Fructose dehydration to 5-hydroxymethylfurfural over sulfated TiO2-SiO2, Ti-SBA-15, ZrO2, SiO2, and activated carbon catalysts. Industrial and Engineering Chemistry Research, 54(19), 52209-5225. doi:10.1021/acs.iecr.5b006280888-58851520-5045https://doi.org/10.1021/acs.iecr.5b00628https://hdl.handle.net/11147/5895Different sulfated catalysts including SO4/TiO2-SiO2, SO4/Ti-SBA-15, SO4/ZrO2, SO4/AC, and SO4/SiO2 were tested in fructose dehydration to 5-hydroxymethylfurfural (HMF). Reactions were carried out in dimethyl sulfoxide (DMSO) at 110 °C. Characterization results indicated that no sulfur leaching was observed from SO4/ZrO2, SO4/TiO2-SiO2, and SO4/Ti-SBA-15 catalysts in the reaction tests. The SO4/TiO2-SiO2 catalyst had a high amount of strong acid sites and the highest amount of Bronsted sites. The highest selectivity to HMF at high conversion, that is, 89% selectivity at 77% fructose conversion was obtained over this catalyst. It preserved its activity after four times reuse.Activated carbonCarbonCatalystsDehydrationeninfo:eu-repo/semantics/openAccessActivated carbonCatalystsDehydrationCatalyst selectivityDimethyl sulfoxideOrganic solventsArticle2-s2.0-8493022582310.1021/acs.iecr.5b0062810.1021/acs.iecr.5b00628
