RECOVERY OF BF3 FROM OLEFIN OLIGOMER PROCESSAbstract of the DisclosureA process for recovering BF3 from a BF3-promoter catalyzed .alpha.-olefin oligomerization process isdisclosed wherein the oligomer reaction product is waterwashed to extract BF3 as its hydrate and any watersoluble promoter and the water extract is distilled toremove components boiling below BF3 hydrate overheadleaving a residual product which is at least 50 weightpercent BF3 in the form of BF3 hydrate.
