Linear 1-butene dimers and other linear alpha-olefin dimers are manufactured in high yield and with high selectivity by coupling of alpha-olefins. The coupling is accomplished by contacting alpha olefins with an iron-based catalyst activated with an aluminum-based co-catalyst. The catalyst is structured to preclude formation of multiple dimer products, and the byproducts of the olefin coupling consist almost exclusively of methyl branched olefin dimers. The dimers have potentially diverse use in areas stretching form pharmaceuticals to plastics. Linear 1-butene dimers may be particularly useful in the production of plasticizer alcohols which may in turn be used to manufacture high quality plastics with reduced leaching.

丁烯二聚体和其他线性α-烯烃二聚体。偶联反应是通过将α-烯烃与铝基协同催化剂活化的
铁基催化剂接触而完成的。该催化剂的结构可避免多种二聚体产物的形成,而烯烃偶联的副产物几乎完全由甲基支链烯烃二聚体组成。这些二聚体在从制药到塑料等各个领域中具有潜在的多样化用途。线性1-
丁烯二聚体在生产可塑剂醇方面可能特别有用,这些可塑剂醇反过来可以用于制造具有减少渗漏的高质量塑料。
