van Grieken, RafaelMelero, Juan AntonioMorales, Gabriel2010-05-072010-05-072006Journal of Molecular Catalysis A: Chemical 256 (2006) 29-36http://hdl.handle.net/10115/3888Etherification of benzyl alcohols with 1-hexanol was performed in liquid phase over propyl- and arene-SO3H modified mesostructured SBA-15 silica. H2O TPD measurements indicate a stronger interaction of arenesulfonic acid sites with water molecules than that occurring in propylsulfonic groups. Hence, the higher catalytic activity of propylsulfonic modified SBA-15 material is related to the more hydrophobic microenvironment of -SO3H sites which reduces the acid site deactivation associated with adsorption of water generated during the reaction. Moreover, propyl- and arene-sulfonic functionalized SBA-15 material show a clear improvement of the catalytic performances as compared to other commercial homogeneous and heterogeneous acid catalysts in this particular reaction.enAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Químicainfo:eu-repo/semantics/article10.1016/j.molcata.2006.04.040info:eu-repo/semantics/openAccess23 Química
