| 摘要 |
An ethylene oligomerization process is provided wherein ethylene is contacted with an organonickel(II) compound, a phosphine compound and an alkylaluminum compound in a first solvent to produce a precursor reaction mixture, followed by contacting ethylene with the precursor reaction mixture and a fluorinated organoacid, preferably in a second solvent, to produce a product reaction mixture comprising the desired oligomerization product. Results of the process can be optimized by employing phosphorus-containing additives as described herein.
