    • A process for the recovery of BF3 from crude oligomerization reaction product mixture containing dissolved BF3 is described, the process being characterized by vaporization of BF3 from the crude oligomerization reaction product mixture in a vaporization zone at a temperature insufficient to decompose BF3 or any BF3-promoter complex in the mixture. BF3 from the vaporization zone is then contacted with a liquid olefin composition or liquid olefin composition and a promoter composition capable of forming a complex with BF3, in an absorption zone, forming a mixture comprising liquid olefin composition and BF3 and/or BF3-promoter complex. The mixture may be utilized directly for oligomerization of the liquid olefin.
    • 描述了从含有溶解的BF 3的粗制低聚反应产物混合物中回收BF 3的方法,该方法的特征在于,在不足以分解BF 3或任何BF 3 - 促进剂的温度下,在汽化区中从粗制低聚反应产物混合物中汽化BF 3 复杂的混合物。 然后使来自蒸发区的BF 3在液体烯烃组合物或液体烯烃组合物和能够与BF 3形成络合物的助催化剂组合物的吸收区中与包含液体烯烃组合物和BF 3和/或BF 3 - 助催化剂络合物的混合物接触 。 该混合物可以直接用于液体烯烃的低聚。
