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.
