ABSTRACT:
An improved catalytic composition for oligomerization, in particular dimerization, of monoolefins comprises the product resulting from bringing the following three constituents into contact in any order:a) at least one divalent nickel compound;b) at least one hydrocarbylaluminium dihalide, optionally enriched with an aluminium trihalide; andc) at least one organic Bronsted acid;the catalytic composition being pre-conditioned in a solvent before using it for oligomerization.
