Abstract
Mixed vanadium-titanium phosphates as well as individual vanadium and titanium phosphates were prepared via precipitation from sulfate aqueous solutions. Co-precipitated phosphates were modified through mechanochemical treatment (MChT) and characterized using the adsorption-structural methods. The aldol condensation of acetic acid with formaldehyde to acrylic acid has been used as a test reaction. Reduction of optimum reaction temperature from 623 K to 573 K on the treated catalysts is observed.
