Abstract
Boron trifluoride is removed from coordination compounds contaminating organic liquids by contacting the contaminated liquid with silica. For example, boron trifluoride is removed from a boron trifluoride-n-butanol coordination compound contaminating a 1-olefin oligomer product by passing the contaminated liquid oligomer through a bed of silica.
