Jr.AbstractEthylene and/or propylene is dimerized by contacting the monoolefin with a catalyst formed by depositing a nickel complex such as bis(3-picoline)dichloronickel or bis(tributylphosphine)dichloronickel on a solid support such as silica-alumina. Preferably, an aluminum compound such as diethylaluminum chloride is also used in preparing the catalyst. |
