采用循环伏安法和奥斯特杨方波伏安法研究了l-丁基-3-甲基- 1h -咪唑四氟硼酸盐离子液体的电化学性质。对杂质氯离子进行了鉴定，测定了杂质氯离子的浓度，并给出了去除杂质氯离子的方法。对bmimbf4进行恒流电解，产物通过1h、13c、19f - nmr和气相色谱-质谱分析。在阳极产生bf3和氟碳，而Bmim +在阴极还原成碳后发生二聚化和脱烷基反应。
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.
