| Abstract | A series of water-tolerant propylsulfonic acid and n-octyl group co-functionalized mesostructure SBA-15 were prepared by post-modification. Physico-chemical properties of synthesized catalysts were examined by N2 adsorption-desorption (BET), XRD, FT-IR, TG, TEM and acid-base titration. Catalytic performance was evaluated in the glycerol-acetic acid esterification reaction and effect of reaction temperature, reaction time, catalyst loading, and molar ratio of reactants on conversion and selectivity were investigated. Octyl-PrSO3H-SBA-15 used as catalyst could obtain 100% glycerol conversion and 89.9% diacetin and triacetin selectivity for high acid content and hydrophobicity. Water tolerance of the catalysts were examined by the addition of the increasing amount of water, and Octyl-PrSO3H-SBA-15 exhibited better water tolerance compared to less hydrophobic PrSO3H-SBA-15. Co-functionalized mesoporous catalysts are reusable, with no obvious loss in catalytic activity after nine cycles. |
