摘要
1-乙基-3-甲基咪唑氯盐(EMIC)和1-丁基-3-甲基咪唑氯盐(BMIC)与氯化铝(AlCl_(3))形成的离子液体是电解铝用离子液体中最具有工业应用前景的2种离子液体。本文采用线性伏安、计时电流、计时电位、恒电压电解、恒电流电解等电化学实验方法对比搅拌和不搅拌条件下,铝在酸性AlCl_(3)-EMIC和AlCl_(3)-BMIC 2种离子液体中的阳极溶解,以筛选出较优的电解质体系,并探究搅拌、温度、电流密度、电位等工艺参数对电解过程的影响,为工业放大提供基础数据。
The ionic liquids formed by 1-ethyl-3-methylimidazole chloride(EMIC) and 1-butyl-3-methylimidazole chloride(BMIC) with aluminum chloride(AlCl_(3)) are the most promising ionic liquids for electrolytic aluminum. In this paper, linear voltammetry, chronoamperometry, chronopotentiometry, constant-voltage electrolysis, constant-current electrolysis and other electrochemical experiments are used to compare the anodic dissolution of aluminum in acidic AlCl_(3)-EMIC and AlCl_(3)-BMIC ionic liquids under stirring and non-stirring conditions, in order to screen out a better electrolyte system. The effects of stirring, temperature, current density, potential and other process parameters on the electrolytic process are investigated to provide basic data for industrial scale-up.
