Abstract

Efficient and stable solid acid catalysts, sulfonic groups functional swelling mesoporous polydivinylbenzenes (PDVB-x-SO₃Hs), were synthesized from sulfonation of swelling mesoporous polydivinylbenzenes (PDVB-xs) by chlorosulfonic acid in CH₂Cl₂. Nitrogen adsorption-desorption isotherms showed that PDVB-x-SO₃Hs have high surface area and abundant mesoporosity. Elemental analysis and acid-base titration techniques showed that PDVB-x-SO₃Hs have high concentration of sulfonic groups. Esterifications of acetic acid with cyclohexanol, hexanoic acid with ethanol, lauric acid with ethanol and acylation of anisole with acetyl chloride showed that PDVB-x-SO₃Hs are more active than arenesulfonic, propyl-sulfonic groups functional mesoporous silicas (SBA-15-Ar-SO₃H, SBA-15-Pr-SO₃H) and strongly acidic ion-exchange resin (Amberlyst 15). The superior performance of PDVB-x-SO₃Hs is attributed to their unique features including large surface area, abundance of mesoporosity as well as high content of sulfonic groups.
