Synthetic lubricant base stocks from long-chain vinylidene olefins and long-chain alpha- and/or internal-olefins

摘要

A process is disclosed for preparing synthetic lubricant base stocks. Synthetic lubricant base stocks may be prepared in good yield by oligomerizing long-chain olefins using certain acidic calcium montmorillonite clay catalysts. When long-chain vinylidene olefin and long-chain alpha- and/or internal-olefin are co-oligomerized, a synthetic lubricant base stock having a lower pour point is obtained.
