    Abstract: A catalytic solid based on complexed TiCl3 is obtd. by heating, in presence of a halogenated activator, the liq. resulting from contacting TiCl4, pre-treated with an electrodonor, with a compsn. (C) of formula AlRp(Y)qX3-(p+q), where R = hydrocarbon gp.; Y = OR', SR' or NR'R''; R', R'' = hydrocarbon gp. of H; X = halogen; p, q = 0-3; p+q = 0-3.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently producing a high-purity linear α-olefin in a simple operation with improved catalytic activity and suppressed byproduct polymer formation. SOLUTION: This method for producing a linear α-olefin comprises oligomerization of ethylene in the presence of a Ziegler-Natta type catalyst; wherein the above catalyst is characterized by being prepared by incorporating an organometallic compound as the cocatalyst with 0.05-1 molar time, based on the organometallic compound, of a heterocompound with the electron density of the heteroatom determined by molecular orbital calculation being 5.8-6.5.
