Abstract
A method for catalytically synthesizing furaneol, which uses a specific peptide to function as a catalyst, uses rhamnose to function as a raw material, and uses an organic solvent and a phosphate buffer to function as a reaction solvent to be co-heated to prepare furaneol.
Claims10
A method for catalytically synthesizing furaneol, comprising:
- (1) mixing rhamnose, phosphate buffer with a pH of 5-7, organic solvent, and a peptide, heating to a reflux state after a nitrogen gas replacement, and reacting until a content of the furaneol in an organic phase no longer changes to obtain a material, wherein a reaction temperature is 60-120° C., a reaction time is 3-6 hours, the peptide consists of 2-20 amino acids and the peptide has a molecular weight of no more than 2000 Daltons;
- (2) leaving the material obtained in step (1) to stand to be cooled down to obtain an organic phase and an aqueous phase;
- and
- (3) recycling an organic solvent in the organic phase obtained in step (2), then distilling under a reduced pressure to obtain the furaneol, and recycling the aqueous phase.
