Tungstophosphoric (TPA) supported on mesoporouus niobiumoxophosphate (NbP) catalysts were prepared with different loadings. The synthesized materials employed as heterogeneous solid acid catalysts for selective etherification of 5-hydroxymethylfurfural to 5-ethoxymethylfurfural. Physico-chemical properties of the catalysts were obtained by different spectroscopic techniques and their results exposed that TPA was a highly dispersed state on NbP and acidity of the catalyst enhanced due to its dispersion. The higher catalytic performance can be allied to the total acidity of the catalysts with appropriate number of Bronsted-Lewis acid sites which were directed by the contact and dispersion of TPA on support. Different reaction parameters were premeditated and 25 wt% TPA/NbP catalyst exhibited highest catalytic activity with 95% of HMF conversion and 89% of EMF yield. The catalyst is reusable without noticeable turn down in catalytic performance up to five cycles. A kinetic model for etherification of HMF was also derived.
