Abstract
A process for the dimerization of n-butene wherein a Ziegler catalyst system composed of a nickel compound and an organoalkylaluminum is added, as a third component, with an amine and/or a quaternary ammonium chloride. The amine can be a primary, secondary or tertiary amine. This process makes it possible to selectively prepare isooctene having a low degree of branching while maintaining high catalytic activity.
