A process for preparing a C<SUB>4</SUB>- to C<SUB>12</SUB>-olefin (olefin A) from another C<SUB>4</SUB>- to C<SUB>12</SUB>-olefin (olefin B), wherein olefin (A) and olefin (B) differ with regard to the position of the double bond, and wherein a gaseous mixture comprising olefin (B) and from 0.01 to 10% by weight, based on the total amount of hydrocarbon compounds in this mixture, of a compound having a dipole moment of from 0.5 to 5 debye (compound P) is contacted with a basic catalyst at a temperature of from 200 to 700° C. |
