Abstract: The butenes are oligomerized with Ziegler-Natta catalysts composed of (CH3COO)2Ni, (CH3(CH2)3CH(C2H5)COO)2Ni, (C2H5)2AlCl and (C2H5)1.5AlCl1.5 repective-ly.The components in butene dimers are analysed.The course of the formation of active species is discussed.The reaction mechanism of butene oligomerization is deduced.

Key words: Ziegler-Natta catalyst, Nickel hydride active species, Butene oligomerization, Reaction mechanism
