Process for the co-oligomerisation of ethylene and alpha olefins

摘要

A process for production of higher linear alpha olefins and/or alkyl-branched alpha olefins, which comprises the co-oligomerisation of one or more alpha olefins with ethylene in the presence of a metal catalyst system employing one or more bis-aryliminepyridine MX_a complexes and/or one or more [bis-aryliminepyridine MY_p.L_b⁺][NC^-]_q complexes; and said process is carried out at an ethylene pressure of less than 2.5 MPa.
