ABSTRACT:
Preparation of a hydrocarbon-soluble nickel complex substantially free of moisture comprising reacting a nickel compound with an organic complexing agent in a hydrocarbon solvent to form a complex, allowing the complex to settle and separate into a water phase and a hydrocarbon solution of the complex, then drying the hydrocarbon solution of complex by azeotropic distillation. The substantially anhydrous nickel complex obtained can be mixed with an alkylaluminum halide to form a catalyst system useful for the dimerization of olefins.
