FIELD: petrochemical processes. SUBSTANCE: ethylene is oligomerized into linear alpha-olefins in presence of catalytic system containing transition metal compound, organophosphorus sulfonate ligand and optionally catalyst activator dissolved in polar organic liquid selected from sulfolane, ethylene glycol, 1,4-butanediol, and ethylene carbonate and containing approximately between 1 and 10 wt % water. EFFECT: increased purity of alpha-olefins and decreased Schulz-Flory distribution constant. 5 cl, 6 tbl, 5 ex |
