Abstract
In a process for the oligomerization of alpha olefins using a boron trifluoride/alcohol catalyst complex a method for recovering the boron trifluoride from the product stream which comprises lowering the pressure of the product stream to flash off excess boron trifluoride, mixing the boron trifluoride with fresh alcohol to form fresh boron trifluoride/alcohol catalyst complex, and introducing the fresh catalyst back into the oligomerization reactor.
