Description: A Knoevenagel condensation reaction between ethyl cyanoacetate and benzaldehyde catalysed by Mg and Ba impregnated oxide matrices (SiO₂, Al₂O₃, Fe2O3, and ZnO). The role of the support nature in the Knoevenagel condensation activity is considered, comparing the reaction rates. The intrinsic activity of the catalysts was compared by normalising the reaction rates to the specific surface area, and relating with the partial charges of the metal and oxide species, based on the Sanderson electronegativity calculations. Results show that a general correlation can be seen with the activity and the partial charges of the species providing some insight towards acid-base site relationships. ZnO however is to be considered differently as it does not follow the correlation.
