Chromium and aluminium salts were identified as the most promising catalysts. The effect of process variables like initial D-glucose concentration (0.1-1.5 M), reaction time (5-360 min) and reaction temperature (100-140 °C) on the yield of HMF were examined at a fixed Al(OTf) 3 concentration (50 mM). Highest yields of HMF (60 mol%) were obtained using 1 M D-glucose (16 wt%), Al(OTf) 3 (5 mol%) at a temperature of 140 °C. A reaction pathway involving initial isomerisation of D-glucose to D-fructose followed by a number of dehydration steps is proposed. Kinetic analysis reveals that the reaction is second order in D-glucose with an activation energy of 138 kJ mol -1. © The Author(s) 2012.
