Extraction of 5-HMF from the conversion of glucose in ionic liquid [Bmim]Cl by compressed carbon dioxide

The efficient extraction of 5-hydroxymethylfurfural (HMF) from the conversion products of glucose in an ionic liquid has been achieved via charging compressed CO2 into the mixtures. The targeted and tunable extraction of HMF could be realized because of the insolubility of glucose and the tunable solubility of HMF in compressed CO2.
