  • Use of a solid hydrotalcite structure incorporating fluorides for basic catalysis of Michael or Knoevenagel reactions
    Patent number: 7060859
    Abstract: The invention concerns the use of a solid basic catalyst comprising a hydrotalcite structure wherein part at least of the compensating anions are fluoride anions F? for producing Knoevenagel of Michael condensation reactions. The invention also concerns novel solid basic catalysts comprising a hydrotalcite structure characterized by a Mg/Al molar ratio ranging between 2.5 and 3.8 wherein at least part of the compensating anions are fluoride anions F?, and methods for preparing said novel catalysts.
    Type: Grant
