ABSTRACT:
A process is disclosed for preparing synthetic lubricant base stocks having improved properties. Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefins using certain acidic calcium montmorillonite clay catalysts. When a mixture of alpha and internal-olefins having up to 50 wt. % internal-olefin is used, and the oligomers prepared therefrom are hydrogenated, a synthetic lubricant base stock having a higher viscosity index and a lower pour point is prepared.
