ABSTRACT:
A novel ethylene dimerization catalyst is provided consisting essentially of a nickel compound, a phosphine compound, and an acidic compound. In addition, an improved ethylene dimerization process is provided which comprises contacting ethylene with the novel catalyst composition present, in an effective solvent, at a temperature from about 0.degree. C. to about 200.degree. C. As a result of the inventive precess, high catalyst productivity and good selectivity to the desired dimerized product, 1-butene, is obtained.
