Abstract
A method for recovering dissolved boron trifluoride from a hydrocarbon liquid in a vacuum column at moderate temperatures by trickling the hydrocarbon over metallic or ceramic packing in the column. Dissolved boron trifluoride catalyst is recovered from the crude oligomer reaction product resulting from the oligomerization of 1-decene.
