FIELD: petroleum chemistry, synthesis of linear α-olefins C8-C18. SUBSTANCE: synthesis is carried out by ethylene oligomerization in the medium of aromatic hydrocarbon or haloid-containing hydrocarbon solvent at 70-120 C on the catalytic system. Catalytic system consists of zirconyl carboxylate of the formula ZrO(OCOR)nCl2-nR, R C3-C16-alkyl, n 1 or 2, ethylaluminiumsesquichloride or simple ether of the formula R2O where R C2-C5-alkyl, phenyl or tetrahydrofuran at the molar ratio 1:(10-30):(1-5). EFFECT: enhanced selectivity of process. 1 tbl
