ABSTRACT:
A process for the recovery of BF.sub.3 from crude oligomerization reaction product mixture containing dissolved BF.sub.3 is described, the process being characterized by vaporization of BF.sub.3 from the crude oligomerization reaction product mixture in a vaporization zone at a temperature insufficient to decompose BF.sub.3 or any BF.sub.3 promoter-complex in the mixture. BF.sub.3 from the vaporization zone is then contacted with a liquid olefin composition under conditions to absorb BF.sub.3, in an absorption zone, forming a mixture comprising liquid olefin composition and BF.sub.3. The liquid olefin composition may be utilized directly for oligomerization of the liquid olefin therein.
