| Abstract: | Ionic liquid 1-butyl-3-methylimidazolium chlorozincate ([BMIM][Zn2Cl5]]) 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 alcoholysis 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. |
