  • Catalytic composition comprising nickel, a phosphine-type ligand and a Lewis base, and use thereof in an olefin oligomerisation method
    Patent number: 10646860
    Abstract: The invention concerns a catalytic composition comprising: at least one nickel precursor with an oxidation number of (+II), at least one phosphine ligand with formula PR1R2R3 in which the groups R1, R2 and R3, which may be identical or different and which may or may not be bonded together, and at least one Lewis base, said composition having a molar ratio of the phosphine ligand to the nickel precursor of less than or equal to 5 and a molar ratio of the Lewis base and phosphine ligand together to the nickel precursor of greater than or equal to 5.
    Type: Grant
    Filed: December 13, 2016
    Date of Patent: May 12, 2020
    Assignee: IFP Energies Nouvelles

  • Catalytic composition comprising nickel and a phosphine-type ligand, and use thereof in an olefin oligomerisation method
    Patent number: 10633303
    Abstract: A process for the dimerization of ethylene to 1-butene, carried out with a catalytic composition comprising: at least one nickel precursor with an oxidation number of (+II), at least one phosphine ligand with formula PR1R2R3 in which the groups R1, R2 and R3 may be identical or different and which may or may not be bonded together, and at least one activating agent selected from the group formed by chlorinated and brominated hydrocarbylaluminium compounds, used alone or as a mixture, the composition having a molar ratio of the phosphine ligand to the nickel precursor in the range 5 to 30 and a molar ratio of the activating agent to the phosphine ligand greater than or equal to 1.

  • Catalytic composition comprising nickel and a ligand of the phosphane complexed with nickel type, and use thereof in a olefin oligomerisation method
    Patent number: 10300473
    Abstract: The invention concerns a catalytic composition comprising: at least one nickel precursor with an oxidation number of (+II) containing a phosphine ligand complexed with nickel, at least one Lewis base, and at least one activating agent selected from the group formed by chlorinated and brominated hydrocarbylaluminium compounds, used alone or as a mixture, in a manner such that the molar ratio of the ensemble of the Lewis base and phosphine ligand complexed with the nickel of the composition to the nickel is in the range 5 to 30. The invention also concerns the use of said catalytic composition.
