ABSTRACT:
Ethylene is effectively oligomerized to linear alpha-olefins using catalyst systems based on transition metal compounds. It has been found that when the reaction is conducted in a polar organic liquid as solvent, incorporation of water into the solvent at levels of 1 to 10 weight percent increases alpha-olefin purity and also influences the Schulz-Flory distribution.
