Procedure

This invention is a process for producing diisobutylene. The process comprises first contacting a sulfonic acid resin with a reaction feed comprising isobutylene and tertiary butyl alcohol to produce a product stream comprising diisobutylene, isobutylene, tertiary butyl alcohol, and water. The product stream is distilled to produce a first overhead stream comprising water and isobutylene and a first bottoms stream comprising diisobutylene and tertiary butyl alcohol. Water is separated from the first overhead stream, and the resulting isobutylene-enriched stream is recycled back to the reaction step. The first bottoms stream is distilled to produce a bottoms product stream comprising diisobutylene and a second overhead stream comprising tertiary butyl alcohol and diisobutylene.
