Abstract:

Aluminum phosphor tungstate(AlPW12O40) catalyst was prepared by ionexchange technique andcharacterized by FT-IR, XRD, potentiometric titration and ICP.The AlPW12O40 was used to catalyze the conversion of glucose to 5-hydroxymethylfurfural(5-HMF) under hydrothermal condition.The effects of reaction temperature, reaction time, amount of catalyst and volumeratio of solvent on the yield of 5-HMF were investigated.The research results showed that the yield of 5-HMF reached 19.18% at 200℃for 1.5 h with 80 mg AlPW12O40in the solvent system of γ-valerolactone (GVL) and water with the volumeratio of 0.10.AlPW12O40 had strong acidity, and Al3+ contributed to the isomerization of glucose into fructose.The solvent system of γ-valerolactone and water (volume ratio 0.10) inhibited the isomerization of glucose and promoted the direct dehydration of fructose.The yield of 5-HMF was enhanced via the synergistic effect of AlPW12O40 catalyst and solvent system.
