    • A method of producing substantially pure HMF, HMF esters and other derivatives from a carbohydrate source by contacting the carbohydrate source with a solid phase catalyst. A carbohydrate starting material is heated in a solvent in a column and continuously flowed through a solid phase catalyst in the presence of an organic acid, or heated with the organic acid and a solid catalyst in solution to form a HMF ester. Heating without organic acid forms HMF. The resulting product is purified by filtration to remove the unreacted starting materials and catalyst. The HMF ester or a mixture of HMF and HMF ester may then be oxidized to 2,5- furandicarboxylic acid (FDCA) by combining the HMF ester with an organic acid, cobalt acetate, manganese acetate and sodium bromide under pressure. Alternatively, the HMF ester may be reduced to form a furan or tetrahydrofuran diol.
    • 通过使碳水化合物源与固相催化剂接触,从碳水化合物源生产基本上纯的HMF,HMF酯和其它衍生物的方法。 将碳水化合物原料在柱中的溶剂中加热,并在有机酸存在下连续流过固相催化剂,或者用有机酸和固体催化剂在溶液中加热形成HMF酯。 无有机酸加热形成HMF。 所得产物通过过滤纯化以除去未反应的起始原料和催化剂。 然后通过在压力下将HMF酯与有机酸,乙酸钴,乙酸锰和溴化钠混合,将HMF酯或HMF和HMF酯的混合物氧化成2,5-呋喃二羧酸(FDCA)。 或者,HMF酯可以还原形成呋喃或四氢呋喃二醇。
