METHOD FOR OBTAINING LIGOMERS OF ALPHA-OLEFIN C, C OR C Russian patent published in 2015 - IPC C07C11/02 C07C2/32 C07C2/34 C10G50/00

Abstract RU 2570650 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining oligomers of alpha-olefin C₆, C₈ or C₁₀, which includes preparation of olefin raw material, stage of oligomerisation in presence of inert solvent and postmetalocene catalytic system, which contains coordination compound of alcoholate of 5 group of Periodic table metal with organic polydentate ligand and cocatalyst. Method is characterised by the fact that stage of oligomerisation is carried out at temperature from 25 to 80°C, ratio alpha-olefin:solvent equal 1:1-3:1, in presence of reactivator - ethyltrichloroacetate in concentration 10-20 mole/ml³. Catalytic system contains coordination compound of vanadium alcoholate in concentration 0.1-1.0 mole/ml³, and as cocatalyst - diethylaluminium chloride or sesquiethylaluminium chloride in concentration 20-50 mole/ml³.

EFFECT: increase of catalytic activity and selectivity of catalyst with respect to formation of target product with predominant content of trimers.
