CATALYTIC SYSTEM FOR OLIGOMERIZATION OF OLEFINS, METHOD FOR ITS PREPARING AND OLIGOMERIZATION METHOD Russian patent published in 2003 - IPC

Abstract RU 2212936 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to cationic catalytic systems for oligomerization of individual C₃-C₁₄- olefins or their mixtures in bases for synthetic poly-alpha-olefinic oils (PAOO). Invention describes catalytic system for cationic oligomerization of individual C₃-C₁₄-olefins or their mixtures in bases of synthetic PAOO. The system comprises active aluminum or its alloys, for example, with magnesium or titanium as materials (bodies) with developed surface, halide-organic compound RX as co-catalyst wherein R is primary, secondary or tertiary alkyl, allyl, acetyl or benzoyl; X is chlorine, bromine or iodine atom being the system comprises from 1 to 50 moles of halide-organic compound per each g-atom of aluminum. Invention describes method for preparing this composition and method for oligomerization of individual C₃-C₁₄-olefins or their mixtures in bases of synthetic PAOO. The proposed catalytic system shows enhanced activity, output and allows regulation of the oligomerization rate. EFFECT: improved properties, enhanced effectiveness of system. 10 cl, 7 tbl, 120 ex
