OLIGOMERIZATION PROCESS

摘要

K 2085 A process for the oligomerization of ethylene in which ethylene is contacted in the liquid phase at elevated pressure with a nickel-containing catalyst in the presence of a polar solvent, a product phase containing oligomer hydrocarbons and dissolved ethylene and a solvent phase containing most of the catalyst are recovered from the resulting reaction mixture, residual amounts of catalyst are removed from the said product phase at a sufficiently elevated pressure to maintain ethylene dissolved in the product phase and oligomer hydrocarbons are subsequently recovered from that phase.
