Abstract
The electrochemistry of l-butyl-3-methyl-1H-imidazolium tetrafluoroborate (BmimBF 4 ) ionic liquid was investigated by cyclic voltammetry and Osteryoung square wave voltammetry. Impurity chloride was identified, its concentration was determined and a way to eliminate it was demonstrated. Constant current electrolysis of BmimBF 4 was performed and products were analyzed by 1 H, 13 C, and 19 F-NMR and gas chromatography-mass spectrometry. BF 3 and fluorocarbons are produced at the anode while Bmim + undergoes dimerization and dealkylation reactions at the cathode after reduction to a carbene.
