Abstract

PURPOSE:To obtain a linear alpha-olefin in high purity and improve the yield of a middle fraction, by oligomerizing ethylene in the presence of a ternary catalyst of a zirconium halide, an alkylaluminum halide compound and phosphorus compound. CONSTITUTION:A gas containing ethylene is polymerized in the presence of a mixture of (i) a compound expressed by the formula ZrXaAb (X and A are Cl, Br or I; a and b are integers 0-4 and a+b=4), preferably zirconium tetrachloride, with (ii) a compound expressed by the formula AlRcQd (R is 1-20C alkyl; q is Cl, Br or I; c and d are 1, 1.5 or 2 and c+d is 3), preferably diethylaluminum chloride and (iii) a phosphorus compound to advantageously obtain a linear alpha-olefin useful for modifying comonomers of polyolefins, etc. This method provides a higher yield of a middle fraction, e.g. about 6-20C, higher yield of the alpha-olefin in each fraction and lower composition ratio of formed waxes than well-known methods.
