ABSTRACT:
Alpha olefins may be oligomerized over a boron trifluoride catalyst and a promoter containing a transition metal cation. When the oligomers are hydrogenated they provide a synthetic lubricant base stock having excellent properties. The alpha olefins may be derived from ethylene polymerization or wax pyrolysis. A protonic promoter and an inert organic solvent may be present.
