Here we present the synthesis, characterization and the evaluation of the acid properties of a series of AlSBA-3 materials with different aluminum content obtained by postsynthesis alumination . The preparation of the mesoporous silica was based on the procedure proposed by Anunziata et al. [1]. The materials were fully characterized by different physicochemical methods showing a high-framework aluminum content (up to a bulk Si/Al ratio of 10) and good structural integrity. The nature of acid sites in AlSBA-3 has been studied using pyridine as probe molecule and by catalytic tests of 2-propanol dehydration. 1] O.A. Anunziata, M.L. Martínez, M. Gomez Costa. Mat.
