20130168227 | PROCESS FOR THE PRODUCTION OF FURFURAL - Furfural is produced in one step at both high yield and high conversion from a feedstock comprising solid biomass and/or insoluble polysaccharide, in a high boiling, water-miscible solvent containing a soluble acid catalyst, and water. Furfural product and water can be distilled off, leaving non-volatile solvent behind. Because furfural contact with the acidic medium is minimized, degradation is kept to a minimum. The feedstock does not have to be pretreated. Because the biomass undergoes near complete dissolution, the residual material is flowable and easier to handle than residual solids reported from other processes. Further, certain by-products (e.g., humins, lignins) solubilized in the reaction solvent can be precipitated by addition of water or aqueous solution and then removed from the reaction mixture. | 07-04-2013 |
