ABSTRACT:
Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefin monomers using certain acidic calcium montmorillonite clay catalysts. When the oligomers are prepared at a temperature greater than about 200.degree. C., and any unreacted linear olefin monomer is removed, oligomers having an iodine value less than about 3 mg/g are obtained. An even lower iodine value is obtained when a hydrocarbon possessing a tertiary hydrogen is mixed with the linear olefin feed, and the mixture is contacted with the clay at a temperature greater than about 200.degree. C. Little or no hydrogenation may be required of oligomers prepared in this manner to obtain base stocks suitable for use as synthetic lubricants.
