| 摘 要： | 采用尿素和氯化四乙基铵为原料，合成了一种新型的配位离子液体，并通过红外和X－射线粉末衍射对其结构进行了表征。结果表明，尿素和氯化四乙基铵发生反应，使得原来尿素羰基峰由1690.72cm－1转移到了1619.10cm－1。由X－射线粉末衍射图可以看出，在2θ = 30.37°处有新的衍射峰。通过差热－热重分析，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。

| Abstract: | A coordinated ionic liquid ［3（CH3CH2）4N+Cl-·（NH2）2CO］ was synthesized from urea and tetraethyl ammonium chloride，and its structure was characterized by IR and XRD.The results showed that the IR absorption peak of carbonyl was at 1619.10 cm-1 compared with that of urea at 1690.72cm-1，which was due to reaction of urea and tetraethyl ammonium chloride.There was a new peak at 2θ=30.37° in the XRD pattern.The range of thermal stability is from room temperature to about 250℃，and is higher than other common organic solvents. |
