One-Pot Conversion of Glucose into 5-Hydroxymethylfurfural using MOFs and Brønsted-Acid Tandem Catalysts
[EN] The direct conversion reaction of glucose to 5-hydroxymethylfurfural (HMF) is studied using metal organic framework (MOF) as Lewis-acid catalysts and a polyoxometalate (POM), silicotungstic acid, as a Brønsted-type acid with a mixture of 1% glucose solution in γ-valerolactone (GVL)-10% HO at 14...

| Sumario: | [EN] The direct conversion reaction of glucose to 5-hydroxymethylfurfural (HMF) is studied using metal organic framework (MOF) as Lewis-acid catalysts and a polyoxometalate (POM), silicotungstic acid, as a Brønsted-type acid with a mixture of 1% glucose solution in γ-valerolactone (GVL)-10% HO at 140 °C. The study is carried out with two routes: one using MOF and POM tandem catalysts added independently and the other through the synthesis of a composite material denoted POM@MOF. The activity tests show that the profiles of the conversion and yield of HMF achieved in both routes are similar, with the reactions with MIL-53(Al) and MIL-101(Cr) catalysts producing the highest yield of HMF (40% after 8 h of reaction). Stability tests are performed on the POM@MOF catalysts based on MIL-53(Al) and MIL-101(Cr). MIL-53(Al) and HSiW@MIL-101(Cr) can be reused, showing a progressive loss in HMF yield due to the leaching of POM. |
