室温离子液体FeCl_3-BPC体系的研究

FeCl_3-BPC System of Room Temperature Ionic Liquid

在充有高纯氮气的干燥手套箱内 ,将无水FeCl3 和氯化正丁基吡啶混合 ,用称重法准确配制不同组成FeCl3 和BPC混合样品 ,利用DSC方法绘制了FeCl3 BPC二元体系相图·提出了室温离子液体窗口和室温离子液体深度两个概念 ,用来衡量形成室温离子液体的能力及其性质·根据相图 ,指出了这个体系能形成含过渡金属的室温离子液体 。

In a glove box system filled with only dry nitrogen, FeCl 3 BPC(n butylpyridinium chloride) mixtures were prepared by accurately controling the composition. The phase diagram of the binary system FeCl 3 BPC was constructed by DSC method. Two concepts are proposed: the room temperature ionic liquid(RTIL) window and RTIL depth which can be used to represent the capability and property of the RTIL. According to the phase diagram, the binary system FeCl 3 BPC can produce the room temperature ionic liquid containing transition metal of which the RTIL window and the RTIL depth show limited values respectively.
