DECENE-1 OLIGOMERIZATION CATALYST Russian patent published in 2023 - IPC C07C2/32 B01J31/22 B01J21/06 C10G50/02 

FIELD: chemical industry.

SUBSTANCE: invention relates to the field of industrial production of branched hydrocarbons with a homogeneous molecular structure, which are decene-1 oligomers. The invention also relates to a catalyst and its application for the oligomerization of decene-1. The catalyst includes a compound of general formula I characterized by the presence of two indeno[1,2-b]indole fragments connected by a dimethylene bridge, characterized by the presence of a substituent R¹ at position 2 and a substituent R² at position 3 of one of the indeno[1,2-b]indole fragments, where R² is hydrogen when R¹ is an alkyl substituent, or R1 is hydrogen when R2 is an alkyl substituent. The advantage of this group of inventions is to increase the conversion of decene-1 and to increase the yield of oligomers in the process of oligomerization of decene-1.

EFFECT: use of the proposed catalyst at the stage of obtaining decene-1 oligomers provides a significant improvement in the characteristics of the base of poly-alpha-olefin oils.
