ABSTRACT:
Ammonium hydroxide is used to remove nickel ylide residue from an oligomerization reaction product obtained by contacting ethylene with a nickel ylide catalyst under oligomerization conditions. The oligomerization reaction product is contacted with ammonium hydroxide to obtain a product composed of two layers, an upper layer containing normal alpha olefins and a lower layer containing nickel ylide residue. The two layers are then separated from each other to recover the desired normal alpha olefins.
