Conversion of Cellulose to 5-HMF in the Presence of Silica-Alumina Catalysts Synthesized by Dual Template at Low Temperature

In this study, which incorporates many principles of green chemistry (use renewable feedstocks, catalysis, improvement energy efficiency, and harmless solvents auxiliaries), the single-phase catalytic conversion cellulose to 5-HMF in over silica-alumina catalysts was investigated. A series dual-template with CTAB as main template F127 or triethylamine (TEA) co-template were synthesized at a low temperature 60 °C characterized by XRD, N2 adsorption-desorption technique, FT-IR pyridine adsorption FT-IR. The surface area is increased using second catalyst. addition, acidity changed template. yield from 36% 52% 3.13% 4.24%, respectively, due properties gained 8.13% selectivity obtained aqueous medium, 220 6 h reaction time catalyst TEA co-template. Eco-friendly silica temperatures dual can be considered potential alternative for into value-added biobased products.
