| 摘要 |
The present invention relates generally to processes for converting fructose-containing feedstocks to a product comprising 5-(hydroxymethyl)furfural (HMF) and water in the presence of water, solvent and an acid catalyst. In some embodiments, the conversion of fructose to HMF is controlled at a partial conversion endpoint characterized by a yield of HMF from fructose that does not exceed about 80 mol%. In these and other embodiments, the processes provide separation techniques for separating and recovering the product, unconverted fructose, solvent and acid catalyst to enable the effective recovery and reutilization of reaction components. |
