以己内酰胺和四乙基氯化铵为原料,合成了一种新型的配位离子液体[(CH3CH2)4N+Cl-.3C6H11NO],并绘制了(CH3CH2)4N+Cl-/C6H11NO的二元体系相图。通过红外和XRD对其结构进行了表征。通过差热-热重分析,该配位离子液体在室温到250℃可以稳定存在,与其他有机溶剂相比具有良好的稳定性。
A novel coordination ionic liquid [(CH3CH2) 4N + Cl-.3C6H11NO] was synthesized using caprolactam and tetraethylammonium chloride as raw materials, and a binary system of (CH3CH2) 4N + Cl- / C6H11NO Phase Diagrams. Its structure was characterized by IR and XRD. The complex ionic liquids are stable at room temperature to 250 ℃ by DTA - TGA and have good stability compared with other organic solvents.
