Mg-Al mixed oxides, prepared from hydrotalcite precursors with Mg/Al ratio varying from 2 to 7, were tested in the Guerbet reaction of methanol and ethanol to heavier products. Acidic-basic properties were followed by the adsorption calorimetry of SO2 and NH3 molecules and correlated with the catalytic activity. The results showed that the selectivity to higher alcohols is increasing with the increase of both kinds of active sites.
