Conversion of Sawdust into 5-Hydroxymethylfurfura by Using 1,3-Dimethyl-2-Imidazolidinone as the Solvent
The conversion of the cellulose into 5-HMF would experience three steps, cellulose to glycose, glycose to fructose and fructose to 5-HMF. Chloride ion can break down the hydrogen bond in cellucose, chromium can catalyze the isomerization of glycose to fructose, and the high temperature is helpful to...
