Title: Catalytic composition and process for the selective oligomerization of ethylene to light linear alpha-olefins
Inventor(s): Biagini, Paolo; Gila, Liliana
Patent Assignee(s): Polimeri Europa S.p.A., Italy
Source: PCT Int. Appl., 55 pp. CODEN: PIXXD2
Language: English

Abstract:
The invention relates to a catalytic composition for the selective oligomerization of ethylene and a process for preparing light linear alpha-olefins, especially 1-hexene and 1-octene, starting from ethylene, using this composition, said composition comprising: (A) a compound of a transition metal M of Group 4 of the periodic table; (B) an organic compound containing the sulfonic group (>SO2) bonded to two carbon atoms; (C) a hydrocarbyl organometallic compound of a metal M' selected from elements of Groups 1, 2, 12, 13 or 14 of the periodic table; components (A), (B) and (C) being in such a quantity that the atomic ratios resp. of the metal M in (A), of the sulfur S in the sulfonic group of (B) and of the metal M' in (C), respect the following proportions: S/M = (from 0 to 20)/1 and M'/M = (from 2 to 2000)/1, on the condition that when the compound of the metal M in component (A) is not a sulfonic complex of M, the S/M ratio is greater than 0.5, preferably greater than 1.
