ABSTRACT:
Spent boron trifluoride catalyst is removed from organic liquids by contacting the liquid with polyvinyl alcohol. For example, boron trifluoride catalyst is removed from 1-olefin oligomer product by passing the liquid oligomer through a bed of granular polyvinyl alcohol. The boron trifluoride is recovered from the polyvinyl alcohol and is recycled for use as a catalyst.
