摘要：

In this study synthesis and characterization of solid acid catalysts with definite textural properties (high surface area, narrow pore size dimension, ordered structure) are described. In particular sulphated zirconia (SZ) has been introduced on three ordered mesoporous silica, MCM-41, MCM-48 and SBA-15, in order to study the influence of silica supports on textural and chemical-physical properties of final catalysts. The correlation between the catalytic behavior of SZ supported samples and their textural and chemical physical properties was studied in the liquid-phase acylation of anisole with benzoic anhydride.
