    3. Effect of Different Ionic Liquids on 5-Hydroxymethylfurfural Preparation from Glucose in DMA over AlCl3: Experimental and Theoretical Study

      Yan Yang, Wentao Liu, Ningning Wang, Haijun Wang, Wei Li and Zhanxin Song

      Article first published online: 30 MAR 2015 | DOI: 10.1002/cjoc.201500030

      Thumbnail image of graphical abstract

      A series of ionic liquids which possess the same cation and different anions were synthesized to explore the effect of anions on 5-hydroxymethylfurfural (HMF) preparation from glucose over AlCl3. Systematic experiments showed that N-methyl-2-pyrrolidone bromide ([NMP]Br) could promote selective conversion of fructose. Theoretical study indicated that Br could also combine with Al3+, accelerating process of H-shift during glucose isomerization. This discovery can help us choose cocatalysts for low toxic metal, realizing selective conversion of cellulosic biomass conversion.
