaBF4. The compound is a salt that forms white or colorless water-soluble rhombic crystals. It is less soluble in organic solvents and readily soluble in water. |
Preparation |
Sodium tetrafluoroborate can be prepared by reacting tetrafluoroboric with sodium carbonate or hydroxide. NaOH + HBF4 → NaBF4 + H2O Na2CO3 + 2 HBF4 → 2 NaBF4 + H2O + CO2 |
Applications |
Sodium tetrafluoroborate can be used as a catalyst for the synthesis of bis(indolyl)methanes via electrophilic substitution reaction of indoles with ketones and aldehydes. In the synthesis of ionic liquids such as trihexyl(tetradecyl)phosphonium tetrafluoroborat and 1-butyl-3-methylimidazolium tetrafluoroborate. In the laboratory, sodium tetrafluoroborate may be used for the synthesis of boron fluoride. It may also be used in the synthesis of fluoroheterocyclic and fluoro-nucleic acids. The compound is also used in metal finishing, fluxes, and plating circuits. |
Chemical Properties | white crystals or powder |
Uses | Fluorinating agent, see Lawton, Levy, J. Am. Chem. Soc. 77, 6083 (1955). |
Safety Profile | Moderately toxic by subcutaneous route. When heated to decomposition it emits toxic fumes of Fand Na2O. |
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.] |
