(205d) Influence of Water and Solvents on the Production of Levoglucosenone and 5-(Hydroxymethyl)Furfural from Cellulose
In the absence of water, cellulose is first dehydrated to form anhydro-sugar (Levoglucosan), which could be further dehydrated to LGO. The final product distribution could be controlled by the addition of water to the reaction system. Cellulose will be hydrolyzed to glucose, which could be further dehydrated to HMF. The selectivity to HMF will gradually increase with increasing water content in the solvent. A series of solvents have been screened for the production of HMF and LGO from cellulose, it has been shown that the use of polar, aprotic solvents is very promising.
