20160185794 | METHOD FOR SELECTIVELY PREPARING EVOGLUCOSENONE (LGO) AND OTHER ANHYDROSUGARS FROM BIOMASS IN POLAR APROTIC SOLVENTS - A method to produce 5-hydroxymethylfurfural (HMF) is described in which a reactant including cellulose, lignocellulose, or a combination thereof, in a reaction mixture of a polar, aprotic solvent and an acid is reacted for a time, at a temperature, and at a hydrogen ion concentration wherein at least a portion of the cellulose or lignocellulose present in the reactant is converted to HMF. The reaction mixture is initially substantially devoid of water. As the reaction proceeds, dehydration of intermediates causes the water concentration in the reaction mixture to rise to no more than about 2.0 wt % water. | 06-30-2016 |
