摘要
合成了氯化正丁基吡啶(BPC)和三氯化铝-氯化正丁基吡啶(A lC l3-BPC)离子液体,通过1H NMR和Raman光谱对BPC进行了结构检测.测定了酸性、中性和碱性3种A lC l3-BPC离子液体的电位窗和电导率.中性A lC l3-BPC离子液体的电位窗最宽.在一定的温度范围内,三种离子液体的电导率均随温度的升高而增大,并符合Arrhenius方程.酸性A lC l3-BPC离子液体的电导率最大,碱性次之,中性最小.
N - butylpyridinium chloride （BPC） and aluminum chloride - n - butylpyridinium chloride （ AlCl3 - BPC） ionic liquids are prepared. The obtained intermediate BPC is identified by ^1H NMR and Raman spectra. The electrochemical windows and electric conductivities of acidic, neutral and basic AlCl3 - BPC ionic liquids are measured. The electrochemical window of neutral ionic liquids is the widest of the three AlCl3 - BPC ionic liquids. The electric conductivities are increased with increasing temperature, and can be described with Arrhenius equation. The sequence of electric conductivities can be expressed as Ka 〉 Kb 〉 Kc, where Ka, Kb, and Kc are electric conductivities for acidic, basic and neutral AlCl3 -BPC ionic liquids respectively.
