Product Details
Preparation |
Lithium tetrafluoroborate, LiBF4, is prepared by dissolving LiF in AHF and then BF3 gas is passed until precipitation is complete. After the reaction is over, excess HF is decanted and LiBF4 is dried under nitrogen until HF and H20 contents are reduced below 100 ppm level. Reaction is carried out in Teflon(R), polyethylene or polypropylene lined reactors to avoid metallic contamination. |

Purification Methods |
Dissolve it in THF just below its solubility, filter from insoluble material and evaporate it to dryness in a vacuum below 50o. Wash the residue with dry Et2O, and pass dry N2 gas over the solid and finally heat it in an oven at 80-90o. Its solubility in Et2O is 1.3g in 100mL at 25o; in THF it is 71g in 100mL at 25o. It is hygroscopic and is an IRRITANT. [Elliott et al. J Am Chem Soc 74 5211 1952, 75 1753 1953.] |
