  • Process for the manufacture of saturated fatty acid esters
    Patent number: 8334396
    Abstract: Disclosed is a process for the manufacture of saturated fatty acid esters by subjecting unsaturated fatty acid esters to hydrogenation in the presence of a catalyst suitable for catalysing the saturation of double bonds in the esters, which is characterized in that said catalyst represents a homogenous complex of a Group VIII metal and a sulfonated phosphite as the polar ionic ligand.
    Type: Grant
    Filed: June 14, 2008
    Date of Patent: December 18, 2012
    Assignee: Cognis IP Management GmbH
    Inventors: Georgios Papadogianakis, Achilleas Bouriazos, Angeliki Tsichla, Christiana Vasiliou
  • Process for the partial hydrogenation of fatty acid esters
    Patent number: 8263794
    Abstract: Disclosed is a process for the manufacture of unsaturated fatty acid alkyl esters or glycerides having a total content of C18:1 of about 30 to about 80 Mol-%, by partial hydrogenation of unsaturated fatty acid esters having a total content of (C18:2+C18:3) of at least 65 Mol-%, calculated on the total amount of C18 moieties in the ester, wherein the hydrogenation is conducted in an aqueous/organic two-phase system in the presence of a water-soluble catalyst consisting of a Group VIII, Group IX, or Group X metal and a hydrophilic ligand.

  • Process for the partial hydrogenation of fatty acid esters
    Publication number: 20100022664
    Abstract: Suggested is a process for the manufacture of unsaturated fatty acid alkyl esters or glycerides having a total content of C 18:1 of about 30 to about 80 Mol-% by partial hydrogenation of unsaturated fatty acid esters having a total content of (C18:2+C18:3) of at least 65 Mol-%—calculated on the total amount of C18 moieties in the ester—which is characterised in that the hydrogenation is conducted in an aqueous/organic two phase system in the presence of a water soluble catalyst consisting of a Group VIII metal and a hydrophilic ligand.
