Abstract

Electrical conductivity (σ) of aluminum chloride (AlCl3) and 1-butyl-3-methylimidazolium chloride (BMIC) ionic liquid (IL) was investigated as a function of temperature and AlCl3 mole fraction ( X AlC l 3 ). Electrochemical impedance spectroscopy was used to measure the electrical conductivity. Composition of AlCl3:BMIC ionic liquid was varied by changing the X AlC l 3 from 0 to 0.67. The temperature was changed from 70°C to 110°C at 10°C intervals. It was found that the electrical conductivity increases with an increase in temperature. Electrical conductivity increases with X AlC l 3 from 0 to 0.5 and then starts to decrease after X AlC l 3 = 0.5. A species concentration profile was developed based on thermodynamic model at room temperature for the IL containing BMI + , Cl , AlC l 4 , A l 2 C l 7 , A l 3 C l 10 , A l 4 C l 13 , and A l 2 C l 6 at different X AlC l 3 . The only anion species presents between 0 and 0.5 X AlC l 3 are Cl and AlC l 4 . Anions like A l 2 C l 7 , A l 3 C l 10 , A l 4 C l 13 , and A l 2 C l 6 are found at higher X AlC l 3 . A good agreement between the model and the experimental data was obtained. The variations in anion concentration, molecular structure, and cation–anion interactions are to be the causes of the changes in electrical conductivity of AlCl3:BMIC system.

氯化铝和1 -丁基- 3 -甲基咪唑氯离子液体电解质的电导率和种类分布
研究了氯化铝(AlCl3)和1-丁基-3-甲基咪唑氯(BMIC)离子液体(IL)的电导率(σ)随温度和AlCl3摩尔分数(X AlCl3)的变化规律。采用电化学阻抗谱法测定其电导率。AlCl3:BMIC离子液体的组成随着X AlCl3从0到0.67的变化而变化。温度以10°C的间隔从70°C变为110°C。我们发现电导率随温度的升高而增加。电导率随X alc_3从0 ~ 0.5增大,在X alc_3 = 0.5后开始减小。基于热力学模型,建立了含BMI +、Cl−、alc4−、a2c7−、a1c110−,a1c113−,和a2c16在不同的X alc13。存在于0 ~ 0.5 X alc13之间的阴离子只有Cl -和alc4 -。阴离子如a1c17−,a1c110−,a1c113−,和a2c16在较高的X alc13中发现。模型与实验数据吻合较好。阴离子浓度、分子结构和正阴离子相互作用的变化是引起AlCl3:BMIC体系电导率变化的原因。
