Catalytic Synthesis of 1-Butene by Ethylene Dimerization

Catalytic dimerization of ethylene is the basis of modern technologies for obtaining high-purity butene-1, a valuable intermediate product of petrochemical synthesis, which is in demand primarily in the production of polymers for various purposes. The paper summarizes current information on the areas of use of butene-1 in the chemical industry and technologies for its catalytic synthesis from ethylene, and identifies trends and approaches in the development of catalysts for selective dimerization of ethylene.
