| Abstract: | The synthesis of 5-hydroxymethylfurfural was studied using sucrose as raw material and ionic liquids as the catalysts. The ionic liquids including N-methyl-2-pyrrolidonium methyl sulfonate and N-methyl-2-pyrrolidonium hydrogen sulfate was synthesized and characterized, and the catalytic dehydra- tion of sucrose by these ionic liquids was investigated. The results indicated that N-methyl-2-pyrrolidonium methyl sulfonate exhibited better catalytic properties and 5-hydroxymethylfurfural yield of 48.2% was obtained under the condition as follows：reaction time 60 min, reaction temperature 85 ~C, N2 atmosphere, N-methyl-2-pyrrolidonium methyl sulfonate dosage 10.0% （mole fraction） of sucrose and N ,N-dimethyl- formamide-lithium bromide（DMF-LiBr） as the solvent. |
