CATALYST COMPOSITION FOR ETHYLENE OLIGOMERISATION AND OLIGOMERISATION METHOD Russian patent published in 2015 - IPC B01J31/22 C08F4/70 C07C2/32 

FIELD: chemistry.

SUBSTANCE: present invention relates to a catalyst composition for ethylene oligomerisation and oligomerisation methods. The catalyst composition includes iron (II), cobalt (II) or nickel (II) chloride coordinated with 2-amino-1,10-phenanthroline of formula (I) as a base catalyst and triethylaluminium as a co-catalyst. The ethylene oligomerisation method employs said catalyst composition and the molar ratio of aluminium metal in the co-catalyst to the content of the atoms of the central metal in the base catalyst ranges from 101 to less than 200 or from 30 to 50. Another ethylene oligomerisation method employs the described catalyst composition and the ethylene oligomerisation temperature ranges from -10 to 19°C.

EFFECT: high catalytic activity and practical use of said catalyst composition in oligomerisation methods.
