Menetelmä katalyytin poistamiseksi oligomeerituotteesta

摘要

Method for removing catalyst from an olefinic oligomerization product, comprising the steps of oligomerizing one or more olefins in presence of a BF3 cocatalyst complex, and distilling the oligomerization product while separating vaporized BF3 cocatalyst complex, said distillation step comprising, simultaneously to said separation of BF3 cocatalyst complex, a separation of vaporized unreacted monomer from a bottom product which becomes substantially free from BF3 cocatalyst complex.
