Dehydration of fructose to HMF in presence of (H3O)xSbxTe(2-x)O6 (x = 1, 1.1, 1.25) in H2O-MIBK

[EN] The pyrochlores (HO)SbTeO (x = 1, 1.1 and 1.25) obtained by ion exchange from KSbTeO oxides were used as catalysts for the conversion of fructose to 5-hydroxymethylfurfural (HMF) in HO/Methyl isobutyl ketone (MIBK). The structure of the resulting compounds as well as the location of the HO unit...
