tetrahydrofuran are found to be the most suitable solvents for the dehydration of fructose at high concentrations, in which 77.7% and 78.8% yields of 5-hydromethylfurfural (5-HMF) are obtained, respectively, from 20 wt% fructose in the presence of an acid catalyst (5 mol% HCl, 11 wt% water). The high proportion of fructofuranose formed in those polar aproticsolvents and the reversible dimerization to the protective
