Abstract:
Method for producing solutions which comprise 5-hydroxymethylfurfural (HMF) and have a reduced content of starting materials of the HMF synthesis or a reduced content of by-products of the HMF synthesis (hereinbelow called product solution), which comprises treating solutions which comprise HMF starting materials or by-products of the HMF synthesis and an organic solvent having at least two ether groups (for short polyether) (hereinbelow called starting solution) in an evaporator with steam.
