제목 Synthesis Of Glycerol Carbonate By Glycerolysis Of Urea Using Metal Containing Ionic Liquid Catalyts
초록 The utilization of biomass and biodiesels in particular is now well established as a green alternative to reduce carbon emissions. One major drawback in the biodiesel industry is the production of large amounts desired glycerol as a bye product during the transesterification process which contributes a large surplus in the current glycerol market. Glycerol carbonate (GC), which can be synthesized from glycerol, is a new and interesting material in the chemical industry. In this study, we reported the catalyzed synthesis of GC from glycerol and urea using metal containing ionic liquids, (RIm)2ZnX2, which were prepared by a metal insertion reaction. The synthesized (RIm)2ZnX2 exhibited good catalytic performance during synthesis of GC from glycerol and urea. (HEIm)2ZnCl2 with a hydroxyl group exhibited the highest GC yield owing to incorporation of acid–base bifunctional active sites. (EIm)2ZnX2 catalysts based on different halide anions showed increased reactivity as Cl-<Br-<I-, which is the order of nucleophilicity. The effects of reaction parameters on the reactivity were also investigated.
