Abstract

The invention relates to a process for preparing high-purity diisobutene by reaction of isobutene or isobutene-containing hydrocarbon mixtures over a solid acidic ion-exchange resin containing sulfonic acid groups whose protons have been partly replaced by metal ions and to the use of the diisobutene.
