Abstract

In this research, a group of silica Vanadia catalysts was prepared, by loading vanadium pentoxide at a different percentage of loading on silica using the wet-impregnation method, after the prepared catalysts were heat-treated at 500 oC. The prepared catalysts were characterized by the following techniques: Physical adsorption of N2, SEM, scanning electron microscopy, EDS analysis, XRD, FT-IR and Raman spectroscopy, titration, total surface acidity, and acid Density was determined using pyridine adsorption. Then, the catalytic activity of the catalysts prepared by the reaction of acetic acid esterification with n-butanol has been studied in a heterogeneous system was studied.
