Comparison of niobium and zirconium oxides-based catalysts and super acidified ion exchange resins as efficient catalysts for dehydration of fructose to hmf
Background: The obtaining of HMF from fructose reaction was studied using a continuous packed bed tubular reactor (PBR) using catalysts based on niobium and zirconium compounds, as well as modified ion exchange resins (resins CT275 and SGC650H superacidificated) and, using as solvents, DMSO and aqueous solutions of DMSO. Among all catalysts prepared, the superacidificated ion exchange resins presented the best performance, followed by the catalysts based on zirconium compounds and those produced with niobium compounds.
