  • Patent number: 7297806
    Abstract: Alpha-olefin are manufactured in high yield and with very high selectivity by contacting ethylene with an iron complex of a selected 2,6-pyridinedicarboxaldehyde bisimine or a selected 2,6-diacylpyridine bisimine, and in some cases a selected activator compound such as an alkyl aluminum compound. Novel bisimines and their iron complexes are also disclosed. The ?-olefin are useful as monomers and chemical intermediates.

  • Patent number: 7271121
    Abstract: Methods for making ?-diimine metal complexes are described. The methods comprise forming an ?-diimine metal complex imine bond in the presence of a metal salt or an ?-acylimine metal complex. The method is particularly using for the production of ?-diimine metal complexes having two different ?-diimine nitrogen groups. The ?-diimine metal complexes are useful for polymerizing or oligomerizing olefins.

  • Patent number: 7268096
    Abstract: Novel ?-diimine metal complexes, particularly iron complexes are disclosed. The ?-diimine metal complexes are produced by forming one of the ?-diimine metal complex imine bonds in the presence of a metal salt or an ?-acylimine metal complex. ?-diimine metal complexes having two different ?-diimine nitrogen groups may be produced. The ?-diimine metal complexes are useful for polymerizing or oligomerizing olefins.

  • Patent number: 7223893
    Abstract: Linear 1-butene dimers and other linear alpha-olefin dimers are manufactured in high yield and with high selectivity by coupling of alpha-olefins. The coupling is accomplished by contacting alpha olefins with an iron-based catalyst activated with an aluminum-based co-catalyst. The catalyst is structured to preclude formation of multiple dimer products, and the byproducts of the olefin coupling consist almost exclusively of methyl branched olefin dimers. The dimers have potentially diverse use in areas stretching form pharmaceuticals to plastics. Linear 1-butene dimers may be particularly useful in the production of plasticizer alcohols which may in turn be used to manufacture high quality plastics with reduced leaching.

  • Patent number: 7129304
    Abstract: Processes to polymerize or oligomerize olefins by contacting olefins with ?-diimine metal complexes. In particular, alpha olefins can be produced in high selectivity by contacting ethylene with selected ?-diimine metal complexes. In some cases an activator such as an alkylaluminum compound is also contacted with ethylene and the ?-diimine metal complexes.

  • Patent number: 7056997
    Abstract: Novel metal complexes, particularly chromium complexes, which contain at least one tridentate ligand are disclosed and prepared. Olefins, particularly ethylene, can be reacted to form butene and/or other homo- or co-oligomers and/or polymers with high ?-olefin concentrations by contacting a metal catalyst which contains a transition metal, particularly chromium, complexes having per metal atom at least one tridentate ligand with N, O, or N and O coordinating sites.
