Synthetic basestocks and process for producing same

摘要

A process is described for the production of synthetic basestocks from an alpha-olefin feedstock with carbon number in the range C7-C30 the feedstock having origin in an ethylene polymerization process, the process comprising contacting the feedstock with a solid or soluble cationic AlCl3 catalyst. After separation and distilling out of the light fraction of the oligomer, a basestock of excellent viscometric, rheological and thermal stability properties is obtained. The basestocks so obtained are also described.
