METHOD FOR THE EXTRACTION OF (5-HYDROXYMETHYLFURFURAL,5-HMF)

摘要

the subject of the invention is a method for production of 5 - hmf from an aqueous solution, the steps(a) providing the aqueous solution containing 5 - hmf, and an organic extraktionsmittels,(b) liquid / liquid extraction with the aqueous solution with the organic solvent again in training a dispersion is mixed in.with the organic solvent again must be such that the dispersing an aqueous raffinatphase b1 as disperse phase and an organic phase as the continuous phase in the trainalthough essentially a of 5 - hmf free aqueous raffinatphase b1 and a 5 - hmf loaded organic phase b2 will be(c) separating the organic phase from the aqueous raffinatphase b1 and b2.includes.
