摘要
本文合成了1-丁基-3-甲基咪唑氯化锌([BMIM][Zn2Cl5])离子液体,通过红外光谱、TGA、DSC以及1H-NMR等方法对[BMIM][Zn2Cl5]进行了结构表征,实现了对于[BMIM][Zn2Cl5]的定性分析。以尿素醇解合成碳酸二乙酯反应为探针,考查了[BMIM][Zn2Cl5]离子液体的催化性能,结果显示,[BMIM][Zn2Cl5]表现出较好的催化活性及重复利用性能,碳酸二乙酯的收率接近30%。
Ionic liquid 1-butyl-3-methylimidazolium chlorozincate （[BMIM][ZnzC15]） was successfully synthesized, and [BMIM] [Zn2Cl5] was characterized with IR, TGA, DSC and 1H-NMR. As a result, [BMIM] [Zn2Cl5] was qualitatively analyzed successfully. [BMIM] [Zn2Cl5] was employed as the catalyst for the synthesis of diethyl carbonate by aleoholysis of urea, and [BMIM][Zn2Cl5] showed excellent catalysis performance, the yield of diethyl carbonate was near 30%. The reusability test showed that [BMIM][Zn2Cl5] catalyst had perfect utility for repeated use.
