摘要
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.
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.
