Bio-based 5-HMF is a versatile material with valuable market potentials. As high as 90 % fructose conversion and 93 % 5-HMF selectivity were achieved in a designed water-dioxane-methyl isobutyl ketone (MIBK) system with amberlyst 70 as dehydration catalyst by continuous flow processing. The addition of organic solvent greatly increased the dehydration rate. Furthermore, FTIR analysis demonstrated the higher stability of 5-HMF in this solvent system and thereby reducing the side reactions. The catalyst showed an efficient stability after 10 h in continuous flow at 120 °C without significant change of the catalytic performance.
