摘要
Disclosed are methods of at least partially purifying HMF from an aqueous mixture containing reactants and products of HMF synthesis from fructose that relies on use of non-functional polymeric resins. A first type of non-functional polymeric resin preferentially adsorbs HMF relative to fructose and is used to remove a majority of fructose from the reaction mixture. HMF is desorbed from the first non-functional polymeric resin with an organic solvent such as acetone. A second type of non-functional polymeric resin preferential adsorbs furfural from an aqueous reaction mixture allowing HMF to pass through. In one embodiment, these non-functional polymeric resins may be used alone in combination with each other to obtain HMF of high purity. In other embodiments, one or more of the foregoing non-functional polymeric resin resins is used in combination with cation exchange chromatography to still further purify the HMF.
