| Tetraethylammonium tetrafluoroborate Usage And Synthesis |
| Chemical Properties | white crystals or crystalline powder | | Uses | Tetraethylammonium Tetrafluoroborate is used in the preparation of some organic salts of fluoboric acids. | | General Description | Visit our Sensor Applications portal to learn more. | | Purification Methods | Dissolve the salt in hot MeOH, filter and add Et2O. It is soluble in ethylene chloride [Thompson & Kraus J Am Chem Soc 69 1016 1947, Wheeler & Sandstadt 77 2025 1955]. It has also been recrystallised three times from a mixture of ethyl acetate/hexane (5:1) or MeOH/pet ether, then stored at 95o for 48hours under vacuum [Henry & Faulkner J Am Chem Soc 107 3436 1985, Huang et al. Anal Chem 58 2889 1986]. It is used as a supporting electrolyte. [Beilstein 4 IV 333.] |
