| Hazard Information | Back Directory | [Description]
Tetraethylammonium tetrafluoroborate is a quaternary ammonium salt consisting of a positively charged tetraethylammonium cation and a negatively charged tetrafluoroborate anion. This compound is commonly used as a phase transfer catalyst in organic chemical reactions, facilitating the transfer of reactants between immiscible phases. It can also be used as a reagent for synthesizing various organic compounds, an electrolyte in electrochemical experiments, and a source of tetraethylammonium ions in biochemical and pharmacological research.
| [Chemical Properties]
white crystals or crystalline powder | [Uses]
Tetraethylammonium Tetrafluoroborate is used in the preparation of some organic salts of fluoboric acids. | [General Description]
| [Synthesis]
(1), boric acid refining: Specific operations are as follows: Industrial boric acid dissolved in boiling deionized water, and then filtered, the filtrate is reduced to room temperature, crystallization, filtration, and washed with deionized | [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.] |
