摘　　要：开发新型的电解质以及低温电解铝技术是促进铝工业改革创新的重要途径之一。采用N,N-二甲基丁胺、无水氯化铝为原料,混合制备得到了新型低温熔盐。结果证明,该熔盐为氯铝酸型离子液体,可以在其中实现铝的低温电沉积。在此基础上,系统考察了试验温度、电解电位、反应时间对铝的电沉积、表面形貌和化学组成的影响规律,获得了纯度较高的金属铝。有关研究为低温电解铝技术的发展及其在铝精炼和电镀铝中的应用提供了一定的科学依据。Development of new electrolytes and low-temperature aluminum electrolysis technology is one of the important ways to promote the reform and innovation in aluminum industry.A novel low-temperature molten salt was prepared by mixing N,N-dimethylbutylamine and anhydrous aluminum chloride.The results show that this molten salt is a chloroaluminate-based ionic liquid,in which aluminum can be electrodeposited at low temperature.On this basis,the effects of experimental temperature,electrolytic potential and reaction time on the electrodeposition,surface morphology and chemical composition of aluminum are investigated in detail.The high-purity aluminum is obtained.This research provides a scientific basis for the development of low-temperature aluminum electrolysis technology and its application in aluminum refining and electroplating.
