Abstract (en)
[origin: DE19746280A1] Supported transition metal catalysts are obtained by suspending the support material in a non-polar aprotic solvent, adding a solution of a Group VIIIB, IB or IIB metal complex with bi- or tri-dentate ligand(s) in a polar aprotic solvent, possibly adding non-polar solvent and working up by filtration. A process for the production of supported transition metal catalysts comprises: (a) suspension of the support material in a non-polar aprotic liquid (NPAL), (b) controlled addition of a Group VIIIB, IB or IIB metal chelate complex with bi- or tri-dentate ligand(s) as a solution in a polar aprotic liquid, (c) filtration, optionally followed by washing with NPAL and (d) optionally removing liquid residues Alternatively, the mixture obtained from stage (b) may be mixed with more NPAL before performing stages (c) and (d) as above. An Independent claim is also included for supported transition metal catalysts obtained by this process.
