Abstract
Alpha olefins may be oligomerized over a boron trifluoride catalyst and a protonic promoter, and then held at a temperature between 60.degree. and 150.degree. C. to increase the molecular weight of the oligomers. 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. An inert organic solvent may be present.
