Disclosed herein are oligomerization processes using feedstocks containing 1-hexene to produce an oligomer product, and methods for recovering a heavy 1-hexene oligomer from the oligomer product and hydrogenating the heavy 1-hexene oligomer. The resultant hydrogenated heavy 1-hexene oligomer can be blended with other PAO's to form 100 cSt and 40 cSt lubricant compositions, which have viscosity index and pour point properties that are equivalent to or better than respective 100 cSt and 40 cSt 1-decene PAO's.

Lubricant compositions containing hexene-based oligomers

In process for the oligomerization of an alphaolefin, a carboxylic acid modifier, such as acetic acid, is used to increase the amount of trimer and tetramer in the product.

Oligomerization of alpha olefins in the presence of carboxylic acids

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.
