Isobutene in isobutenic hydrocarbon mixtures is oligomerized over a solid acidic ion exchange resin, said acidic ion exchange resin containing, for example, sulfonic acid groups, some of whose protons have been exchanged for metal ions.

Oligomerization of isobutene in N-butenic hydrocarbon streams

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.

Method for preparing high-purity diisobutene

A process for preparing salts of methallylsulfonic acid in which the reaction mixture produced from the sulfonation is diluted with water and neutralized with a base.
