Iron will: The iron‐catalyzeddepolymerization of a range of polyethers is studied. The products of the depolymerization reactions are chloroesters, which can be used as starting materials for new polymers. In the presence of simple iron salts extraordinary catalyst activities and selectivities are feasible at lowtemperature.

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.
