The magnesium-aluminum precursor with the structure of hydrotalcite, confirmed by XRD and FTIR, was transformed into mixed metal oxides by a thermal activation at 450, 500, 550 or 600°C for 16 h. The obtained catalysts were characterized with respect to their textural properties (surface area, total porosity and pore size distribution) and used in the gas-phase aldolization of acetone. The effect of reaction temperature and calcination conditions on the catalytic performance was studied. The highest initial conversion of acetone (87.1%) with the selectivity to isophorone of 89.7% was measured for the hydrotalcite-derived Mg-Al oxides calcined at 600°C in the reaction carried out at 240°C.
