  • Ethylene dimerization and catalyst therefor
    Patent number: 5166114
    Abstract: An ethylene dimerization process catalyzed by a hetergeneous catalyst comprising a nickel compound, a phosphine compound, an organoaluminum compound, and a perfluorosulfonate polymer is provided. The dimerization process comprises contacting ethylene under dimerization conditions with the catalyst which is prepared by adding a homogeneous solution, formed by mixing under ethylene pressure the organoaluminum solution with a mixture of the nickel compound and the phosphine compound, to a suspension of the perfluorosulfonate polymer in an alcohol.
