摘要： Process for the oligomerisation of ethylene to give a high proportion of C.sub.4 -C.sub.8 oligomers of which a high proportion (>80%) are .alpha.-olefins, using, as catalyst a Group VIII metal hydrocarbyl compound supported on an inorganic oxide which has surface hydroxyl groups with which the compound will react. Nickel is the preferred Group VIII metal.

摘要： Ethylene is oligomerized to predominantly .alpha.-olefins, principally butene-1 with some hexene-1, by contacting it with a catalyst comprising the product of reacting a weak field ligand complex of a Group VIII metal with a particulate inorganic oxide possessing sufficient Bronsted acidity to displace one of the ligands from the complex, in the presence of a Group I to III metal hydrocarbyl. Nickel and cobalt are preferred metals, typical weak field ligands being acetylacetonate and carboxylate. Preferred inorganic oxide supports are aluminium and zirconium phosphates. Selectivities of >90% may be obtained.
