Several aldehydes undergo disproportionation into corresponding acids and alcohols (Cannizzaro reaction) over calcined hydrotalcite, magnesium aluminum layered double hydroxide (LDH), in water. The reactions are slow and ~10% conversions were achieved after stirring for 24 h at room temperature. The mixed metal oxide obtained on calcination of the LDH gets hydrated to a meixnerite-type phase, which provides the necessary basicity for the Cannizzaro reaction. The calcination temperature of LDH, if it is above the decarbonation temperature, has no appreciable effect on the outcome of the reaction.
