| titleOfInvention | Method for preparing hydroxymethyl furfural by catalytic dehydration reaction of hexose |
| abstract | The invention provides a method for preparing hydroxymethyl furfural by catalytic dehydration reaction of hexose. The method comprises the following steps of: dissolving reaction substrates of hexose into a solvent, and adding a catalyst of halogenated succinimide to form a reaction system; and at the temperature of between 0 and 200 DEG C and under the protection of atmosphere gas, stirring the reaction system by magnetic force for dehydration reaction for 0.5 to 10 hours to prepare the hydroxymethyl furfural, wherein the catalyst of the halogenated succinimide may be N-bromosuccinimide, N-chlorosuccinimide, N-iodosuccinimide, N-fluorosuccinimide or any succinimide derivatives with substituted halogen atoms. The method has the advantages that: the catalyst of the halogenated succinimide is low in price and easily bought, and can catalyze the hexose in high efficiency as well as high selectivity to prepare the hydroxymethyl furfural; the method is environment-friendly, and the productis easily disposed; and in the whole process, only regenerated compounds such as fructose are consumed, the cost is low, the technically economical requirement is met, and the application prospect isbroad. |
