METHOD OF PRODUCING ETHYLENE OLIGOMERISATION CATALYST SYSTEM COMPONENT, CATALYST SYSTEM COMPONENT, ETHYLENE OLIGOMERISATION CATALYST SYSTEM BASED ON SAID COMPONENT AND ETHYLENE OLIGOMERISATION METHOD Russian patent published in 2015 - IPC C08F4/78 C07F11/00 C07C51/41 C07C2/32 C07C11/107 B01J23/26 

FIELD: chemistry.

SUBSTANCE: catalyst system component is obtained via mechanical activation of a solid mixture with the ratio of 2-ethyl hexanoate of group I metal:CrCl₃>1:1 and heating the activated mixture to obtain the desired product. The ethylene oligomerisation catalyst system contains an organoaluminium compound of general formula AlR₃, a complexing agent, a modifier, a solvent and a chromium-containing component obtained using the disclosed method. The ethylene oligomerisation method is carried out in the medium of a hydrocarbon solvent at temperature of 40-95°C and ethylene pressure of 1-5 MPa in the presence of said catalyst system.

EFFECT: simple method of producing a component of catalyst systems for oligomerising olefins, high output of the product when oligomerising ethylene to hexene-1, high selectivity of the process and purity of hexene-1, low probability of secondary reactions.
