| titleOfInvention | Method and device for preparing 5-hydroxymethylfurfural from high fructose corn syrup |
| abstract | The invention discloses a method and a device for preparing 5-hydroxymethylfurfural from high fructose corn syrup, which take the high fructose corn syrup as a raw material and acid as a catalyst, and respectively convert fructose and glucose in the high fructose corn syrup into the 5-hydroxymethylfurfural through continuous step-by-step reaction in an aqueous solution. Aiming at the condition difference of fructose and glucose conversion in the high fructose corn syrup, the invention adopts a mode of connecting double reaction kettles in series, fructose and glucose are respectively converted into 5-hydroxymethylfurfural through continuous stepwise reaction in aqueous solution, pure organic solvent is added in the reaction process, and 5-hydroxymethylfurfural in the reaction system is transferred to an organic layer in real time to extract 5-hydroxymethylfurfural in real time, so that the yield of 5-hydroxymethylfurfural is further improved, the continuously extracted organic solvent is recycled through reduced pressure distillation, and the water phase can be reused for many times after impurities are removed by an adsorption tower, so that the production cost is effectively reduced on one hand, the discharge of three wastes is reduced on the other hand, and the environmental protection pressure in the production process is reduced. |
