van Grieken, R.Morales, G.Martin, A.Martinez, F.2010-05-212010-05-212008Studies in Surface Science and Catalysis 174A (2008) 345-348http://hdl.handle.net/10115/4008Organically-modified mesoporous silica materials have been prepared by direct co-condensation of styrylethyltrimethoxysilane (STETMOS) and tetraethylorthosilicate (TEOS) in one-pot synthesis. The polimerizable nature of the styryl-containing precursor induces the formation of anchored polystyrene blocks over the silica surface, which are amenable to be functionalized with acid groups via sulfonation. The resultant organosulfonic-modified mesostructured silica materials have exhibited hexagonal long-range mesoscopic arrangement with extended surface areas and narrow mean pore size distributions. The acid capacity of these materials was assessed on the acid-catalyzed reaction test of anisole acylation with acetic anhydride.enAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Químicainfo:eu-repo/semantics/article10.1016/S0167-2991(08)80213-3info:eu-repo/semantics/openAccess23 Química
