The invention discloses a method for preparing 5-formyloxy methylfurfural from
fructose, and relates to 5-formyloxy methylfurfural. The method specifically comprises the following steps of mixing the
fructose and
choline chloride into a reaction container, using
hydrochloric acid as a catalyst, using a polarity
organic solvent as a reaction extracting agent, and heating to react; after reaction is finished, naturally cooling, fetching out reaction liquid, adding a certain amount of
anhydrous formic acid into the reaction liquid, and continuing to heat to react; after reaction is finished, relieving pressure and distilling to remove the
solvent, using the extracting agent to continuously extract the residues, combining the extracting agent, and relieving pressure and distilling to recycle the extracting agent; under the certain condition, distilling the residual liquid, using a saturated
sodium bicarbonate water solution to wash distilling matter, and
drying anhydrous magnesium sulfate, so as to obtain the 5-formyloxy methylfurfural with purity more than 99%. The method has the advantages that the reaction condition is mild, the
reaction system is green and recyclable, the feeding amount is high, the
yield rate is high, a new path is provided for preparation of the 5-formyloxy methylfurfural, and the added value of
biomass raw materials is further improved.
