| Abstract: | Process of microcrystalline cellulose(MC) dehydration to 5-hydroxymethyl-furaldehyde(5-HMF) using as solvent and acid ionic liquid and CrCl3 as catalysts was studied.The effect of the temperature,reaction time,catalyst content,water content were investigated respectively.When content is 4 g,MC content is 0.02 g,adding content is 1 g and CrCl3 content is 0.4 g at 130 ℃,reaction time 4 h at normal conditions the molar ratio of 5-HMF is 37%.Experimental results demonstrate that the reaction system is active for the dehydration of MC into HMF under mild conditions. |
