Abstract
A process for the oligomerization of olefin fractions where boron trifluoride in the gas phase is contacted with such a fraction, in the absence of a catalyst carrier, under such conditions and for such a length of time that the isobutene and/or butadiene present will polymerize; the boron trifluoride and the isobutene and/or butadiene polymers obtained are then conventionally separated from said fraction; and the olefins of the fraction so purified are oligomerized in the presence of a boron trifluoride catalyst comprising a catalyst carrier.
