Outline of Final Research Achievements

Glucose and its derivatives were directly converted to 5-hydroxymethyl-2-furfural (5-HMF) in aqueous medium under pressurized CO2 in the absence of any other reagents, such as non-volatile acids. This procedure is free from neutralization of the reaction mixture is not necessary. The maximum yield of 5-HMF was 92% in the reaction at 90 °C under 7.0 MPa of CO2.
