Aldol Condensation Reaction between Formaldehyde and Acetone over Heat-Treated Synthetic Hydrotalcite and Hydrotalcite-Like Compounds

Abstract Synthetic hydrotalcite, Mg6Al2(OH)16CO3·4H2O, and its analogues were synthesized, heat-treated at 773 K, and used as catalysts for the title reaction to form methyl vinyl ketone (MVK) at 673 K. MVK was formed over all the catalysts examined, the highest MVK yield (20% on acetone basis) being found over the heat-treated hydrotalcite.
